The reasoning behind Clean Gut

The book argues that what we call diseases are really just different forms of survival mechanisms for our body.  Before chronic disease comes systemic inflammation. But before systemic inflammation comes gut dysfunction. Gut damage from leaky gut (hyperpermeability) and dysbiosis  allow toxins to enter the body and cause havoc. This book discusses how to heal the gut and intestinal flora to improve your general health.

Clean Gut diet plan – food list

There are general Clean Gut diet guidelines for phases 1 and 2, and specific guidelines for each:

Phase 1 – 21 days – drink a liquid breakfast and eat meals from the Clean Gut diet, as well as taking recommended supplements and practicing specific activities to enhance the process of gut repair

Phase 2 – 7 days – reintroduce foods into your diet over the course of a week, which will allow you to identify the foods that do not promote long-term gut health

Also guidelines for testing triggers and for a lifetime diet

Clean Gut general guidelines

Eat  |  Avoid

Clean Gut foods to eat during the program – general – “The Clean Gut Diet”

  • Fill 80% of your plate with greens and vegetables (raw, steamed, baked, cooked) and 20% with protein and good fats (meat, fish, avocado, etc.)

Clean Gut program phase 1 foods

This phase lasts for 21 days

Some foods, like beans and certain fruits, are excluded because they are difficult to digest or high in sugar, even though they are the staple of most healthy diets. Once you’ve completed the Clean Gut program, they can be reintroduced into your regular diet

Clean Gut phase 1 foods to eat

Clean Gut phase 1 foods to avoid

Clean Gut phase 2 – reintroduction

The reintroduction process is the last stage of the Clean Gut program, on days 22-28. While staying on the Clean Gut diet, reintroduce gluten and dairy over seven days. The purpose of the process is to identify your toxic triggers – foods that cause inflammation, acidity, irritation, or indigestion; also allergic reactions, food sensitivities, autoimmune reactions, mood swings, bloating, fatigue.

Gluten and dairy are the most common toxic triggers. Others are processed sugar, caffeine, and alcohol

Clean Gut phase 2 – foods to eat

  • Keep a journal to record any reactions you might have to the foods you reintroduce – anything that happens shortly after eating the food, energy levels, bowel movements, sleep, emotions
  • On the first and second days (days 22 and 23), eat gluten 2-3 times a day for two days, as well as general Clean Gut diet Foods to Eat (above). Don’t include dairy or other excluded items yet
  • On the third and fourth days (days 24 and 25), eat from the Clean Gut diet Foods to Eat (above), without any gluten
  • On the fifth and sixth day (days 26 and 27), eat simple dairy foods (e.g. milk, cheese) 2-3 times a day for two days, as well as general Clean Gut diet Foods to Eat (above). Don’t include gluten and don’t include other excluded items yet – so stay away from cereal, ice cream, and baked goods at the moment
  • On day 28, reflect on how your reactions to the reintroduced foods have been. If you had no reaction, you can keep it in your diet. If you had a mild reaction, rotate your choices of foods so that you don’t eat the irritating ones more than once a week. If you had a strong reaction, remove the food from your diet

Clean Gut phase 2 – foods to avoid

Potentially healthy or toxic foods to test after phase 2

Once you’ve finished the program, you can test other foods apart from gluten and dairy. Other foods that are commonly healthy for some and toxic triggers for others include:

  • Corn
  • Eggs
  • Soy
  • Red meat
  • Nightshade vegetables (potatoes, tomatoes, peppers, eggplant)

As you’ve been avoiding corn and soy, you can test it at the end of the program. If you want to test eggs, red meat, and nightshade vegetables, avoid them for say 2-3 weeks and then reintroduce them for two days, one at a time while eating only Clean Diet foods, to find out your reaction.

Lifetime diet

  • Fill 80% of your plate with greens and vegetables (raw, steamed, baked, cooked) and 20% with protein and good fats (meat, fish, avocado, etc.)
  • Stop eating when you are 80% full – this will help your body digest more easily
  • The Big Three – processed sugar, caffeine, and alcohol – remove dependency
    • Crowd out – eat good quantities of healthy food each day so you have less room for these foods
    • Pulse out – remove them from your diet for a period of time, so you can feel and remind yourself of the full effects. Do this regularly, for one week or one month
    • When you do eat these foods, enjoy them, and be aware of the present moment with each bite or sip
  • General food guidelines
    • Fruits and vegetables – purchase organic or chemical-free fruits and vegetables
    • Meat – purchase organic, pasture-raised, and grass-fed
    • Fish – purchase smaller, cold-water fish, such as listed above in the general what to eat guidelines
    • Eggs – purchase organic, free-range, and pasture-raised eggs
    • Grains – If you’ve reintroduced grains and found that they work for you, consider including nongluten grains in your diet, such as quinoa, millet, buckwheat, and rice
    • Oils and fats – look for organic expeller and cold-pressed, unrefined oils. Oils such as lard, coconut oil, and ghee are higher in saturated fats and better for high-temperature cooking. Olive oil is good for medium-temperature cooking but is best used in salad dressings or as a condiment. Nut and seed oils should not be used for cooking, instead use them in cold preparations
    • Nuts and seeds – look for raw varieties free of preservatives and sugar
  • Alternative eating habits to try
    • If you typically eat meat at most meals, take one weekend to go vegetarian. Then try it for one week. See how your body reacts
    • Once every month, for 2-4 days, go completely grain-free, both gluten and nongluten varieties. Or try removing grain for 2 weeks to see how you react
    • Try soaking grains overnight before cooking will make them easier to digest
    • Beans, lentils, and legumes can be difficult for many people to digest. Try soaking them first overnight to see if they’re any easier to digest
    • Nuts and seeds can often be difficult to digest – soaking them for a few hours can help. If you feel heavy after eating them, reduce the amount you include in your diet. If you frequently snack on nuts and seeds, try reducing your quantity and frequency to one handful every other day, and see if this improves your digestion
    • Try using coconut oil for one week – cook with it, use it as a skin moisturizer, and add it to your shakes and recipes
    • Try removing corn and soy for two weeks
    • Fruit takes the shortest time to digest and leaves the stomach within thirty minutes. When you eat fruit with protein or starches, the digestion of fruit can be held up and start to ferment in the intestines – it looks like the recommendation is to eat fruit separately from meals
    • Try adding probiotics – a cup of raw, unpasteurized fermented vegetables, kimchi, or sauerkraut each day to your dinner for a week. Or add low-sugar probiotic drinks. Also add small amounts of kefir made from goat’s milk or cow’s milk if dairy is not a trigger food for you
    • Try adding 1-2 servings a day of a fresh green juice or green smoothie for two weeks
  • Mind your food combinations and don’t food bomb
    • A food bomb results from mixing too many different types of food together in one meal, and often happens on holidays. Each type of food requires different enzymes in order to be digested, so mixing too many together at once causes poor digestion and creates fatigue
    • Eat nonstarchy vegetables and leafy greens with animal protein, grains, rice, legumes, and starchy vegetables
    • Avoid eating animal protein with grains, rice, or legumes
    • Eat fruit alone
  • Have a shake a day from the Clean Gut shake recipes

    I am doing the clean gut diet at the present moment, and I have one question the book said that we should eat 5 time a day but I don’t see what are the other food we can eat, the book only mention shakes lunch dinner but no shacks. I am using the nuts and berries as snack. I that ok?

    • Penny Hammond October 2, 2013, 7:33 pm

      Generally Dr. Junger refers to having 3 meals a day, some of which may be liquid meals. Could you let me know where in the book it says to eat 5 times a day?

      • Monica carroll April 13, 2015, 10:28 pm

        Chapter 7 – there is a section called “Mastering 5 Meals”

        • Penny Hammond April 14, 2015, 3:54 pm

          Thanks for pointing that out!
          This section talks about learning how to cook 5 meals that you prepare all the time, rather than asking you to eat 5 times a day.
          “The truth is that most people eat five to seven basic meals that they rotate seasonally. We may change the sauces, spices, and combinations, but the basic components of the meals are the same. Instead of getting wrapped up in complex recipes or the fear of eating clean for the rest of your life, focus on mastering five healthy meals. These five meals will be the base of your diet, the food you’ll eat most of the time.” (pp. 129-130)

  • Joyce October 5, 2013, 12:08 pm

    I would like to start this protocol but I have issues with most protein foods except beef, bison and elk meats. Ie. no nuts, soy, chicken, eggs, beans,etc. I have had reactions to “green”supplements ‘ probiotics and even magnesium. I’m afraid of taking pills of any kind as I react to many of them, esp. Antibiotics. Should I take it slow and introduce these supplements one at a time until I see how things go?

    • Penny Hammond October 6, 2013, 8:26 am

      Sorry to hear about all your reactions. It sounds like you really need this diet to heal your gut!

      This diet is asks you to eat mostly vegetables, 80% of your diet. For protein, it asks you to limit some of the foods you react to, like nuts, and avoid others, like soy and beans. If beef, bison, and elk work for you, use them as your proteins.

      Dr. Junger points out that each person is different so the best supplement programs will be tailored to your specific history and nutritional needs (p. 132). He recommends getting tested to see which supplements you need – if you’re extremely reactive it may be worth doing this to allow you to concentrate on mending nutritional gaps so your gut can heal faster.
      I concentrate on the food part of diets, rather than supplements, but for the supplements Dr. Junger lists on p.132 (which he says most people need), introducing them one at a time sounds like a good idea in your case.

  • Darlene May October 6, 2013, 9:03 am

    I have been on Dr. Junger’s program for one week now and have lost 9 lbs. I am absolutely thrilled with these results. I am not hungry all the time and I don’t have the food cravings in the evening. I believe this is the result of the elimination of sugar. I am having so much fun trying new recipes and have inspired my husband to join me. I feel fantastic both physically and mentally. What I plan to do is stick to phase 1 and skip phase 2. I don’t want to reintroduce food to identify my toxic triggers – foods that cause inflammation, acidity, irritation, or indigestion; also allergic reactions, food sensitivities, autoimmune reactions, mood swings, bloating, fatigue. I don’t ever want to feel any of that again. Thank you Dr. Junger for showing me the way.

    • Penny Hammond October 6, 2013, 9:20 am

      How wonderful that the results have been so good for you!

      While I understand that it’s an incredible relief to get rid of your symptoms, I suggest that you consider reintroducing foods to find out which ones are your personal toxic triggers. They aren’t the same for everybody. Eating just the phase 1 foods can be very limiting, especially socially, and you may be avoiding foods that are potentially healthful for you. It can also be empowering to know exactly which foods are your own personal toxic triggers – that allows you to concentrate your vigilance on your true enemies, rather than watching out for a very large group of foods you’re avoiding on phase 1.

  • Darlene May October 7, 2013, 10:52 am

    Thank you so much for your prompt reply. I will try introducing some foods, but will eat gluten free. I do have sugar issues and without the starches, I am finding things so much easier. I am scheduled for blood work next week and then I will find out from the doctor if there is any improvement.

  • TJ Eiford November 18, 2013, 11:26 am

    What about whey protein isolate?

    • Penny Hammond November 18, 2013, 5:56 pm

      Whey protein isolate is a dairy food, which should be avoided in phase 1 of this diet, and reintroduced only if dairy has been tested and passed.
      As it’s highly processed, it’s possible that this could cause issues – this diet recommends eating “real” foods.

  • Gloria December 8, 2013, 9:17 pm

    I have problems with excessive belching after eating, I never know for sure the triggers food since it happen with the same foods and sometimes it doen’t. Vegetables might be triggers, is better rosted or cooked than raw?

    • Penny Hammond December 15, 2013, 9:38 am

      Cooked vegetables may give you less belching than raw, as they’re often easier to digest. But the author of this diet suggests eating raw vegetables as well as cooked.
      Try chewing your food well, as this makes it easier for your digestive system to work on foods, and means you’re eating more slowly and possibly swallowing less air. Also try avoiding carbonated drinks.

  • Kim January 9, 2014, 12:10 pm

    I tried starting my program today and I am already so discouraged. I threw up the shake I made, creamy blueberry and I can’t seem to figure out why I am the only one to comment on the this? I have never tasted anything this awful in my life. I tried so hard to eat it. I am desperate to fix my health issues, but I don’t know what to do now. Any advice is appreciated. Thanks.

    • Penny Hammond January 9, 2014, 6:47 pm

      Sorry to hear that.
      What didn’t you like in the shake – the texture/thickness, or the flavor?
      Thickness – try adding more liquid
      Taste – try one of the other recipes (look to see if you like all the ingredients), or add an ingredient which you like the taste of (e.g. cocoa powder) that’s in another shake recipe, or substitute an ingredient that’s in another recipe, e.g. coconut milk instead of almond milk.
      You could also try drinking it slightly warm.

      Keep in mind that Dr. Junger suggests you vary the shakes so you’re not having the same foods all the time – try to find a few that you like.

    • Alison August 21, 2014, 12:04 pm

      Hi Kim, my daughter just called me with the same problem. I suspect that there’s a typo in the recipe. I think that the 1.5 cups of shredded coconut should really be coconut water or coconut milk. Hope you didn’t give up on the diet because of this.

  • Anna January 12, 2014, 6:06 pm

    Hi, I just read the book. Maybe it just went totally over my head, but what on earth are we supposed to do for lunch and dinner? I get the supplement protocol. Can anyone explain:

    For lunch, have a meal from the Clean Gut diet (guidelines aren’t clear) *****
    For dinner, have a meal from the recipes, consisting of an entrée-size salad *****

    For lunch, the guidelines AREN’T clear. I see the recipe section… are we supposed to just pick a recipe and have that? Where does the 80/20 come in?

    For dinner, have a meal from the recipes and make it INTO an entree-sized salad? Or, have a recipe from the recipe section WITH a salad? I am so, so very confused.

    Can anyone clarify this please? Thanks!

    • Penny Hammond January 13, 2014, 10:13 am

      In phase 1:

      Lunch should be “A meal from the Clean Gut Diet” (p.98) – this is what’s listed in the general “what to eat” section above – following the 80-20 rule, eating only permitted foods, and combining foods using the guidelines of which foods should be eaten together.
      As this doesn’t say you have to follow the recipes, you get a certain amount of flexibility in what to eat. Have a look at the recipe section – if you want to eat something from the recipes that meets these guidelines, go ahead, or you can create your own meal from the guidelines.
      The recipes in the book should all contain only permitted foods and combinations – it’s up to you to keep an eye out for having 80% of your plate filled with greens and vegetables.

      Dinner should be “A meal from the ‘Recipes’ section consisting of an entrée-size salad, plus supplements.” (p.98)
      It looks like you should be picking one of the salad recipes (pages 203-209), but that’s a very limited selection, only 7 salads. My assumption looking at the description and recipes is that you should have a meal that’s mainly raw salad, but that can contain a small amount of easily-digested protein such as salmon or chicken. If you want to go outside the strict guidelines of following the recipes section, you could use the salad recipes as guidance to creating new salads that meet the “what to eat” requirements.

      In phase 2:
      Follow the guidelines above for lunch and dinner, adding foods that you’re reintroducing.

      Hope that helps, let me know if anything isn’t clear.

  • Chuckwalla January 12, 2014, 10:48 pm

    Is tofu an acceptable food during the 21 day cleanse? It seems that it would fall into the vegetable protein category, but soy products were on the foods to avoid list.

  • Cathy P January 18, 2014, 4:59 pm

    Just wondering why fruits other than berries are not allowed during the 21 day cleanse. Also, are strawberries okay? They are not mentioned in any of the recipes so I’m unsure. Thanks!

    • Penny Hammond January 19, 2014, 12:01 pm

      Dr. Junger says “if you have an overgrowth of yeast, a frequent situation after antibiotic use, you may be throwing logs onto the fire. The sugar in fruit is on the list of a yeast’s favorite desserts.”
      Berries, lemons, and limes are allowed because they’re low-sugar. Other fruits are excluded during the cleanse to reduce yeast overgrowth.

      The only berry listed in the book are blueberries. Strawberries are usually considered a berry, and they’re not listed as “don’t eat”, so I assume you could eat them in moderation on this diet.

  • Lucy January 21, 2014, 9:22 pm

    I love the logic behind this program. Fix the gut and you solve a lot of problems. I am in week 2 and feel wonderful. I am also finding it easy to adhere to. But sometimes, I wonder if this book was quickly thrown together. I agree with a recent poster — the blueberry shake is inedible. It must be a mistake. And the shake options are very limited, esp. since Dr. Junger asks that you drink a green shake every morning. I’ve been drinking the shake with spinach, avocado, cashews and I’m totally over it. Wish there were more options.

  • Jen January 28, 2014, 3:14 pm

    This book was a life changer for me! I found that my primary migraine trigger is gluten, and dairy is also a headache trigger. I have completely eliminated them, permanently, from my diet. I believe 100% that leaky gut exists and is the source of more problems than I could have imagined. Had I not been so desperate to cure my headaches (I had a headache every minute of every day for three months with 2-3 migraines a week when I reached my desperation point), I would have never tried it – because I don’t ever have issues with my stomach, such as an upset stomach. Luckily, I found a holistic doctor, who explained leaky gut to me. I took it upon myself to learn more and bought the book. I did the strict 21 day cleanse even though (in all honesty) I didn’t like the shakes. Like some other posters, I drank the same one every day. I was sick of it by the end, but I toughed it out. I couldn’t tolerate the spirulina (headache!), but I did well with spinach. I also had some difficulty with a couple of the supplements and couldn’t take a few of them.

    I guess my point with all of this is, try as best you can to get through the 21 day cleanse, as written, but you also have to do what works for your body. Try to do it as closely as you can. If your body won’t tolerate something, that’s one thing, but if your tastebuds are giving you issues, push through…it’ll be worth it! My migraines are GONE. My headaches are SIGNIFICANTLY reduced. Most of the time, I am headache-free, but I am still getting one a day (working on finding the trigger). I have decided to stay gluten-free, dairy-free, mostly grain-free and refined sugar-free. I am trying to stay with the correct food combinations as well. I don’t miss any of the foods I have elminated because the other option is….headache!

    I have three friends now reading the book and their jaws dropped, as mine did, when they learned how it all comes down to your gut! 🙂

    • Penny Hammond January 29, 2014, 7:34 am

      Wow, what a relief that must be!

      For your only remaining headache, look at habits and situations that may be triggering it – which could be environmental, food, or stress. Dr. Junger covers environmental and other other toxic factors in his earlier book, Clean.

  • Shannon February 23, 2014, 8:44 am

    Are dates and date syrup acceptable snacks and/or sweeteners during the Clean Gut cleanse?

    • Penny Hammond February 23, 2014, 10:31 am

      Dates are fruits, and the only fruits allowed in the cleanse are fresh and frozen berries, lemons, and limes. Any other fruits, including dates, and any caloric sweeteners, including date syrup, are not to be eaten in phase 1 or phase 2.

  • Deborah February 24, 2014, 4:31 pm

    I will start the 21 day gut cleanse 1 march. Is marmite permitted?

    • Penny Hammond February 24, 2014, 9:29 pm

      The book talks about how “viruses, parasites, yeast, and pathogenic bacteria—or the lack of good bacteria, are associated with many more problems than we ever thought” (p.42). Many cleanses ask you to exclude yeast completely.
      There are a number of recipes in the book which contain nutritional yeast, but that’s a deactivated yeast. The main ingredient in Marmite is yeast extract – but I can’t find any clear guidance on whether it’s active or not.
      So… maybe try not to have Marmite during phase 1 or phase 2, but reintroduce it after phase 2.

  • Marla Sloan February 26, 2014, 12:10 pm

    Why are eggs included in the clean gut program and not in the clean program? In the clean program we were told not to eat eggs in phase 1. Why the change?

    • Penny Hammond February 26, 2014, 6:19 pm

      Dr. Junger lists eggs as a possible allergic or toxic trigger in Clean and Clean Gut. He also lists a number of other foods as not to eat in Clean but okay in Clean Gut (including chicken and meat). Generally, it looks like he’s assuming you’ve already followed Clean and already know your triggers – and avoiding them. Also, he’s advising eating pastured eggs and meat, which may have different properties than factory-raised equivalents.
      It wouldn’t be the first time a diet writer has changed their position over time as they learn more. But it could just be based on the assumption that you’ve already worked through the basic Clean and are ready for the next steps.

      • Adrian April 9, 2014, 2:10 am

        How can you and the author possibly assume one would have read the clean book before reading clean gut? That’s absurd and would want my money back. I’ve been following this program to the T for the last 28 days, reintroducing foods, etc, and haven’t found a significant change with any of my auto immune problems (I have a disease called dermatomyositis). I’ve spent almost 3000 dollars on food and supplements, changing everything out for organic and clean foods/spices, u name it. I’m going to continue testing foods, but even the program in itself, the foods it tells you to eat, u may have a food allergy to those as well!

        • Penny Hammond April 10, 2014, 9:56 am

          Clean Gut only covers food; there are often environmental factors which can trigger health conditions which is why Clean Gut won’t necessarily be effective on its own.

          You’re right, the program may not work for people who have allergies or intolerances to the recommended foods – however, these are foods that people tend not to be sensitive to.
          If you’re really interested in detecting your food allergies/intolerances in case it’s food rather than environment that’s causing your autoimmune problem, have a look at Food Allergies and Food Intolerance by Jonathan Brostoff – I used it many years ago to discover my own intolerances, it’s not exactly easy to do (especially if you tend to eat with other people) and it can take a while to test thoroughly, but it can really help pinpoint unusual triggers.

  • Sarah Aspinall February 26, 2014, 4:50 pm

    I have started the 21 day cleanse in the clean book. So far so good. The creamy blueberry shake on page 248 was impossible to make. I have a Vitamix. Is it 1.5 cups coconut or coconut milk? It says coconut but there is no liquid so I added water to be able to mix it. Was that a typo?
    Also is the clean gut book much different? I have both. Should one do the clean cleanse first then the clean gut or what is suggested. Thank You
    Looking forward to seeing what happens on the cleanse.

    • Penny Hammond February 26, 2014, 6:12 pm

      There’s nothing in Dr. Junger’s website to show errata in the book, but it sounds like that’s one of them (it was also pointed out by a reviewer on Amazon). Looking at the ingredients, that would make an extremely solid shake! You could try with coconut milk or coconut water, similar to the other recipes.

      The author suggests trying Clean first – it has much more than just dietary advice, it claims to help you to reduce toxins in your whole environment. Clean gut is the “advanced” course focusing on diet alone.

      Good luck with the cleanse!

  • Grace March 3, 2014, 10:52 am

    Does it matter what your blood type is?

    • Penny Hammond March 3, 2014, 11:45 am

      This book doesn’t talk about blood types at all.

      The most popular book on diet and blood types is Eat Right 4 Your Type by Dr. Peter D’Adamo.

  • Ericca March 6, 2014, 11:12 am

    I am a vegetarian but I know I eat way to many processed foods and that it’s causing health issues. My only question is can you get sufficient protein when eating only a side of quinoa, lentils or split peas per day? Thanks so much for a great synopsis of the book and great responses to the questions people have asked here.

    • Penny Hammond March 6, 2014, 12:19 pm

      If you can eat eggs, they’re allowed on this diet (organic or pasture-raised).
      Bee pollen, spirulina, and blue-green algae are also listed as vegetarian proteins, as are vegetarian protein powders (rice protein powder, hemp protein powder, and pea based protein powder).
      Don’t forget that nuts and seeds contain protein as well.

  • Angelina March 10, 2014, 10:13 am

    I am hoping to start this programme in a weeks time. However I am really going to struggle with having a meal for lunch. So I am going to have to have a shake for lunch and then the meal for dinner. I know this is not the programme but it’s the only way I’m going to be able to do it. Will it still have the same health benefits? Thanks

    • Penny Hammond March 11, 2014, 6:04 pm

      That’s probably fine – I can’t see anything in the book about letting your digestive system rest for long periods of time, which might be a reason for having the green smoothie at breakfast instead of lunch.

  • Kristin March 13, 2014, 1:52 pm

    Thank you for a wonderful summary on the book and the cleanse. Are you supposed to continue the supplements during phase 2 as well or take them only for the 21 days during phase 1? Thanks again!

    • Penny Hammond March 16, 2014, 10:39 pm

      I’m glad you find this helpful. Unfortunately I only concentrate on the food side of diets, not supplements…

  • Maria March 16, 2014, 3:26 pm

    My boyfriend and I are going to start this diet soon! We cannot afford $800 for the supplements/program…there is a health food store in town…would it be all right if we bought the supplements locally?

    • Penny Hammond March 17, 2014, 8:05 pm

      I concentrate on the food side of diets, and don’t really look into the supplements. Try reading the recommendations in the book and finding something that matches them closely enough.
      Good luck with the diet!

    • Kristin April 28, 2014, 2:01 pm

      Hi Maria,
      Yes, that should be fine as long as you find supplements with the correct dosage as outlined in the book. That’s what I did (I got all of my supplements from The Vitamin Shoppe) and only spent ~$130 total on them. Goldenseal is a good choice for the herbal supplement that you’re supposed to take twice a day. Good luck!

  • cindy smith March 22, 2014, 2:09 pm

    I am on the third week of the program, and SICK of the smoothies. Can hardly get them down. But I am wondering about the tea. Book says herb tea, what is wrong with instant tea?? And WHAT is a green juice?

    • Penny Hammond March 23, 2014, 3:27 pm

      Instant teas often contain artificial additives and preservatives – you’d have to be careful to find one where the only ingredient is herbal teas.

      A green juice is what you get when you juice green vegetables without any fruits or non-leafy vegetables.

  • JC March 22, 2014, 2:25 pm

    Pls. Is there anything else I can drink or eat in morning besides those shakes? I’ve thrown up every morning and tried everyone. 🙁 Thank you.

    • Penny Hammond March 23, 2014, 3:25 pm

      Sorry, but the shakes are the only alternative that the author gives for breakfast! As well as the recipes in the book, you could try the ones http://www.cleangut.com.

    • Maria June 18, 2015, 7:35 am

      You probably need to ease into the diet slowly. You’re gut health seems like it’s in a pretty bad state if you can’t stomach blended vegetables. Try an elimination diet first for a week where you simply avoid all the food allergens and junk, but continue to eat three meals a day.

  • M Craig May 15, 2014, 1:49 pm

    If you can’t drink the shakes, how about deconstructing them — can you just eat a cupful of raw spinach and half a cup of blueberries and drink a glass of unsweetened almond milk?

    • Penny Hammond May 15, 2014, 8:20 pm

      Dr. Junger doesn’t explain in this book why he thinks you should have shakes; there’s some discussion of detox diets in his first book, Clean, where he talks about different types of detoxes which may include shakes. Some discussion points – the fiber is released in shakes and grabs toxins in the intestines so they don’t get reabsorbed; or they’re an easy way to deliver a number of different nutrients. Other diet books talk about giving your system a rest so it doesn’t have to work so hard to digest.

      If you really hate the shakes, you could try deconstructing them, making sure you chew really well.

  • Nieves June 15, 2014, 1:40 pm

    Thank you for a great summary on the Clean Gut Diet Penny, it has clarified a few doubts I had after reading Dr. Junger’s book.

    The diet guidelines indicate to go easy on the allowed Legumes (split peas, lentils) as well as quinoa, only a side serving a day. My question is: How much is a side serving of split peas, lentils and/or quinoa?

    In addition, would you have any suggestions for green juices?

    Thank you again!

    • Penny Hammond June 19, 2014, 6:02 am

      Glad to help!

      I can’t find any guidelines for portion sizes for the allowed legumes and quinoa – Dr. Junger just reminds you to go easy on them. Perhaps about 1/2 cup total maximum per day?

      The book asks you to have fresh green juices, which would mean they’re made from scratch. The Healthy Green Drink Diet book by Jason Manheim has a number of green juice recipes – watch out that the ingredients are allowed on this diet, as there are a number of smoothie recipes that have fruits that wouldn’t be allowed.

  • Lisa Brown July 9, 2014, 4:21 pm

    Looks like a great program, but I am concerned about the protein and fat intake daily.

    I cannot digest, red meat, poultry, wild game, anything but fish, for some reason. I eat fish and eggs mostly, daily, but I also have to watch my fish and egg intake as I have very high levels of B12 (just recently checked) so I must watch how much B12 I take in a day. I don’t always eat the yolks in eggs because I am trying to keep the B12 minimized until the level returns to normal, so I eat the egg whites, with the occasional yolk (maybe 4 times a week). I don’t see any other protein sources I can eat. Also, I do not digest fats well. I have to limit fats or my digestion is effected. My current tests say my gallbladder/liver is fine. With these “leaky gut” types of diets, I don’t see, with my limits on fat and the protein sources that I can eat, that I can get enough food, and calories into me daily without starving. Not sure what to do.

    • Penny Hammond July 10, 2014, 5:32 pm

      Wow, that’s tough. There’s a lot of information out there about low vitamin B12, but not much about what to eat if you have high vitamin B12. The most helpful resource I found was http://ods.od.nih.gov/factsheets/VitaminB12-HealthProfessional/.
      Has your doctor given you guidelines about how much vitamin B12 you can eat, or just asked you to limit it?
      Do you know what the underlying condition is that’s causing the high B12, to look for specific dietary guidelines for that condition? It looks like most people can eat unlimited amounts and it’s flushed out of the system, so maybe it would help to understand what’s causing the high levels.
      It could be that, for you right now, more starchy protein sources such as grains and legumes might be a better source of protein and energy. That’s not this diet, you’re correct.
      Hope that helps a little bit.

  • Marisol Brugmann July 26, 2014, 11:56 am

    On page 124 of “Clean Gut” it says ” Higher quality coconut oil will have less coconut taste. Check out cleangut.com
    for our favorite brands.” Have not been able to find it at cleangut.com
    Would love to know what oils are recommended.
    Thank you.

    • Penny Hammond August 4, 2014, 6:46 pm

      I can’t find anything on cleangut.com or cleanprogram.com on recommended brands of coconut oil; the only mention I could find was in the Clean Gut blog presale page, where Nutiva coconut oil is mentioned. That doesn’t mean that it’s the only one recommended; apologies for not being able to find any more!

  • Suvi July 29, 2014, 1:22 pm

    Hi, my husband and I started the program two weeks a go. We followed the instructions strictly the whole time. Now my husband is going fine and he lost 5,5 lbs. How about ME? I gained 2 lbs, felt awful all the time! What on earth did happen and why? Also my stomach swelled and I felt very full 24/7. We both are quite of normal weight but wanted to lose some.

    • Penny Hammond August 4, 2014, 7:29 pm

      How annoying!
      Did you chew your food really well? Sometimes, if you’re not used to eating a particular food, you swallow it as quickly as possible without chewing it and that makes it more difficult to digest, which can lead to bloating.
      Also, was there anything you snacked on or ate a lot of?

  • Sunny August 9, 2014, 11:31 am

    I read the book in Korean verision and then have just started the program.
    In the Korean book, there is a saying that strawberry kiss smoothie(from smoothie king) can be substitute for cleangut shake.
    I am wondering that there is natural fruitsugar in the smoothie. Is it possible to drink ?

    • Penny Hammond August 10, 2014, 8:42 am

      A couple of the shakes in the US version of the book contain small amounts of blueberries, which are a low-sugar fruit – and also a number of other ingredients, including dark leafy greens and nuts/seeds. Strawberries are generally considered to be a low-sugar fruit – if the smoothie you’re talking about has only a small amount of strawberries and contains lots of dark leafy greens and some nuts/seeds, it might be okay on this diet.

  • Georgina August 14, 2014, 1:31 pm

    Gosh! I can tell I will find this difficult to stick to! But I totally want to give it a go! Even if I only start eating 40% better i’ll be so so happy with the results! Thanks for the extensive information.

  • Jenny September 17, 2014, 5:33 pm

    I was wondering if you could help me with something im a little confused about.. I once read you shouldnt pair 2 proteins, competing proteins.. I often have quinoa and veggies for lunch but i sometimes add pumpkin protein powder for some added protein.. Do you think this is a bad combo? I see you consider quinoa a vegetable protein.. Do you think pumpkin protein powder is also a vegetable protein? Which would make it ok? I hope so because its one of my favorite lunches! 🙂 but i recently am concerned with food pairings for better absorbtion and nutrition.. Thank you for your help!

    • Penny Hammond September 17, 2014, 6:37 pm

      Dr. Junger says that you shouldn’t pair animal protein and vegetable protein in the same meal – he doesn’t say anything about combining different animal proteins or different vegetable proteins (and I don’t think I’ve heard of combining proteins being a issue with any other combining diets I’ve read about).
      Quinoa is a vegetable, and pumpkins are a vegetable, so the proteins in them are both vegetable proteins – it shouldn’t be a problem to combine them on this diet. However, it may be even better to have pumpkin seeds instead of pumpkin protein powder – they’re an unprocessed, whole food (pumpkin protein powder is processed from pumpkin seeds, which are the part of the pumpkin that contains the most protein).

  • Mi Mi October 13, 2014, 7:30 am

    Hi .I’d like to start the program but I’m not interested in losing any weight. Your thoughts please?

    • Penny Hammond October 13, 2014, 9:55 am

      The book isn’t about losing weight, although losing weight might be a by-product of the process. It’s about eliminating the root causes of disease – the author says that the root of almost all chronic diseases starts in your gut.

      So you can follow the program even if you don’t have any weight to lose.

  • Jamie Berndt October 26, 2014, 3:49 pm

    Are we able to snack on this plan? On veggies or berries? I don’t see snacks mentioned in the book, but I also do not see them expressly prohibited.

    • Penny Hammond October 30, 2014, 9:51 am

      The books says you can “have a clean snack” (p.143).
      Veggies and berries should be fine.

  • Jo December 14, 2014, 9:19 am

  • Ruth December 19, 2014, 2:10 pm

    Yacon or Lakanto?

    I thought yacon was one of the allowed sweeteners when I did Clean Gut last January, but now I am seeing Lakanto as one of the three and no mention of yacon. Is yacon ok?

    Thank you!


    • Penny Hammond December 26, 2014, 1:21 pm

      Hi Ruth,
      Yacon is listed in the original Clean book, and in this list of sweeteners that are okay to eat in small amounts: http://www.cleanprogram.com/media/files/elimination-guide.pdf.
      However, it isn’t listed in the Clean Gut book, which was written later. Not sure if that’s because Dr. Junger decided it’s not as good for you, or he was promoting other sweeteners, or it just got left off by mistake.

  • Muris December 20, 2014, 7:27 pm

    Hi, i have been following this kind of diet for couple of months now but now seem to have developed some kind of severe histamine intolorence that i cannot have meat unless very fresh without causing problems. What would you base your meals around and to get some protein? Ive been mainly having vegtable stews with rice protein shakes and nuts as snacks as well as green juicing, however now im finding nuts and grains are irritating the gut also 🙁

  • Sunny December 23, 2014, 11:22 am

    I did the clean gut program last August. It was great for me! However, I couldn’t endure my stress during Nov~early Dec, I had a lot of snacks for reducing my stress.. So I’d like to try this program again. Is it okay? I mean it would be no problem with my guy if I do it 2 times a year. Should I take all the supplements again?

    • Penny Hammond December 26, 2014, 1:56 pm

      Hi Sunny!
      Sorry to hear you were so stressed for the past couple of months.
      How far through the program did you get – did you do any phase 2 reintroduction of foods to see how your body reacts to them? How do you feel in general now – do you think you’d benefit from going through the cleanse again, or would you feel comfortable moving straight to the lifetime diet?
      If you already tested foods and saw they were okay, and you want to do the cleanse again, you could probably add the tested foods to the phase 1 foods.
      I concentrate on foods, not supplements – if you feel that it’s worth doing the full cleanse again, maybe the supplements would benefit you.

  • Marisol B December 29, 2014, 12:30 pm


    I’m about to start the program! I already bought the supplements, but I was wondering which other brands of protein powder did you use instead of the Clean Shake? Thanks!

    • Penny Hammond December 31, 2014, 1:37 pm

      Dr. Junger suggests a plant-based protein, but he doesn’t give alternate brands (of course he’s trying to sell his own brand).

    Hello and Happy New Years!
    Well it has begun. The quest for a healthier me. I am a sufferer of autoimmune disease. I have chronic uticaria and angioedema. I also have been having issues with random stomach issues (getting sick). So. I am done. I am only 47 years old and am shattered that I have become like an old lady internally. I have heard from many sources that trying a clean diet might be the way to go for me. This of course has not been a suggestion from my physician. He sadly scoffs at such healing ideas. I purchased the Clean Gut diet book. I am very excited to try it. Any suggestions?

    • Penny Hammond January 4, 2015, 2:59 pm

      Happy New Year to you too!
      I suggest you keep a food and symptom diary to see how you’re doing. At the beginning you may have some worse symptoms, especially if you’re used to eating a lot of processed foods, sugar, or caffeine. But after detox symptoms go away you may start to feel better, although it might not happen straight away. Good luck.

  • sarah January 8, 2015, 3:00 am

    Hi Penny- are fresh prawns allowed? Also, store bought almond milk- what ingredients are allowed? I’m having terrible trouble finding clean approved almond milk. Thanks very much! Sarah

    • Penny Hammond January 10, 2015, 12:36 pm

      Hi Sarah,

      Whenever Dr. Junger mentions seafood, he talks about fish but not shellfish. He doesn’t say to avoid shellfish… but they’re often contaminated so that might be why he doesn’t list them as okay to eat.

      Have you ever thought about making your own almond milk? Search the internet for “almond milk recipe” or whichever one you want to make.
      Generally, you grind the nut and add to water and blend well, or put nuts and water in a blender and blend well, then strain the mixture.

      • sarah January 12, 2015, 12:10 am

        Thanks very much Penny- this page has been very helpful! 🙂

  • Lisa Brown January 12, 2015, 9:38 am

    Hi, there.

    The cleanse calls for an herbal anti-microbial and I saw the one recommended, Tricycline which is over $40. Is there a less expensive option out there? I have been looking around and can’t find many of this type of supplement, a blend. Can one just take Berberine? Thank you and happy new year 🙂

    • Penny Hammond January 12, 2015, 8:17 pm

      Hi Lisa, and happy new year to you too!
      I look at the food side of diets, and I don’t know about the supplements. Can anybody else help?
      You could try checking in with the coaches (they say this is a free service) – http://www.cleanprogram.com/coach

  • Christina January 27, 2015, 3:13 pm

    Question: The book calls for using coconut milk, but it doesn’t say what kind. The canned variety or the kind in the carton? If it’s interchangeable with almond milk, I’m assuming it’s the kind in the carton, but it’s not clear.

    • Penny Hammond January 27, 2015, 4:03 pm

      Dr. Junger says “You can use canned coconut milk, but it’s very rich and some brands may have additives. Read the ingredients and, when in doubt, make your own. You can also use coconut milk in a carton from the health-food or grocery store. Make sure it’s unsweetened.” (p.159)

  • Saul February 10, 2015, 5:02 pm

    OK day 2 so far so good

    quick question
    in the Clean Gut diet it says no caffeine or caffinated beverages

    but it also says you can drink green and white tea (both of which are caffinated)
    and yerba Mate ( caffinated)

    as a coffee drinker, I’m looking for a milder solution than cold turkey
    with this part, can anyone help a brother out?


    • Penny Hammond February 13, 2015, 2:27 pm

      You’re correct – green tea, white tea, and yerba mate are listed in the “Clean Gut Diet Food List” (p.95)
      It could be because these teas tend to have a lower level of caffeine than coffee or regular tea. See the mg/fl.oz. column at CaffeineInformer (click on Coffees or Teas to see the data).
      Or it could be because they have other beneficial compounds that offset the caffeine.
      Or it could be that when Dr. Junger said “avoid caffeine” he meant “avoid coffee and caffeinated soda.”

      Would one of these teas work for you as a substitute for coffee?

  • Ankyspondy March 25, 2015, 10:17 pm

    What is the rational for avoiding barbecue sauce, chutney, ketchup, relish, traditional soy sauce, teriyaki sauce?

    I am asking because I do find that I react to these foods but I cannot figure out why!


    • Penny Hammond March 26, 2015, 3:45 pm

      Barbecue sauce, chutney, ketchup, and relish (as well as teriyaki sauce) tend to be loaded with sugar, and sometimes added chemicals. This is a no-sugar diet.
      Soy sauce and teriyaki sauce contain soy, and this is a no-soy diet until you’ve tested it to see how you personally react to it.

  • Joel Diemer April 6, 2015, 10:12 am

    I am about to start this program – primarily because most of my maternal aunts and uncles died of colon cancer. However, I am working with a highly qualified trainer with the goal of gaining back 15+ pounds of muscle mass – lost during two years of recovery from a badly smashed elbow. Despite extensive searching I’ve found nothing of consequence that advises how to use the program to gain weight. Suggestions?

    • Penny Hammond April 12, 2015, 11:46 am

      The book has an analogy to growing a tree – keeping the roots healthy is the key to tending the whole plant, and making your gut healthier allows your whole body to improve.

      So you could try to use this program as the basis for health, and take learnings from other places on how to increase muscle mass as long as they also meet the guidelines of the diet.
      Perhaps you could be patient and go through the full 28 day program to make sure the basics are in place, if you can work with 20% protein in your diet for a month. Then focus on testing proteins to see which ones are healthy or toxic for you. Once you know which proteins are healthy for you, use them moderately along with exercise to gain back your muscle mass. Does that help?

    Your guidelines are good and helpful to summarize the program. Me and my husband have been on this program for a bit over a week. we are following it loosely, we stayed away from all grains except Quinoa, dairy, and other suggested foods to avoid but we do our own smoothies made with berries and sometimes coconut flesh, sometime hemp protein, sometimes vega, we just check the ingredients on any shakes. Also we are vegetarians, i do not eat eggs or any kind of meat or seafood. i was diagnosed with yeast overgrowth recently, and was treated for it, but it did not go away completely. i felt sick for the entire first week and had a few good days, my husband’s headaches have gone worse, he craves coffees and some of his other older health issues have returned. My yeast overgrowth also returned after following program for about a week or so. i found this book guide for eating foods and a section dedicated to vegetarians, http://www.cleanprogram.com/media/files/gut-sample-meal-plan.pdf
    which i don;t recall being in the book. After doing some of my own research, I have increased my coconut oil consumption significantly (try to get 4-5 tbspoons), and feel a relief,

    I am Vegan and desperately want to try this. I felt like I had a successful first day and then I realized the “nigh shades” are not permissible. If I include tomatoes and peppers do you think I should still get the benefits of the change? I have experienced nausea for 10 weeks and have had every test (all negative), medicine, and even accupuncture. I am really hoping I can get relief from this.

    • Penny Hammond June 7, 2015, 12:10 pm

      Dr. Junger is a little contradictory about nightshades on this program. He includes tomatoes in the Clean Gut Diet Food List (p.95), so he’s not saying you have to avoid nightshades during the program. However, on p.107 he lists nightshade vegetables (potatoes, tomatoes, peppers, eggplant) as one of the most common toxic triggers and suggests that you test them separately. So try this: include them in phase 1, and see how you feel. If you’re still not feeling good after following the food list for phase 1, try also avoiding nightshades to see if that helps (you don’t have to wait the full 21 days for this – try after following phase 1 for 1 week). Then reintroduce the foods as suggested.

      Also, try looking at Dr Junger’s other book, Clean, to see if any non-food toxic triggers might be affecting you.

      Hope that helps, and hope you feel better.

    I’ve been working on clean gut. Why should beet be avoided for clean gut?

    • Penny Hammond July 24, 2015, 6:50 pm

      Beets are a high-sugar vegetable – the sugars are natural, but the program is low sugar (including natural sugars) so they should be avoided.

  • Sheney August 17, 2015, 1:48 pm

    Hi Penny
    All your comments and feedback is really so helpful – thank you!
    I wanted to ask – I have not been diagnosed with PCOS but have a strong feeling that I may have this, as I am experiencing some of the symptoms. At the same time I want to follow this program. Would you say that following a clean gut diet will automatically help with PCOS symptoms or should I be following a PCOS diet? So unsure of what to do first 🙁
    Thanks so much,

    • Penny Hammond August 23, 2015, 4:19 pm

      Hi Sheney,
      How about trying the Clean Gut diet first and seeing how it clears up your symptoms? It’s possible your symptoms might go away and there won’t be a need for a separate PCOS diet.

  • SL September 1, 2015, 4:02 pm

    I am on a daily antibiotic related to frequent UTIs and kidny stones. I’ve been on them for years and have been gaining 6+ pounds a year because of the gut problems it has created. Is there anything I can do to improve my gut health while continuing on antibiotics?

    • Penny Hammond September 2, 2015, 7:05 pm

      Wow, that must be really frustrating.
      The book doesn’t contain any guidelines on how to improve your gut health while continuing on antibiotics.

      Are daily antibiotics the only way to deal with the infections?
      The book appears to argue that improving your diet according to its guidelines will help you to improve your general health, lowering the likelihood of infections and other health issues.

  • scrittitrader October 3, 2015, 3:28 am

    I see that yeast in the gut is a problem, so I’m wondering why nutritional yeast is allowed on this program during phase 1? Any thoughts on this?

    • Penny Hammond October 5, 2015, 12:47 pm

      There are many different types of yeast – perhaps nutritional yeast doesn’t have the negative effects that some other types of yeast have.

  • Mar October 11, 2015, 10:59 pm

    Hi Penny, thanks for your post
    I am wondering when and how to introduce all fruits (and all others non toxic triggers foods) after the 3 weeks + 1 week, in the clean gut program?

    • Penny Hammond October 25, 2015, 3:49 pm

      Hi Mar, glad to help!

      I can’t find any guidelines in the book on how to reintroduce non-toxic foods. It tells you to fill 80 percent of your plate with greens and vegetables (raw, steamed, baked, cooked) and 20 percent with protein and good fats (meat, fish, quinoa, avocado, etc.) – but not how to fit in any other foods.
      It’s not entirely clear, but perhaps fruits and starchy foods should be considered as treats to have occasionally, rather than major components in meals.

      Regarding fruits, Dr. Junger says that “fruit takes the shortest time to digest and leaves the stomach within thirty minutes. When you eat fruit with protein or starches, the digestion of fruit can be held up and start to ferment in the intestines” (p.127) – it looks like the recommendation is to eat fruit separately from meals.

      If you think you might react to specific foods, such as beans/legumes, try introducing them separately from other foods to see whether/how you react to them.

  • Venkat October 14, 2015, 2:19 am

    Are these fruits allowed?
    Banana, pomegranate (berry family), strawberries, raspberries allowed in this program?


    • Penny Hammond October 25, 2015, 4:15 pm

      The only berry listed in the book are blueberries. Strawberries and raspberries are usually considered a berry given their sugar level, and they’re not listed as “don’t eat”, so I assume you could eat them in moderation on this diet.
      From the USDA National Nutrition Database, sugars per 100g:
      Blueberries – 9.96g
      Strawberries – 11.34g – might be borderline for this diet
      Raspberries – 4.42g
      Blackberries – 4.88g

      The botanical definition of berry is a certain formation of fruit – “True berries are simple fruits stemming from one flower with one ovary and typically have several seeds”… and include bananas, kiwis, tomatoes, and pomegranates (Stanford Alumni magazine)
      Pomegranate – 13.67g – higher sugar than foods commonly described as “berries”
      Banana – 18.34g – a high sugar fruit

      This book appears to be referring to berries in the common definition, rather than the botanical definition, so banana and pomegranate wouldn’t be allowed and strawberries may be borderline.

  • Debbie Cox January 17, 2016, 7:10 am

    I am into day 3 of the clean diet as I have atrophic gastritis and want to heal my tummy. I am already a small build and concerned about losing weight without all the carbs and grains. Should I be having shakes or protein balls between the main meals to keep up energy levels and add some calories. I also like to exercise as a cyclist and doing resistance training. Should I modify some of the rules of this diet to suit my body build and energy levels?

    • Penny Hammond January 17, 2016, 7:58 pm

      There are plenty of non-grain carbs listed as foods to eat –
      Vegetables: acorn squash, butternut squash, carrots, kabocha squash, parsnips, pumpkin, spaghetti squash all have a good amount of carbs, and onions and tomatoes also provide carbs.
      Pseudo-grains: quinoa (in moderation)
      Legumes: split peas/lentils (in moderation)
      Nuts: also give you carbs, protein, and fat (in moderation)
      Can you use these to give you the energy levels you’re looking for?

      If you want to make shakes or protein balls, make sure they fit the guidelines of what ingredients to eat and quantities.

    Hi, I have read a bit about beneficial gut bacteria needing resistant starches for survival and reproduction. I am wondering if Dr Junger has recommendations of what types would be acceptable on this diet. I have read that low carb diets often don’t support the beneficial bacteria for this reason. Thank you

    • Penny Hammond February 29, 2016, 6:59 pm

      Dr. Junger doesn’t say anything in his book about beneficial gut bacteria needing resistant starches for survival and reproduction. However, he includes a lot of vegetables in the diet, which have their own starches.

  • Holger March 13, 2016, 10:23 am

    I have started the 3-day Jumpstart Cleanse but am a bit concerned about the interaction with some of my prescription drugs with Berberine, so I have omitted Berberine from the program.

    Is it safe to take Berberine with Tambocor (an anti-arrhythmic drug for the heart – contains Flecainide)?
    Is it safe to take Berberine as an asthmatic?

    • Penny Hammond March 22, 2016, 5:25 pm

      Thanks for your question, but I focus on the food side of diets and don’t know enough about supplements to answer. Also, this post is for the Clean Gut book, not the 3-day jumpstart cleanse, which I haven’t looked into. I hope you find the answer somewhere else!

  • Kim Jackson April 11, 2016, 2:21 pm

    Clean Gut diet- when looking at the elimination 3 wk diet- does one focus on the “do NOt Eat” list and focus on that. Trying to eat mostly foods on the do Eat side but what about foods not listed on either? can they be eaten in moderation? Man thanks

    • Penny Hammond April 17, 2016, 10:09 pm

      For any foods you don’t see listed, see whether they fit better with the foods in the “eat” or the “don’t eat” lists. E.g. a non-starchy vegetable would be “eat” and a starchy vegetable would be “don’t eat”. A processed food would be “don’t eat”. Hope that helps.

  • Rose Marie A. Klavon May 4, 2016, 4:44 pm

    I thank god for Dr. Junger’s book, Clean Gut. Everything about this program is great. I have one question; when making smoothies, can I make extra servings and store in the refrigerator for the next days?

    • Penny Hammond May 22, 2016, 4:21 pm

      I can’t find anything specific in the book about whether you have to drink the shakes straight away or can store them. However, for recipes that can be stored, the author will often say so (e.g. Basic Nut Milk, “Store in the refrigerator. The milk will keep for three to four days.” Also, once you blend the ingredients they start to decay ever-so-slowly, so the shakes wouldn’t be as effective if you store them in the refrigerator for a few days vs drinking them fairly soon after making them. They also might not taste as good.

  • Kathleen M Owen May 20, 2016, 3:07 pm

    can I eat popcorn?

    • Penny Hammond May 22, 2016, 5:46 pm

      Dr Junger says that you should avoid corn on this diet, and popcorn is made from corn so I’d assume you can’t eat popcorn on this diet.

  • Tom Nelson November 9, 2016, 5:58 am

    Hey Penny,
    I would like to know if it’s okay to consume pure 100% cocoa powder?

    • Penny Hammond November 25, 2016, 12:52 pm

      Hi Tom,
      The book says you should avoid regular chocolate (with dairy and sugar).
      In most of the recipes it asks you to use either cacao powder (which is basically the same as pure cocoa powder but raw, and is said to contain more ingredients), or carob powder.
      However, there is one recipe (Chocolate Ginger Shake) that gives the choice of raw cacao powder or cocoa powder.
      It looks like the author would prefer you to use cacao powder (which you can get online or in health food stores), but maybe having pure cocoa powder occasionally would be okay.
      Hope that helps!

  • S.Hamilton November 23, 2016, 3:02 pm

    Headaches; Have you tried stopping any form of sugar replacements? Including Stevia, xylitol, Lakanto, all which are ok on the list but personally effect me. Any kind of sugar replacement gives me blinding headaches. Blinding. This diet kills most of those so IF that happens to be the problem that might be why this helps. Worth checking into by charting the headaches and these replacement sweeteners, if you are using them.
    Good luck and I hope you find it soon!

  • Kasey January 16, 2017, 5:24 pm

    Why would quinoa be okay but not brown rice? And why lentils but not beans. Every candida/gut diet I see is different. I understand grains are probably best avoided but why not just eat a tiny bit? Many candida diets allow that too: i am so confused 🙁

    • Penny Hammond June 20, 2017, 8:00 pm

      It’s only short term, hang in there! These are foods that will be reintroduced later on to see how you react to them. It’s more common to react to those foods. When you take a break it makes it easier to recognize your reaction.

  • Becky Johnson March 4, 2017, 2:04 pm

    I will be starting the gut cleanse program on Monday. I am prepared to do significant meal prep to make this successful, but as a full time working teacher and mom, I am having a hard time wrapping my brain around preparing the suggested lunches when I only have 30 minutes to eat lunch (on a good day). The dinner salads would be much easier to prep and pack for lunch. And, the lunches would be much more practical time wise and ingredient wise for myself and family to eat for dinner. Can I switch lunch and dinner and achieve the same results?
    Thank you!

    • Penny Hammond June 20, 2017, 8:01 pm

      Sure, that should work.
      Good luck!
