The 3 Phases of the Lean Gut Diet

The Lean Gut Diet guide may be overwhelming to readers, which is why it is broken up into 3 phases.

Phase 1

In this phase, you will learn what foods should be avoided to promote healthy digestion. You will not be required to eat less; in fact, you will be encouraged to eat more. The guide will reveal to you which foods must be avoided at all costs and what you need to know before choosing from a variety of fruits and vegetables. You will also learn how to make the delicious Eliminator Elixir – a recipe that will undoubtedly become a staple in your diet.

Phase 2

This phase is all about restoring the perfect balance between the “good” and “bad” bacteria in your gut. You will learn which carbohydrates should be included in your diet. At this phase, you will also be introduced to a list of 7 probiotic foods that can be added to daily meals to improve digestive health.

mind-stress-freePhase 3

The last phase focuses on reducing the level of cortisol, a.k.a. the stress hormone, in the body. With 3 simple rules, you will be able to minimize your stress level, improve mental health, and boost your metabolism. This phase also includes all the science and evidence to support the three phases of the Lean Gut Diet.

Also included in the guide are two bonus reports:

Bonus #1: 10 Best Metabolism-Revving Foods to Turn Your Body into a Fat Burning Machine

Bonus #2: Sex Food Stimulants

The Lean Gut Diet will not show you results overnight. The process of correcting bacterial balance in the gut may take several weeks, depending on the individual. However, after a few days of following the guide created by Samuel Larson, you will notice changes in your mood and energy. After a few weeks, you will see significant weight loss and improvement in health.

Informative, interesting, easy to follow, and most importantly - very helpful.

Lean Gut Diet - Results are Real!


To be honest, I didn't expect much from this e-book other than just some theory on how I should be eating. I still wanted to get it so that I could become more informed on how digestion works and what I could do to improve it and hopefully lose some weight.

After reading the e-book, I started following parts of the advice, and not very strictly. Even so, I noticed some differences after only 2 weeks of doing this! Today, I follow the advice quite strictly, and believe me - it's worth it. Overall, I lost 8 inches around my waist in 2 months - a slow, healthy change.

I highly recommend anyone to try the Lean Gut Diet, whatever your goals are. It definitely can't hurt!

Pleasantly suprised


I was recommended this e-book by my friend. I decided to give it a shot even though I usually hate e-books that sell tips or advice. However, I was pleasantly surprised by the Lean Gut Diet. All the information is well-presented and easy to understand. I learned a lot from the book and try to incorporate the suggestions into my lifestyle. It's not easy, but I feel the difference even with small changes. I highly recommend it.

Why it's so hard to lose weight - and how to achieve it


The e-book is very informative and I have learned a lot from it. A friend recommended it to me and I see why - some of the tips in here really make the difference for your body.

One thing I would improve is add more recipes that are consistent with the diet's recommendations. I feel like I might begin to run out of ideas on how to use the super ingredients in various meals.

The Lean Gut Diet Works


I've only been following the Lean Gut Diet for 2 weeks but I already feel better about myself. I didn't even realize that I had symptoms of an unhealthy gut until I experienced what 'normal' should feel like. The diet works! I am definitely keeping it, and I can't wait to see what's next.

Good and Unique


The e-book is interesting and unique. I have read some other books on digestion diets, and some of the details here were new and made a huge difference in my nutrition decisions. The instructions are clear. However, it's somewhat annoying to read on the computer screen.

This won't make you skinny...


If you're looking for rapid weight loss, this isn't the diet for you. This will make your gut healthier and increase your body tone. You will only notice the results after several weeks, if not months. Just keep following the instructions! It's a slow process, but worth it.

Before and After


I was looking forward to purchasing this e-book ever since I heard what it was about. I don't like commercial diets because I feel like I am eating unnatural foods, so the Lean Gut Diet appealed to me because it didn't sell any artificial products.

Dr. Larson didn't disappoint. 2 months after starting the plan, I've lost 30lbs and 6 inches around my waist. I finally feel healthy, and I can't wait to see my body continue to change in the future!

Bacteria balance


The tips in the e-book are useful, and I must admit that I have lost some weight since I started following the instructions. However, as soon as I opened that PDF file I realized it was too much information for me. It was difficult to dig through what I wanted to know and what I didn't care to read about. Although the guide is helpful and I saw results, I only give 3 stars because I felt like not all information was necessary.

I lost 25lbs in 1 month!


As the title suggests, I made a dramatic transformation of my body in only the first month of following Samuel Larson's guide. He is brilliant, and I am so happy I found this diet plan when I did. I can't urge you enough to try this for yourself!



I started following all of the instructions from the Lean Gut Diet almost 3 weeks ago. I haven't noticed any weight loss. I'm glad there is a 60-day satisfaction guarantee, as unfortunately, I have to ask for a refund!

NOT a scam!


I got the Lean Gut Diet e-book so that I could improve my digestion and get healthier. I wasn't really looking to lose weight, but I had some digestion problems and symptoms that bothered me for many years.

The diet resolved all my problems within 2 weeks. I noticed an improvement after a few days, and it only got better from there.

My only concern was that the e-book was a little tiring to read from a screen. I solved that problem by printing the pages, and now I have a hard copy. It's worth it!

Wow! Amazing results


I am so happy I bought the Lean Gut Diet! The e-book helped me understand how my body and metabolism work. I wasn't just following instructions, but understanding why I was taking certain steps. Without a doubt, this has been the transformation of a lifetime! I lost 6 inches around my waste in the first month. Best of all, I didn't have to endure unbearable exercise or starve myself! I would recommend this to anyone.

Finally, a diet that worked!


I've been trying to lose weight for the past 10 years. I am not significantly overweight, but I had some belly fat that affected my self-esteem, and I wanted to get rid of it.

I got a gym membership and even joined a boot-camp. I've tried cutting back on calories but eventually I just quit each of my diet techniques. I can't say that the attempts were useless, but I didn't achieve the results I wanted.

When I read the guide for the Lean Gut Diet, it didn't seem revolutionary to me. Nonetheless, I noticed a change in my body after only a few days of following Dr. Larson's plan. Weeks later, I had finally shed the extra weight, and I've achieved the body I've always dreamed of.

Thank you so much, Dr. Larson!
