Omni Diet Review - Does This Diet Work? Are a conflict of interest and questionable ingredients deal breakers?

Editor's Review: 3.5 / 5.0
Omni Diet Review

Losing weight based on diet and exercise is one of the most reliable methods, if the regimen is healthy and safe. However, it can be very difficult to find a diet plan that is effective and easy to use so we were looking forward to learning more about this diet plan. We examined the plan itself and read hundreds of reviews to put together all of the information you need to know.

EDITOR'S TIP: Combine Omni Diet with a proven fat burner such as Leptigen for better results.

What You Need to Know

The Omni Diet plan was created by Tana Amen, who is a nurse and fitness expert. It promotes a holistic approach to losing weight by encouraging dieters to eat a diet that is 30% protein and 70% plant based. She also requires foods to be all organic and has several other restrictions.

This is an all natural diet program, however, the restrictions are extreme. Dieters are not allowed to have any dairy, meats and eggs must be free range and hormone free, everything must be organic, soy products are prohibited, as are most oils, fruit juice, and processed foods. This seems a lot like other popular health plans but read on…

Conflict of Interest

One of the main concerns is that throughout the book, the author heavily promotes dietary supplements made by her husband’s company. This is extremely suspicious and for a diet plan to claim to be healthy and still require so much space dedicated to why supplements are needed seems more like a marketing ploy than a truly new way to eat.

According to our research editor, “Many of the changes recommended in the diet plan are useful in improving the health of people suffering from a variety of health issues, however, it is not revolutionary.”

Impossible Ingredients

After looking at numerous reviews and sample recipes, it appears that many of the staple ingredients are nearly impossible to find for many consumers. For those who are able to find them, they are frequently prohibitively expensive. One reviewer said, “Unless you live in a big city to have access to all items required, have unlimited time for preparation and a large food budget, this book is not for you. Well written, well researched but not for a dieter desperate for help.”

Our research indicates that if you will likely lose weight following the method outlined in the book. However, according to the author you will probably still need supplements. Considering the cost and difficulty of implementing the plan by itself, this is not welcome news.

The Science

The author is a medical professional who spent a decade looking for ways to improve her own health. She looked carefully at the relationship between the body and the food we fuel it with. Along the way she discovered good nutrition doesn’t just impact weight loss, but can also help decrease inflammation, reverse chronic disease, and improve the quality of life. The research is interesting, but possibly biased. Independent verification of the results and advice are not provided.

Leptigen is one of the best. The clinically proven ingredients are all well known for their weight loss properties. Our research indicates dieters are satisfied with the product and have had no negative side effects.

The manufacturers of Leptigen believe so strongly in their product, they have offered new customers a special trial offer, something we love to see.

Product Features

The Omni Diet is described as a 70% plant 30% protein diet. It is a dairy and hormone free plan that only includes organic, non-inflammatory foods. The diet’s first goal is to improve your health, and any weight loss you see is just a side effect. The primary goal is to reduce inflammation and improve nutrition. Organic, free-range eggs are allowed on the plan, but soy based products, vegetable oils high in omega 6s, refinded sugars and carbs, fruit juice, and highly processed foods are eliminated. Only high quality animal protein sources are allowed. There are more than 100 recipes to help people get started on the diet, which the author suggests sticking to for at least two weeks, as it can take this long to detox and reset the tastebuds. WIth this diet, you are asked to commit to five changes, of the total 16, during the first two weeks. Dietary supplementation is recommended on this program. Part of the book is dedicated to promoting her husband, Dr. Daniel Amen’s supplement line.

  • The Omni Diet is written by a fitness expert, who is also a nurse.
  • This offers a holistic approach to weight loss.


  • The Omni Diet can be out of budget for a lot of people because organic and free range foods are more expensive.
  • Some people will have a hard time letting go of sugar and dairy products.
  • There is a conflict of interest because she promotes her husband’s supplements.
  • Reading a book does not mean you’ll lose weight.


The Omni Diet is a less restrictive plant based diet, but is still highly restrictive for a lot of us. While we like that the focus is on health and nutrition, and not solely on weight loss, this approach is not practical for the majority of dieters. Whatever approach you choose, should focus on a nutritionally balanced, reduced calorie, diet, that is combined with regular exercise featuring both cardio and strength training. If you want to increase your results compared to diet and exercise alone, add a clinically proven safe and effective weight loss supplement.
