Thrive Diet Review - Does This Diet Plan Work? Are food restriction and lack of clinical support deal breakers?

Editor's Review: 3.5 / 5.0

thrive-diet-product-imageDieters seem excited to try the Thrive Diet – the perfect reason for us to lift the veil on this nutrition program. We checked on approved food lists, customer reactions, relevant author education and clinical support. With all our findings we present the customer with just the facts.

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

What You Need to Know

Thrive Diet is a vegan nutrition guide that aims to change the way dieters eat over time. You start off by adding healthy foods, but eventually you take some “unhealthy” ones, as listed in the book, away. The majority of the recipes are prepared at home, but you can package meals to consume on the go.

The Thrive Diet program comes with multiple recipe books and nutrition guides, but the main plan was printed in 2007. All-natural foods without preservatives are encouraged – a good option. We like the affordability and positive comments from athletes, but read on…

Food Restriction – “Too Much?”

Part of the Thrive Diet is the recalibration period. During this time you eliminate all caffeine, grains, meat and even some starchy vegetables. There is a complete list of approved foods, but only in the book. The author, Brendan Brazier, suggests sesame seeds, acai juice, coconut oil, quinoa and adzuki beans. “The foods suggested on the Thrive Diet may not be found in most pantries,” says our Research Editor. “If the dieter must restrict to this extent, the diet could be difficult to follow.”

“The recipes call for foreign, hard to find and not very palatable ingredients like popped amaranth, quinoa and hemp powder,” one reader explains.

Another dieter says, “This book is very informative but there are too many ingredients that I don’t have on hand.”

Education – “Maybe Not”

When presenting the dieter with a plan to improve health or lose weight, it’s good for the author to have some education in the field. Brendan Brazier is a former triathlete, but he has no formal training in nutrition. Some readers are concerned about where the suggestions come from. “Please be aware that Brendan Brazier is not qualified to dispense scientific information on nutrition. On Twitter he admits, ‘I wrote about what works well for me. That’s it’,” a reader expresses.

“Next time I will just make sure the author is a scientist that publishes in peer-reviewed journals,” offers another consumer.

Our research at DietSpotlight has shown issues like food restriction tend to negatively affect long-term success. If Thrive Diet does deeply narrow choices, that could be a problem for some dieters.

The Science

Nutrition programs like Thrive Diet are all about the science and Brendan Brazier does include clinical studies in the reference section. Printed information is difficult to verify online. We were unable to find any scientific support for the idea that vegan or raw diets were healthier than alternatives. When research does not support claims, we find issue with the product.

The Bottom Line

We were intrigued by the Thrive Diet. Athletes seem to like the plan, there are plenty of recipes and the book is affordable, but we don’t feel comfortable recommending it. The food restriction may be too tough for some dieters and the author is not educated in nutrition. Plus, we are concerned about the lack of clinical support.

If the time to lose more weight is now, our suggestion is to go for a supplement delivering a cost-effective solution formulated with scientifically researched ingredients.

Of the products we’ve researched in 2015, Leptigen is one of the best. The proprietary blend of ingredients have been shown to accelerate metabolism and boost fat loss. No customer reviews or forum posts mention side effects and dieters report good weight-loss results.

It is with confidence that the makers of Leptigen offer a Special Trial Offer – a good gesture.

Product Features

The Thrive Diet does not allow for any meat, dairy, or processed foods, which makes it highly restrictive and hard for many people to stick to for long periods of time. The diet is based on vegetarian meals, high in nutrients, so you can eat a little bit and feel full for a long period of time. Since the meals are nutrient dense and not calorie dense, you can eat what appears to be more food, without feeling the additional pounds. The book features more than 100 recipes to help you get started. There is also a 12 week meal plan so you have everything you know you are going to eat over a three month period. There are grocery lists so you can make sure you get everything you need when you take your trips to the grocery store. As a bonus, you get a list of staple items you should always keep in your kitchen pantry to ensure you can make a Thrive Diet friendly meal

  • The Thrive Diet is highly nutritious.
  • This diet is very Earth conscious.


  • The Thrive Diet is highly restrictive, featuring a long list of foods that are not allowed on this diet.
  • The restricted meal plan may be hard for people to follow for an extended period of time.
  • A lot of the recipes require you to devote an excessive amount of time to meal preparation.


The Thrive Diet is an excellent and healthy way to approach your diet and nutrition, if you can handle the highly restrictive nature of the diet. If you have the time to devote to meal preparation, then by all means, give this diet a try. If you do not do well with restrictions or are pressed for time, then you will need to find another diet program that will help you lose weight. You should also be doing an exercise program, and consider taking a clinically proven safe and effective weight loss supplement to accelerate your weight loss efforts.

    I want to know the ingredents in all the Thrive products. My friend gave me a 3 day trial and I want to make sure it’s not going to interact with some of my medications. I look forward to hearing from you.
    Thank you.

    Always read the ingredients. These are new companies and usually fly by night fads and can be harmful long term.
    Find an established company to buy from and preferably no diet drugs. Fast Fixes Never Last.

    I believe the Thrive diet your talking about is not the same as this Thrive. These are vitamins.
    Please let me know if I am wrong. I just started a week ago.

    The best way to combat fibromyalgia is to take a candida killer and lots of probiotics. Inflammation causes pain, eliminate inflammation and eliminate pain.

    I have a kidney disease and I cant eat or drink anything that’s high in protein. could thrive do damage to my kidneys?



    Hi there Lesa, a friend of mine introduced me to the products. I was very interested at 1st. I am a nursing momma so i did my own research on the ingredients. I found very scary long term side effects with Silica. Says over time can build up and cause kidney problems, kidney stones ect… Thank you for being careful and not going head first into something like this. I was told it was safe for pregnant/ nursing moms however many of the ingredients are very contraindicated for mommas.

    I have not started the diet because I am a heart patient and wonder about all of the caffeine. Is this safe?

    Most people do not know that thrive has some chemicals in it that have harmful long term affects. I heard from aFriend who is a nutrition specialist that this thrive product will be pulled off the shelves before long.
    On the other hand
    I am an ambassador with Plexus world wide
    our products are all natural plant based products. And our signature product plexus slim is actually OK to take while pregnant and does wonders for people with fibromyalgia… migraines
    an multitude of health benefits. Im a silver ambassador with plexus world wide. I felt compelled to inform that if you also take these products it can cause you to fail a drug test also. Just an FYI.
    Anyone wanting information on plexus products and how you can make a step to a healthier lifestyle
    Plexus is not a diet nor a meal replacement. It is strictly a tool we have found that helps with high blood pressure
    Cholesterol etc.
    Contact me for more information.



    I have to say that you will not fail a drug test while taking the Thrive. My husband has been in thrive powder drink, pill and the thrive patch for about 3 months now and he is a truck driver and just took a drug test and passed it, on the other hand, I personally don’t think the stuff works and is a waist of money. He has lost about 35 pounds but, he has also changed what he eats everyday. Which he could have done without the Thrive,right? He is still in a lot of pain from old injuries that he has gotten over the years and he still has no energy. He just stated getting nauseated over the lat couple of days, which he seems to think it may be the patches, I don’t know.

    I do not take any of these products. I was researching Thrive because my daughter inlaw is selling it. I researched Plexus, Ace and Thrive. I have Family and friends on all 3. Phil is on Plexus and lost weight and loves it. Betty Smith on Google rips it apart with logic. My Friend Kristen has been Ace for 2 years and is now lean and a Rep. She is a size 3 from a size 12. She loves it. My daughter inlaw loves Thrive and is a Rep now. She loves the energy. Be careful and read. Amazon removed Plexus from their site because of health concerns. So on to researching Ace and Thrive now



    What is Ace?
