Lose weight by removing meat, dairy and processed foods from your diet.

Top Rated Diets of 2022
What is it?

The Thrive Diet is a weight loss diet that claims to help reduce stress by offering whole foods, which in turn promotes weight loss. Vegan and raw foods are only allowed and all information about it is offered in The Thrive Diet book.

It’s intended to be used for a total of 12 weeks. However, adopting a vegan lifestyle is advised when one finished the total 12 weeks. There’s no limit on the amount of foods you can eat as long as they are from the accepted foods list. In reviewing many different weight loss diets our experts concluded the best solution was the 18Shake Diet. It offers both a meal replacement and diet pill made with natural ingredients and no stimulants. The benefits include appetite suppression for hours, increased metabolism, fat burning, improved mood and much more. Discover more information about the 18Shake Diet in the link provided here.

The link provided here has a list of the top 10 ranked diet plans.

A sample menu of the types of foods one will eat includes:

         • Zucchini chips.

         • Smoothie.

         • Pesto salad with tomato basil dressing.

         • Wild rice yam pancakes with agave nectar and fruit.

EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.

The Thrive Diet Quality of Ingredients

The types of foods one has to eat are all vegan and either raw or only slightly heated. It is healthy to introduce large amounts of vegetables, but it’s unknown if this diet will be easy for everyone to use. For those that have never tried a vegan diet this can be extremely restrictive.  This is why it’s advised by the creator to slowly ease oneself into a vegan lifestyle. It’s recommended to introduce some raw bars and more vegetables but to not completely follow each piece of advice.

Studies into what a raw vegan diet does to the body have shown possible side effects. One study featured in the Annals of Nutrition & Metabolism found:

“Pure vegetarian diets might cause cobalamin deficiency due to lack of dietary intake”

Cobalamin is also known as vitamin b12, which can result in side effects such as:

         • Fatigue, restlessness and difficulty with memories.

         • Breathlessness, poor balance, and anemia.

         • Brain and nerve damage which can become irreversible.

Another study by the Department on Nutrition and Wellness at Andrews University found:

“eliminating all animal products from the diet increases the risk of certain nutritional deficiencies”

“special concern for the vegan includes vitamin b-12 and D, calcium, and long-chain n-3 (omega-3) fatty acids”

This is why it’s often required for vegans to supplement with extra vitamins and minerals. These kinds of nutrients are sometimes found in vegetables, but they’re often not enough or cannot be digested properly. Yet another study by the University of Giessen showed that vegans have a risk for:

“higher mortality from coronary heart disease”

The benefits of eating raw foods have also been criticized, as many foods are more nutritionally bioavailable when cooked. This means that the body can process foods better when they are heated, which makes it easier to receivevitamins and minerals. A list of the top 10 ranked diet plans is made available when you click the link here.

According to Live Science:

“Raw foods certainly aren’t safer than cooked food”

“cooking… helps with the absorption of carotenoids such as beta-carotene and other nutrients”

The principles of The Thrive Diet are flawed, and the book provides no research of its own to prove why it’s any more effective than other diets. This makes it a poor quality diet, as the claims made are not backed up by any reliable evidence.  The registered dietician Janet Brill has commented on this diet by saying:

“the secret to good health and longevity lies not in a detox raw-food fad diet”

According to their analysis, though the added fruits and vegetables arehealthy, there are better ways to reduce stress and weight. No evidence is provided that The Thrive Diet would be a better approach to a vegan diet. Though it does allow for people to eat as much has they would like, it still can lead to serious nutritional deficiencies which can harm the body.

The Price and Quality of The Thrive Diet

The price depends on what grocery stores one goes to. However, there are many recommended foods such as hemp and pumpkin seed oil which can be very expensive.

One also might have to supplement in order to make up for the loss of vitamin b-12, vitamin D, iron, calcium and other nutrients.  This can raise the price of having to spend money on fresh wholefoods even more.

A serious potential risk of this diet is that it can lead to nutritional deficiencies. For a comprehensive top 10 list of the best diet plans for weight loss follow the link cited.

Business of The Thrive Diet

The Thrive Diet was created by the former endurance athlete Brendan Brazier. He was most famous for creating the Vega brand which makes supplements and foods.  He first created Thrive in 2022.

He does not explain how he came up with this diet, nor does he have a background in nutrition or weight loss diets. He does offer cookbooks that help provide more insight into what can be eaten while on this diet.

Customer Opinions of The Thrive Diet

Listed here are some direct quotes from users of the diet:

“contains many scientific explanations… unfortunately are not footnoted and therefore are unverifiable”

“recipes call for foreign, hard to find and not very palatable ingredients”

“making a large impact on my energy level”

“it’s an easy and fun read”

Any diet high in vegetables is likely to help produce increased energy and better mood. There were many who said they noticed an increase in energy.

There wasn’t much discussion on whether or not people lost weight or gained lean muscle mass as promised. There were only a handful of people that offered information about anything related to weight.

Some did mention that the food options are limited and that they were unable to find all the required foods. A common concern was that it became expensive, and that the food recommendations are unsatisfying. The link cited here has a comprehensive top 10 list of diet plans.

Conclusion - Does The Thrive DietWork?

The Thrive Diet is presented as a way to energize the body, support lean muscle growth, and aid in weight loss. It’s possible to lose weight when one only eats a vegan raw food based diet. The issue is that this might not be a healthy strategy. Many clinical studies have confirmed the fact that vegans require extra supplementation with vitamins and minerals. Raw foods have also been dismissed as being unnecessary, and there’s no proof provided that this is safe. Customers have also complained that there’s a lack of evidence for many of the claims. It’s also expensive according to users. Having to spend money on difficult to find or expensive food products which are specialty goods. The major criticism is thatthe author of this diet has not proven it works or is safe for weight loss.

Our experts have analyzed many diet plans and they have concluded the most effective for weight loss is the 18Shake Diet. It combines both a appetite suppressing meal replacement shake and a fat burning stimulant free diet pill. Both are made with natural ingredients, and customers have said they are potent in promoting well-rounded weight loss results. Customertestimonials and reviews are featured on their official website from satisfied users.

The 18Shake Diet is also backed by a full 30 day money back return policy. This allows for people to make a return with no questions asked within the 30 days. More information about the 18Shake Diet can be found when you click this link.

I feel better than I ever have. It’s a bunch of BS that you don’t get enough nutrients from a vegan diet! More and more athletes are doing it because it improves health, energy levels and well-being. Also has the benefit of being easier on the planet.

There are literally hundreds of studies to back up what he says. 18 shake diet being a better choice is really all anyone needs to see in this article to know it's nonsense.

This review of the thrive diet is absolutely ridiculous. Your trying to discredit a vegan diet as a whole because of some fake studies that are funded by meat and dairy interests. Even this review looks funded by that fake, synthetic shake company just so they can draw more attention for their own profits; not the consumers well being. The thrive diet is one of the healthiest diets anyone can follow and extremely affordable if you actually used your brain and looked at all your options. Being vegan has saved me money as i don’t buy fast food and the protein sources are incredibly cheap. TO EVERYONE READING THIS, GOING VEGAN IS THE ABSOLUTE MOST POSITIVE CHANGE FOR THE PLANET, THE ANIMALS, AND YOUR OWN HEALTH.

To discredit a raw, whole foods plant based diet with the excuse "may cause serious nutritional deficiency" is a statement of gross misinformation. Plant based diets are LOADED with macro and micro nutrients that FAR surpass a meat/dairy diet. Lack of nutritional knowledge is driving our obesity and disease laden epidemic to astounding levels. I'd gladly take a simple vitamin B12 supplement on a plant based diet than ingest the harmful tradeoffs of saturated fats from animal tissue to fortify my body with B-12. For the editor to promote a "fat burning free diet pill" as superior to a raw, whole foods plant based diet just furthers the conclusion that nutritional ignorance abounds. Buyer beware of someone who promotes a supplement or diet pill. Wonder who is benefiting from the sale of those products? Some of the largest population based studies ever conducted have proven the benefits of a whole foods plant based diet similar to what Brazier is advocating. Magic pills, sugar, and packaged foods or raw whole foods? One choice will make you sick the other won't. Roll your dice wisely.

This is a quick (don't take longer than a few minutes to make a lot of these things) better for the world, little energy, nothing dies and you feel better. After one week just trying a few things I feel a great improvement in my stamina, running and recovery. Great.

One of the major advantages to this book is that the recipes are designed for one person. It's really easy to double or triple a single recipe if you are feeding more, but it's a chore -- and often impossible -- to reduce recipes. And 99.9% of all published recipes appear designed to feed the masses.

I think this is fantastic. His principals make sense and the food is different and very delicious.
I don't think it takes too much time, no more than a normal meal in fact , if not faster.
Start at a pace that is right for you and gently ease into it. It will change your life and your health.

This book is excellent. It's an easy and fun read. The education it provides makes the decision to eat healthier easier. My girlfriend and I have been doing it for about a year now, and it has certainly become a part of who we are now. We cheat on occasion, and that will happen. In the long run, it hasn't mattered. You'll never look at the supermarket the same. Haha!

I have been using the Thrive Diet recipes for a while now. Braizer recommends to start slow and build, so I have started with the smoothies, energy bars and pre/post workout recommendations - so far these things are fast, nutritious and making a large impact in my energy level.
