Flexitarian Diet Ingredients and Side Effects
The Flexitarian Diet allows people to eat using the 3, 4, and 5 rule which means:
• Breakfast: 300 calories.
• Lunch: 400 calories.
• Dinner: 500 calories.
• Snacks: 2, 150 calorie snacks.
The book claims that no weighing or calorie counting is needed. This is not true however as when selecting whole foods the only way to determine the calorie content in by actually putting it on a scale.
Our review experts have crafted a list of the top ranked most effective weight loss diets.
By following this diet you’d be receiving a total of 1,500 calories a day. This is extremely low and may result in side effects such as:
• Stomach aches, extreme hunger, and a loss of vitamins and minerals.
• Nausea, headaches, and low blood sugar.
It does allow for some slight tweaks depending on activity level, gender and height, but this may still not amount to much more.
The advised calorie limit for men and women according to the NHS, a UK sponsored government group like the FDA is:
• Men: 2,500 calories a day to maintain.
• Women: 2,000 calories a day to maintain.
The reason why this diet emphasizes such a low amount of calories is due to the myth that one should subtract 500 calories of the often recommended 2,000 calories a day limit.
This has been debunked as 2,000 calories is a rough estimate and does not apply to all people. For example, men need on average an additional 500 more than the 2,000 calorie limit.
By subtracting calories at this high of a rate it’s likely one will not be satisfied enough to continue this this diet. For a list of the best weigh loss diets, follow the link here.
EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.
Flexitarian Diet Quality of Ingredients
The diet emphasizes eating a lot more whole foods such as grains, vegetables, and fruit. This is certainly a healthier way to diet, but it’s also very general and similar to basic advice already handed to dieters.
It also emphasizes a 1,500 calorie a day limit which may be too extreme for some. This number seems arbitrary, as caloric demands depend on a lot of factors.
They also emphasize not eating meat for 3 to 4 days as well. For people not used to a mostly vegetarian diet, it might not be satisfying enough or easy to sustain over time.

The Price and Quality of Flexitarian Diet
The book can be purchased for $11.91 currently on Amazon.com. The diet is healthy in one regard as it emphasizes eating a lot more vegetables. The main issue is that you’re only allowed such a limited amount of calories.
It’s already hard enough to avoid meat as much as this diet demands. To allow only such a few amounts of calories can be dangerous and unlikely to be sustainable over time.
30 minutes of moderate exercise are also advised 5 days a week. This can be substituted with 20 minutes of intense exercises just 3 days per week. Web MD has reviewed this diet and concluded:
“Becoming a vegetarian doesn’t guarantee weight loss”
They also criticize it for:
“it may not provide enough structure or guidance for people who need to lose weight quickly due to health condition”
“Doesn’t show you how to sensibly include higher-fat meat products”
A lot of time has to be dedicated to creating meals from all the advised whole foods. This can be hard for those who aren’t used to cooking so much, or who would be tempted to purchase cheap meals elsewhere.
Eating a mostly vegetarian diet is also known to help with weight loss since it’s harder to gain so many calories off whole foods alone. This is certainly healthier but the limitations imposed might be too extreme for some. Discover which weight loss diets were rated as the best overall by clicking this link.
Business of Flexitarian Diet
The creator is Dawn Jackson Blatner, a registered dietician and consultant for the Chicago Cubs. She wrote the official book in 2024.
Her website gives a brief description in which she states:
“Flexitarians weight 15% less, have a lower rate of heart diseases, diabetes and cancer, and live 3.6 years longer than their carnivorous counterparts”
This was based off of people who ate mostly a vegetarian based diet. While studies have shown eating more vegetables are healthier, the version outlined by the Flexitarian Diet is much different as it’s structured in a unique way.

Customer Opinions of Flexitarian Diet
Featured below are select quotes from customers:
“The diet can be summed up as eating more fruits, vegetables and whole grains, with a bit low lean meat. That’s it”
“basic vegetarian dishes with many spices but it’s not as healthy as it could be”
“I don’t see how you’d be able to keep up with this diet”
“the research is very vague and the recipes are incredibly bland and just not fixed the right way. Had to make a lot of changes”
Some enjoyed the book as it offered many recipes, but often people said it was not informative enough.
There were complaints about the overall quality of research, as they fail to cite specific studies and real science to verify the claims made.
Another issue customers had was that they found the diet incredibly basic. People said it had basic tips on weight loss such as eating fewer calories, getting more vegetables, and reducing overall meat. To see a list of the top ranked weight loss diet pills, click here.
Conclusion - Does Flexitarian Diet Work?
The Flexitarian Diet emphasizes eating foods which are certainly healthy. Eating more vegetables and whole foods can help promote weight loss, as it’s harder to gain so many calories from this kind of diet. The issue is that it emphasizes such a restrictive calorie limit. This may not be satisfying enough for people, especially those unaccustomed to a mostly vegetarian diet.

I have read your reviews, I disagree with you. I have been on dozens of weight loss food plans. I have lost weight on all of them, and gained every pound back and more ! Then turned around and spent more money on the next trending diet that also did not work. I realized if I could not eat that food every day for the rest of my ,t was not going to help me be what I wanted to be slim, healthy , and happy. Eating whole, clean, healthy foods was the only way to lose the weight for a life time. I give the Flexetarain five stars because it works !!!

+I think it's good for everyone to cut down (or totally eliminate) meat from their diets. There's enough proof that it's not good for your health. Also, and you transition try www.veggiebrothers.com if you want to have great tasting vegetarian food to enhance your flexitarian diet.

+This book is filled with delicious recipes (more than 100) that are very simple to make. Most recipes offer "flex swaps" so you can sub in/out meat when you feel the need. The "fact stacks" and nutrition tips are very helpful and the book is written in a very fun and approachable style. This book is more of a lifestyle than a diet and it has changed the way I eat! Great book!!!
