This review is what happened after I obsessed over The Flexitarian Diet for weeks. We wrote one of our thorough reviews, closely examining the side effects, ingredients, customer service and clinical studies. Also, we focused on countless comments and experiences found on the web. Lastly, we took all of this information, condensed and summarized it to give you the bottom line.

What You Need To Know

First off, The Flexitarian Diet is a book written by Dawn Jackson Blatner (registered dietician). It provides 140 different recipes that are described as both quick and delicious. In order to follow this plan, you need to focus on eating mostly plant-based foods. You need to cut back on meat as much as possible, since they contain saturated fats. This in turn should help lower your BMI, improve overall health and assist with weight-loss.

The Flexitarian Diet was first published in September of 2008 and there is some positive customer feedback posted on websites such as Amazon. Furthermore, this text is available for the Kindle for only $9.99 and we appreciate that anyone can try this program, but read on…

Lack of Clinical Proof – “Nothing There?”

The first problem we had with The Flexitarian Diet is the lack of clinical evidence to support the claims regarding weight-loss. “The reality is a vegetarian-based menu can be healthy since meats and saturated fats are avoided, but this does not mean fewer calories are consumed. The amount you eat each day will certainly have an impact,” says our Research Editor.

One customer said, “This book forgets about servings and portion control, which are needed for weight-loss.”

“No actual weight-loss for me,” said one dieter.

Dietary Restrictions – “Another Problem”

After reading a number of reviews pertaining to The Flexitarian Diet, it’s clear that plenty of customers are not okay with the food restrictions. In fact, one person stated, “No meat, fish, animal byproducts (cheese, milk, eggs, etc.) at all? OMG, who are these people and how do they do this??”

Another said, “Her food choices are not up to my standards, though. She lists some pretty crappy food.”

We have concluded through our research that if there is some individual part of a weight-loss program that is especially burdensome (pills that make you jittery, too few meal options, lack of scientific evidence) the likelihood of success for the long term is not good. Unfortunately, if The Flexitarian Diet’s food restrictions bother a large number of people, this could prove to be troublesome.

Is There Clinically Proven Science?

According to Dawn Jackson Blatner, The Flexitarian Diet is a proven way to improve health, lose weight and even prevent cancer. Sadly, we couldn’t find any scientific research to support these claims. We at DietSpotlight need to see conclusive clinical evidence supporting a specific plan or weight-loss pill in order to stand behind the product.

The Bottom Line – Does The Flexitarian Diet Work?

Hey there, is it time to rush out for this one? We appreciate that The Flexitarian Diet encourages people to eat less meat and saturated fats and there have been some studies that have shown that vegetarians are less prone to heart disease and high cholesterol. However, we have reservations about recommending this plan because there is no published clinical evidence backing it for weight-loss. Also, some people have complained about the food restrictions and unsavory recipes.

For people who really want to drop pounds and get in shape, we advise you to pick a diet program or weight-loss supplement that’s easy on the wallet and is backed by real clinical studies. It’s helpful if there are no restrictions to worry about.

Among the best products we’ve seen in 2016 one is called Leptigen. This supplement contains a proprietary ingredient blend that has been proven in published scientific research to help encourage fat loss and increase metabolism. Also, we can’t find any complaints about adverse reactions and customer talk around the web expresses people are seeing serious results.

Also, the makers of Leptigen show confidence in their supplement by offering a Special Trial Offer, which is an amazing addition.

The Flexitarian Diet offers a natural way to move from eating a meat-based diet to a more vegetarian style. The idea is to replace some animal protein with vegetable protein. There are very few reports of side effects, but we did find a couple that came up time and again – boredom and offense to recipe simplicity.


“The book moved into a maddeningly perky infomercial. I was losing enthusiasm so i went to make a recipe.”   Tatjana


“I was a bit offended when the author decided that I needed a full page recipe for Peanut Butter Filled Celery!”    Judith

We studied the Flexitarian Diet ingredients so we could give you the information you really want.

Plant Protein

Plant protein is consumed primarily by those who are vegan or vegetarian. Some sources of this include beans, green vegetables, seeds, grains, fruits, and nuts.

What Is It Supposed To Do?

Consuming plant-based protein is a good way to include not only protein in your diet, but also vitamins, amino acids, minerals, and antioxidants.

Clinical Research

According to a study published in Preventive Nutrition and Food Science, “Although we did not clarify the active anti-obesity compound in CGH [corn gluten hydrolysate], we confirmed that only the CGH diet had a weight reducing effect by lowering adipose tissue weight and affecting the activities of hepatic lipogenic enzymes compared with the other protein diets among various plant protein sources and their hydrolysates.” Other plant proteins that were tested include wheat gluten and soybean protein isolate.

You could try supplementing the Flexitarian Diet with a weight-loss product like Leptigen. It contains clinically tested ingredients and is backed by amazing reviews.


Dairy is derived from any mammal that secretes milk. It is often consumed from cows and can make products like cheese, ice cream, smoothies, yogurt, and sherbet.

What Is It Supposed To Do?

Dairy is a good source of calcium. It also contains vitamin D and potassium. With the right amount of consumption, it can help an individual develop stronger bones, lower blood pressure, decrease cholesterol, and reduce the risk of cardiovascular disease.

Clinical Research

According to a study published in Obesity Research, “Increasing dietary calcium significantly augmented weight and fat loss secondary to caloric restriction and increased the percentage of fat lost from the trunk region, whereas dairy products exerted a substantially greater effect.” However, dairy intake on this diet is consumed on an individual base and they might not have these same results.

Whole Grains

A whole grain is composed of the entire kernel, including the bran, endosperm, and germ. Some common whole grains include oats, wheat, barley, rice, and quinoa.

What Is It Supposed To Do?

Consuming whole grains in the right way can be very beneficial for the body. Some benefits may include lower risks for asthma, cancer, gum disease, stroke, type-2 diabetes, and heart disease. It can also aid in weight-loss and stabilize blood pressure.

Clinical Research

According to the Journal of the American Dietetic Association, “… a hypocaloric diet with fiber-rich whole-grain cereal is effective for improving or maintaining other aspects of dietary quality during weight loss.” This simply addresses the nutritional contents of wheat and not the actual weight-loss it may cause.

Low-Calorie Diet

A low-calorie diet can simply be meal plan that provides fewer calories than one would normally consume. In regards to the Flexitarian Diet, the creators believe that the person will naturally follow a low calorie diet based upon the recommended foods in the book.

What Is It Supposed To Do?

A low-calorie diet can be beneficial for those who want to lose weight.

Clinical Research

In a study published in Obesity Research, researchers tested the reliability of low calorie diets and their association with significant weight-loss. In the conclusion, they wrote, “Low-calorie diets can be effective treatment, but the optimum way of delivering such diets remains unclear.”
