A vegetarian diet excludes meat, fish, and poultry and mostly focuses on plant foods. There is some variation in vegetarian diets as well, however. Some people exclude dairy products but allow eggs, for example.

The Argument

A vegetarian diet promotes weight loss because of the large number of fruits, vegetables, and whole grains consumed by the people on the vegetarian diet. These foods are all high in fiber which is a factor associated with lower body weight. Plant-based foods also typically have fewer calories and more nutrients than animal-based foods, another component in weight loss.[1] In addition, vegetarianism has been linked to a reduced risk of chronic diseases, but these benefits depend on which foods you eat.[2] Another perk of a vegetarian diet is its facility. For one, it is relatively nonrestrictive in comparison to some other diets; one is not required to monitor calories or forego processed foods, for instance. Also, vegetarian cookbooks, restaurants, and stores are generally easy to come by (though this may depend on the vegetarian's place of residence as some cities and countries have more options than others). Lastly, converting recipes is usually quite simple and typically involves using a vegetable-based protein such as tofu instead of meat or vegetable broth in place of the chicken or beef alternative.

Counter arguments

Though a vegetarian diet is intended to help people lose weight and reduce the risk of disease, it can have the opposite effect and negate any weight loss earned. This is because, unlike some other diets, a vegetarian diet does not restrict the number of refined carbs or highly processed foods, so some vegetarians tend to consume more of these and not as many fruits and vegetables as they should. The lack of rigidity of a vegetarian diet can, therefore, make it difficult for some people to maximize the health benefits of this diet. Another potential problem with a vegetarian diet is that vegetarians are more at risk of nutritional deficiencies due to their lack of meat consumption; it can be difficult to get enough protein as well as essential vitamins, such as vitamin B12.
