Many diets focus on a single food group and recommend cutting it out, so it will help people lose weight. The diet that will we will be focusing on today is the gluten free diet, which is the main treatment of Celiac disease and recently part of a new fad diet trend.
The gluten-free diet is based off the exclusion of the protein gluten. Gluten is the protein that is found in grains such as wheat, barley, rye and triticale which is a hybrid between wheat and rye.1 Many people claim that going on a gluten free diet is a great way to lose weight. In general, it may help you lose weight because you could be eliminating calories from your diet since many carbohydrate sources contain gluten. People could be eliminating a higher calorie food that contains gluten and replacing it with a lower calorie food such as a fruit or vegetable so overall, they are creating a caloric deficit.
It seems that most individuals who follow a gluten free diet do not have a physiologic requirement for the diet, such as a gluten or wheat allergy, and likely do not derive substantial benefit. There is existing evidence for potential harms of a gluten free diet which include possible nutritional deficiencies, financial costs, and negative psychosocial implications.2
