A vegetarian diet can be used as a weight loss tool. On average, vegetarians have a lower BMI than people who eat an omnivorous diet.[1][2][3][4] A vegetarian diet could help some people achieve a calorie deficit. This may be partly attributed to an increase in satiety as a result of an increased fiber intake.[5] Long-term studies on the effect of vegetarian diets on weight loss are still needed, and it is important to remember that any diet could produce weight loss if it creates a caloric deficit.[6][5][7][8]

A vegetarian diet can aid in weight loss because vegetarians typically have a lower BMI and may achieve a calorie deficit due to increased fiber intake, which enhances satiety. However, further long-term studies are necessary to fully understand its effects on weight loss.
