A vegan diet is best for gastrointestinal hormones and satiety, according to a study published in Nutrients. These hormones help regulate blood sugar, fullness, and weight management. Researchers, including the Physicians Committee’s clinical research director Hana Kahleova, M.D., compared a calorie and macronutrient-matched vegan meal with a meal composed of meat and cheese on hormone levels and after-meal satisfaction among 60 men: 20 with obesity, 20 with type 2 diabetes, and 20 who were healthy. The vegan meal increased satiety across all groups and increased certain beneficial hormones, compared with the non-vegan meal. These results add to the evidence that vegan diets may help prevent type 2 diabetes.
