Fruits, vegetables, legumes, grains, and other plant-based foods improve weight loss and blood sugar in adults with overweight and type 2 diabetes, according to research presented at the European Congress on Obesity. A review of 11 studies showed following a vegan diet for 12 weeks improved heart disease risk factors such as body weight and blood sugar more than diets that included animal products. Vegan diets include more fiber and less saturated fat and fewer calories than omnivorous diets, which can help treat type 2 diabetes and overweight.
