“4. Half of a group of 99 adults with type 2 diabetes ate a plant-based diet for 22 weeks. During this time, the other half followed the American Diabetes Association diet. The plant-based diet group lost more—almost 16 pounds in 12 weeks—despite the fact that the two groups rated their diets as equally acceptable and ate about the same number of calories. Those on the plant-based diet did not have to limit portion sizes artificially.   The consistent results keep rolling in from Europe.   1.
