What’s the Best Weight-Loss and Disease-Prevention Diet?
Why are vegetarian diets so effective in preventing and treating diabetes? Maybe it is because of the weight loss. As I discuss in my video The Best Diet for Weight Loss and Disease Prevention, those eating more plant-based tend to be significantly slimmer. That isn’t based on looking at a cross-section of the population either. You can perform an interventional trial and put it to the test in a randomized, controlled community-based trial of a whole food, plant-based diet.
“The key difference between this trial [of plant-based nutrition] and other approaches to weight loss was that participants were informed to eat the WFPB [whole food, plant-based] diet ad libitum and to focus efforts on diet, rather than increasing exercise.” Ad libitum means they could eat as much as they want; there was no calorie counting or portion control. They just ate. It was about improving the quality of the food rather than restricting the quantity of food. In the study, the researchers had participants focus just on a diet rather than exercising more exercise because they wanted to isolate the effects of eating more healthfully.
So, what happened? At the start of the study, the participants were, on average, obese at nearly 210 pounds (95 kg) with an average height of about 5’5” (165 cm). Three months into the trial, they were down about 18 pounds (8 kg)—without portion restrictions and eating all the healthy foods they wanted. At six months in, they were closer to 26 pounds (12 kg) lighter. You know how these weight-loss trials usually go, though. However, this wasn’t an institutional study where the participants were locked up and fed. In this trial, no meals were provided. The researchers just informed them about the benefits of plant-based eating and encouraged them to eat that way on their own, with their own families, and in their own homes, in their own communities. What you typically see in these “free-living” studies is weight loss at six months, with the weight creeping back or even getting worse by the end of a year. But, in this study, the participants were able to maintain that weight loss all year, as you can see below and at 1:57 in my video.
