A review of 21 clinical trials has found that just one daily serving of legumes can facilitate an average drop of three-quarters of a pound over a six-week period. Published in the journal Obesity, the research analyzed results from studies that tested a total of 940 men and women eating about three-quarters of a cup of beans, lentils, chickpeas and other legumes each day. The subjects reported feeling nearly one-third fuller on average after eating about 5.6 ounces of these foods with their meals, compared with a control group’s diet. These beneficial legumes may also reduce body fat percentages.

According to senior study author and physician John Sievenpiper, Ph.D., of St. Michael’s Hospital’s Clinical Nutrition and Risk Factor Modification Center and the University of Toronto, “Ninety percent of weight-loss diets fail, resulting in weight regain, which may be due in part to hunger and food cravings. Knowing which foods make people feel fuller longer may help them lose weight and keep it off.”
