Nuts and Your Weight
While it may seem odd, diets that include moderate amounts of nuts—which are inherently high in fat and calories—help prevent obesity and even reduce weight. One study found that dieters on a calorie-controlled, "moderate-fat" (35 percent of calories) plan that included nuts and other good fats lost as much weight as dieters on a 20-percent-fat calorie-controlled plan. The moderate-fat group also maintained their weight loss better than the low-fat group over the 18-month test period and beyond—likely because the "moderate-fat, nuts-allowed" group reported fewer problems with sensations of hunger than the low-fat diet group did.
