Think of each almond as a natural weight-loss pill. Combined with a calorie-restricted diet, consuming a little more than a quarter-cup of the nuts can decrease weight more effectively than a snack comprised of complex carbohydrates and safflower oil—after just two weeks! (And in this study of overweight and obese patients, after 24 weeks, those who ate the nuts experienced a 62 percent greater reduction in weight and BMI!) For optimal results, eat your daily serving before you hit the gym. Almonds, rich in the amino acid L-arginine, can actually help you burn more fat and carbs during workouts, a study printed in The Journal of the International Society of Sports Nutrition found.
