Studies have shown that an apple a day can inhibit weight gain. People who eat an apple as a snack before eating spaghetti for dinner consume fewer calories than people who eat other snacks. Apple has a high fiber content, 4 to 5g each, which makes people feel full. In addition, antioxidants contained in apples help prevent metabolic syndrome. Apples are the ideal low-calorie snacks. To make a pie, chop a medium-sized apple, sprinkle with 1/2 tablespoons of sweet pepper and 1/2 tablespoons of cinnamon, and heat it in the microwave oven for one and a half minutes.
