Apple is a low-fat and low-calorie fruit. However, it should be noted that apples are just a kind of food, and cannot determine the problems of fat on human development and weight. We can eat more low-fat substances and eat two or three apples a day. It is unrealistic to lose weight, because the amount of fat ingested by human body must be consumed by the collision, extrusion and burning of heat and fat cells with blood and skin, so as to achieve the purpose of losing weight. If you want to know more clearly, you can look up substances with low fat, low sugar, low calorie, high moisture and high protein to adapt to it.
