The human body consumes energy all the time, which is provided by thermogenic nutrients in food. Nutrients that can generate heat in food are protein, fat, sugar and carbohydrate. They are oxidized to generate heat for the body to maintain life, grow and develop and exercise. When the heat energy supply is too much, the excess heat will become fat and be stored. After a long time, the body will get fat.
