Human body heat: in the process of human life activities, all life activities need energy, such as synthetic reaction of material metabolism, muscle contraction, gland secretion and so on. And these energies mainly come from food.
Nutrients contained in animal and plant foods can be divided into five categories: carbohydrates, lipids, protein, minerals and vitamins, and water is six categories. Among them, carbohydrate, fat (fat can also store calories) and protein can release energy through oxidation in the body. These three are collectively referred to as "productivity nutrients" or "heat sources".
