Need heat:
The daily calories needed by adults = the basic calories needed for basic metabolism of human body+the calories needed for physical activity+the calories needed for digesting food.
Calories required for digesting food = 10% x (minimum calories required for basic metabolism of human body+calories required for physical activity).
The daily calorie requirement of adults = 1. 1 x (the minimum basic calorie required by basic metabolism of human body+the calorie required by physical activity).
Heat action:
Just as computers consume electricity, trucks consume oil, and human daily activities also consume heat. In addition to providing people with energy needed for sports, daily work and life, heat also provides energy needed for human life activities, blood circulation, breathing, digestion and absorption, etc. People who lose weight can burn fat through exercise, and can achieve the effect of accelerating calorie consumption to achieve healthy weight loss.
Calories come from carbohydrates, fats and protein.
Carbohydrate generates heat energy =4 kcal/g.
Heat generated in protein =4 kcal/g.
Heat produced by fat = 9 kcal/g.
