Need heat:
Daily calorie requirement of adults = basic calorie required for basic metabolism of human body+calorie required for physical activity+calorie required for digestion of food.
Heat required for digesting food = 10% x (minimum heat required for basic metabolism of human body+heat required for physical activity).
Daily caloric requirement of adults = 1. 1 x (minimum basal caloric requirement for basic metabolism of human body+caloric requirement for physical activity).
Heating action:
Just as computers consume electricity and trucks consume oil, so do human daily activities. Heat not only provides energy for people's exercise, daily work and life, but also provides energy for human life activities, blood circulation, breathing, digestion and absorption. People who lose weight can burn fat through exercise, which can accelerate calorie consumption and achieve the goal of 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.
