: 1, heat: The human body consumes energy all the time, which is provided by thermogenic nutrients in food. Nutrients that can produce calories 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 there is too much heat supply, the excess heat will be stored as fat. After a long time, the body will get fat.

2. Unit of calories: In nutrition, "kilocalories" is used as the unit of calories. 1 kcal is the heat required for1000g of water to rise from 15℃ to 1℃.

There are three main ways to consume heat. The first part is basal metabolic rate, which accounts for about 65-70% of the total calorie consumption of human body. The second part is physical activity, which accounts for about 15-30% of the total calorie consumption. The third part is the thermal effect of food, which accounts for at least about 10%. The proportion of these three parts has been basically fixed.

Calorific unit: calories, 1 calories = 1000 calories.

Nutrients that can provide calories in the diet are sugar (carbohydrate), fat, protein, alcohol, organic acids and so on. The calories they contain are: sugar (carbohydrate) 4 calories, fat 9 calories, protein 4 calories, alcohol 7 calories and organic acid 2.4 calories.
