Extended data:

Heat means that when the change of system state comes from the destruction of thermal balance conditions, that is, from the temperature difference between the system and the outside world, we say that there is thermal interaction between the system and the outside world. As a result, energy is transferred from a high-temperature object to a low-temperature object, and the transferred energy is called heat. Heat and work are two different forms of energy transfer with the change of system state, and they are the measures of different forms of energy transfer. They are all related to the intermediate process of state change, so they are not functions of system state.

Calorific unit: In nutrition, kilocalories are used as the unit of calories. 1 kcal is the heat required for 1L 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.

To calculate the calories contained in food or diet, we must first know the weight of calorie nutrients, and then use the following formula to calculate:

Calories (kilocalories) = grams of sugar ×4+ grams of protein ×4+ grams of fat ×9+ grams of alcohol × 7.

The heat consumed by adults is utilized in three aspects: basic metabolism, activity and food thermal effect; During growth and pregnancy, the tissue structure needs extra heat.
