1, the daily calories required by adults = the basic calories required for basic metabolism of human body+the calories required for physical activity+the calories required for digesting food.

(1) calories required to digest food = 10% x (minimum calories required for basic metabolism of human body+calories required for physical activity)

(2) Daily calorie requirement of adults = 1. 1 x (minimum basic calorie required for basic metabolism of human body+calorie required for physical activity).

Note: The daily calories provided by food should not be less than 5,000-7,500 kilojoules, which is the least energy to maintain normal life activities.

2, the role of heat

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.

Extended data:

Calorie (Cal for short), transliterated from English Calorie, is defined as the heat required to raise 1 gram of water to 1 degree Celsius at 1 atmospheric pressure; Calorie is an energy unit, which is still widely used in nutrition measurement and fitness manual. The international standard unit of energy is joule.

As the legal unit of food calories, joules are widely used in Europe, while calories are used in the United States. Although Joule is the legal unit in Chinese mainland and Taiwan Province Province, it is still widely used in Chinese mainland and Taiwan Province Province because of tradition.

Calories are units of energy. We often associate calories with food, but in fact they apply to any substance that contains energy.
