Male: Basic calories (calories) = weight (kg) x 10.

Male: 9250- 10090 kilojoules? Female: 7980-8820 kilojoules

1, 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.

2. The heat required for digesting food = 10% x (the minimum heat required for basic metabolism of human body+the heat required for physical activity)

3. The daily calorie required by adults = 1. 1 x (the minimum basic calorie required by basic metabolism of human body+the calorie required by physical activity).

4. Note: The daily calories provided by food should be no less than 5,000-7,500 kilojoules, which is the minimum energy to maintain normal human life activities.

Extended data:

"15-degree calorie" for nutrition: the heat required to raise 1 gram of water from 1 4.5℃ to 15.5℃ at1atmospheric pressure is about 4./.

"4-degree calorie": the heat required to raise 1 g of water from 3.5℃ to 4.5℃ at 1 atmospheric pressure.

"20-degree calorie": The heat required to raise 1 g of water from 1 9.5℃ to 20.5℃ at1atmospheric pressure is about 4. 18 19 Joule.

"Average Calories": The average number of calories per degree required to raise 1 g of water from 0℃ to 1 00℃ at1atmospheric pressure is about 4. 190 Joules.
