Male: 9250 ~10090 kj (2211~ 2412kcal), female:? 7980 ~ 8820 kJ (1907 ~ 2 108 kcal). Note: The daily calories provided by food should be no less than 5,000-7,500 kilojoules (1 195- 1793 kilocalories), which is the least energy to maintain normal life activities.

Simple algorithm of basic metabolism of human body;

Woman: basic calories = weight (kg) x 9

Man: basic calorie (kcal) = weight (kg) x 10.

Calculation formula of daily calorie requirement for adults

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.

2. The calories required for digesting food = 10% x (minimum calories required for basic metabolism+calories required for physical activity) = 1. 1 x (minimum calories required for basic metabolism+calories required for physical activity).
