Need heat

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.

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

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

Male: 9250-10090kJ.
