How many calories should adults eat per day?

Men: 9250-10090 kilojoules; women: 7980-8820 kilojoules.

1. The daily caloric requirements of adults = the basic caloric requirements of the human body’s basal metabolism, the caloric requirements for physical activity, and the caloric requirements for digesting food.

(1) Calories required to digest food = 10 x (the minimum caloric required for human basal metabolism and caloric required for physical activity)

(2) Daily needs of adults Calories = 1.1 This is the minimum amount of energy required to maintain normal life activities of the human body

2. Simple algorithm of basic calories required for basal metabolism of the human body

Women: Basic calories (kcal) = weight (catties) x 9

Men: Basic calories (kcal) = weight (catties) x 10
