Extended data:
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. Calories required for digesting food = 10% x (minimum calories required for basic metabolism of human body+calories required for physical activity).
3. Adults' daily calories = 1. 1 x (minimum basic calories required for basic metabolism of human body+calories required for physical activity).
4. The daily calories provided by food should be no less than 5,000-7,500 kilojoules, which is the least energy to maintain normal life activities.
Generally speaking, adults need at least 65,438+0,500 kilocalories of energy every day to maintain their body functions, because even if you lie still, your body still needs energy to maintain body temperature, cardiopulmonary function and brain operation. Basal metabolic consumption varies with individual height, weight, age and gender.
