The calculation formula of daily calorie requirement is weight × 25-30kal/kg/d. If the daily activity is low, for example, white-collar workers who work in offices can choose 25, and if the activity is high, they can choose 30. There are three concepts of weight: actual weight, ideal weight and corrected weight. The actual weight is the actual weight, and the ideal weight is the value obtained from the height of-105.

If the actual weight is lower than the ideal weight, the actual weight is × 25-30kal/kg/d; if the actual weight is greater than the ideal weight, it is necessary to further calculate the corrected weight, that is, the actual weight-ideal weight× 0.5+ideal weight is the corrected weight.
