According to the book Calories and protein Intake published by the World Health Organization, a healthy adult woman needs to consume 1800 ~ 1900 calories every day, while men need 1980 ~ 2340 calories.
Among them, the intake of protein should be10% ~15% of the daily calories needed by human body; Should the intake of carbohydrates not be lower than the daily calories needed by the human body? 55%; The intake of fat should not exceed 30% of daily calories.
In addition, the daily intake of salt should not exceed 6 grams, and the daily intake of dietary fiber should not be less than 16 grams.
Extended data:
Daily calorie requirement of adults (1 calorie = 4. 184 kj)
Male: 9250- 10090 kJ?
Female: 7980-8820 kJ?
Note: The daily calories provided by food should not be less than 5,000-7,500 kilojoules, which is the least energy to maintain normal life activities.
In other words, you should be healthy and consume at least 1200 calories every day.
People consume at least three calories a day.
The basic heat required for basic metabolism of human body+the heat required for physical activity+the heat required for digesting food. ?
Simple algorithm of basal metabolism =?
Female: Basic calories (kilocalories) = weight (kilograms) x 9?
Man: Basic calories (kilocalories) = weight (kilograms) x 10?
Physical activity algorithm = weight (kg) * activity intensity coefficient * hours.
