The total calorie intake of a normal person should be 2000 calories a day, and people who exercise can increase it appropriately.

There is no uniform standard for calorie intake, which should be calculated according to everyone's weight and activity. The heat required by human body varies from person to person, and the main factors affecting heat are labor intensity, age, climate change, body shape, weight and health status.

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.

If the goal is to lose weight, multiply your current weight (kg) by 10,1or 12( 10 means your metabolism is slow, 1 1 means medium./kloc

Extended data

Calorie (Cal for short), transliterated from English Calorie, is defined as the heat required to raise 1 gram of water to 1 degree Celsius at 1 atmospheric pressure; Calorie is an energy unit, which is still widely used in nutrition measurement and fitness manual. The international standard unit of energy is joule.

Controlling energy intake and proper exercise are very effective ways to lose weight, and most doctors think it is the healthiest way to lose weight. This mechanism is very simple. When the daily energy intake is not enough to provide the energy consumed by the body, the body will call the sugar and fat stored in it. When fat is broken down and provides energy for the body, the process of losing weight begins.

However, it should be noted that excessive dieting will do harm to the stomach and digestive system. Some doctors pointed out that the control of energy intake should be gradual, so as to ensure that the human body can adapt slowly, and the energy intake per day is generally not less than 800 calories, otherwise the human body will make up for the lack of energy intake by reducing its physical function.
