There is no unified standard for calorie intake, and it must be calculated based on each person's weight and activity level. The calories required by the human body vary from person to person, and the factors that affect it are mainly 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 1,800 to 1,900 calories a day, while men need 1,980 to 2,340 calories. Among them, protein intake should be 10% to 15% of the human body’s daily caloric requirements; carbohydrate intake should be no less than 55% of the human body’s daily caloric requirements; fat intake should not exceed the daily caloric requirements 30%. 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.

Calories needed to lose weight

Generally speaking, if you want to lose weight, you must keep the calories you consume every day greater than your intake. Heat is enough. The basic principle of weight loss is that the energy consumed is greater than the energy consumed. Therefore, by increasing exercise consumption on the basis of controlling diet, you can lose weight.

However, burning more calories than you take in does not mean you are thin. It does not mean that you can lose weight if you burn more than you take in. The most correct thing is that the calories consumed must be greater than the calories consumed, but the caloric intake must also be greater than the basal metabolism.

In fact, losing weight is not just about consuming energy or calories. Total calories must be controlled. If you want to lose weight, it is best to keep your total daily calories below 2,000. 1,600 is a relatively healthy calorie intake, and just do it with appropriate exercise.

However, during the period of weight loss, the daily calorie intake should not be too low. It is best not to be less than 800 calories, especially not lower than the basal metabolism. If things go on like this, it will be life-threatening. Besides, maintaining a balanced nutrition during weight loss is the correct and healthy way to start losing weight.
