First, the basic metabolism of men and women in a day (doing nothing to maintain the normal operation of body life) requires the following calories:

1, male: 9250- 10090 kJ ≈2200 kcal -2400 kcal;

2. Female: 7980-8820 kJ ≈ 1900 kcal -2 100 kcal, which is the average (1 kcal =4. 182 kcal).

Second, if you are short or do light manual labor. Calorie intake is below average. For example, men consume 1, 800-2,000 calories a day, and women consume 1, 200- 1, 500 calories a day to avoid obesity.

Third, with the growth of age, for example, the elderly over 60 years old, men consume about 1500 calories a day, and women consume about 1000 calories a day. Of course, if you are tall, you can consume about 200 more calories.

Warm reminder: individuals have their own standards, which are not necessarily accurate. As long as you eat healthily and exercise more, you won't get fat.
