It is often said that “the law of conservation of energy”, the amount of caloric intake and consumption of energy is basically equal to the weight gain will not be. Here is a brief introduction to the approximate amount of energy we consume every day. Our daily caloric needs are divided into two parts, one is the calories needed for the body’s basic metabolism, and the other is the calories needed for physical activity. Adults need about 9250~10090 kilojoules per day for men and 7980~8820 kilojoules for women (Note: the daily calories provided by food should be no less than 5000 kilojoules~7500 kilojoules, which is the minimum energy to maintain normal life activities of the human body. 1 calorie=1 kilocalorie=4.184 kilojoules) I. Calories needed for basic metabolism of human body of calories: (calories) Women 18-30 years old: 14.6x body weight (kg) + 450 31-60 years old: 8.6x body weight (kg) + 830 60 years old and above: 10.4x body weight (kg) + 600 Men 18-30 years old: 15.2x body weight (kg) + 680 31-60 years old: 11.5x body weight (kg) + 830 60 years old and above: 13.4 x body weight (kg) + 490 With the above formula we roughly calculate the base calories we need to consume in a day. Here we will see how many calories we need to consume for exercise. Second, the calories needed for physical activity: (calories) It is convenient for us to roughly calculate, for example: slow walk (4 km in an hour) 255 calories walker (6 km in an hour) 345 calories brisk walk (8 km in an hour) 555 calories climbing stairs 480 calories jogging (9 km in an hour) 655 calories, etc… Interested friends can look for themselves. However, some friends may feel that people are not the same and consume different calories. Here is a finer algorithm (calories): Calories needed for activity = basic calories needed for basic human metabolism x activity intensity coefficient Activity intensity is divided into very light (such as reading, driving, etc.), light (such as walking, room cleaning, golf, etc.), medium (such as badminton, dancing, skiing, etc.), and heavy (such as heavy physical labor, basketball, soccer, etc.), and their activity intensity coefficients are about 0.2, 0.3, 0.4, 0.5. III. Daily calorie consumption: At the same time, as digestion also needs to consume calories. So the formula for our daily calorie consumption is (in calories): Adult daily calorie needs = 1.1 x (minimum basic calories needed for the body’s basal metabolism + calories needed for physical activity) Interested friends can calculate for themselves approximately how many calories we need to consume every day. Also, many food products have caloric values for that item on them. Note that their units are usually international units (kJ), and pay attention to the conversion units. Friends pay attention to health, beware of calories “eat” too much.
