In order to keep healthy, it is enough to lose weight to the normal body mass index range. Body mass index, also known as body mass index, is a number obtained by dividing the weight in kilograms by the square of the height in meters. The normal value of adult body mass index is between 18.5-23.9. If the body mass index is lower than 18.5, considering underweight, the body mass index of 24-27 is overweight, and the body mass index of 28-32 is obesity. If the body mass index exceeds 32, it is a very obese situation. Body mass index (BMI) is the most commonly used index to measure obesity and health status in the world, but it should be noted that BMI is usually only applicable to adults, not to children and adolescents under 18. In addition, athletes, pregnant and lactating women, long-term bedridden and frail elderly people are not suitable for body mass index to judge.

There is another simple method, that is, your height minus 1 10 equals the kilograms of your normal weight, and a slight error in this range can make a rough judgment.
