Body mass index (BMI) is an index recommended by WHO to evaluate health. It is an index in itself and is calculated by a fixed formula. WHO recommends this index from the perspective of disease. In order to distinguish between malnourished, normal and obese people, this data is common to both men and women, regardless of gender. ?
But there are some differences in bmi between men and women, because the bones of boys are generally larger than those of girls, so bmi should be slightly larger than that of girls. For example, the normal bmi of men is between 20 and 25, and that of women may be 18 to 23.
Maintain a healthy body mass index (BMI)
People of all ages should exercise every day, maintain energy balance and maintain a healthy body mass index. Generally, adults do moderate-intensity physical activity for at least five days a week (the cumulative activity time is 150 minutes), and do 6000 steps of active physical activity every day, which helps to maintain weight. If you don't want to walk 6000 steps, you can do these exercises instead.
The healthy weight of adults depends on the balance between energy intake and energy consumption. Proper energy intake and diversified foods help to maintain a healthy body mass index.
For obese people, the principle of diet adjustment is to balance the diet on the basis of controlling the total energy. Strictly control the intake of oil, properly control refined rice flour and meat, and ensure the adequate intake of vegetables, fruits and milk. The appropriate weight loss rate is 2-4kg/ month. It is suggested that overweight or obese people accumulate 60~90 minutes of moderate-intensity aerobic exercise every day, 5-7 days a week; Exercise resistance muscle strength every other day, each time 10~20 minutes.
