Body mass index (BMI) is a commonly used health assessment tool, which reflects whether a person's weight is healthy by calculating the relationship between his weight and height. A body mass index between 18.5 and 24.9 is considered as normal weight, while a body mass index below 18.5 can be considered as underweight, while a body mass index above 24.9 can be considered as overweight or obese. However, for athletes or people who do heavy physical labor, their body mass index may be higher, because they have more muscle content, and the weight of muscle is heavier than fat.
The calculation formula of body mass index is based on a large number of statistical data. It considers the comprehensive influence of height and weight to reflect whether a person's weight matches his height. If a person's body mass index is too high, he may face obesity-related problems, such as cardiovascular disease, diabetes and other health risks. On the contrary, if the body mass index is too low, then this person may have malnutrition or potential health problems.
Importance of body mass index;
1, health assessment: The body mass index can effectively assess whether a person's weight and height match, thus reflecting a person's physical health. Through the body mass index, we can judge whether a person is overweight, obese or underweight, so as to take corresponding health measures in time.
2. Disease prevention: The body mass index can be used as one of the risk factors for predicting some diseases. For example, obesity and overweight will increase the risk of cardiovascular disease, diabetes, hypertension and other diseases. By monitoring the body mass index, we can find and take measures to prevent these diseases in time.
3. Guide to lose weight: The body mass index can help people better understand their weight status, so as to make appropriate weight loss plans. For overweight or obese people, reducing the body mass index by controlling diet and increasing exercise is helpful to improve their health.
4. Instruct exercise: The body mass index can also provide guidance for exercise. A person's high body mass index may mean that he needs more exercise to stay healthy. In addition, for people who do heavy physical labor, their body mass index may be high, but this does not mean that they need to lose weight, but need more nutritional supplements and rest to stay healthy.
