# Understanding About Body Mass Index (BMI) And How do you calculate BMI?

Understanding About Body Mass Index (BMI) - Body Mass Index (BMI) is one way to find out your ideal body weight range and predict how much your health risk is. This method is used to determine a healthy weight based on weight and height.

Body Mass Index (BMI) is used to indicate a person's weight category whether it is proportional or not. Through BMI, someone will know whether their weight is in the normal category, excess, or just lacking.

Body mass index is obtained by dividing a person's weight in kilograms with their height in square meters. For some people, the body mass index value is likely to be inaccurate. Those who are pregnant, bodybuilders, or athletes with high activity levels are the group with BMI values that do not reflect health at that time. That is, even though their BMI values are above normal, it does not mean they have excessive fat.

#### How do you calculate BMI?

Classification of Body Weight Based on BMI

BMI calculations are divided into four categories:

• A person is obese if the BMI is equal to or above 30.
• When someone's BMI touches the numbers 25-29.9, then he is categorized as being overweight.
• Normal BMI is in the range of 18.5-24.9.
• If someone has a BMI below the number 18.5, then the person is underweight.

As for the Asian population, the BMI grouping is as follows:

• A person is obese if his BMI is above 25.
• When someone's BMI touches 23-24.9, he is categorized as overweight.
• Normal BMI is in the range of 18.5-22.9.
• If someone has a BMI below the number 18.5, then the person is underweight.

Unfortunately, the numbers above are less accurate when applied to people with eating disorders, such as anorexia nervosa. Body mass index numbers also do not represent those who are obese at extreme levels.

#### Don't Overly Rely on Body Mass Index

BMI can indeed be used as a benchmark so that someone is aware of abnormal weight. However, relying too much on that number is also not wise. One of the drawbacks of BMI calculation is that the results of BMI are general because they do not take into account other factors, such as the type of body shape, age, and level of one's activity.

• If there are two individuals having the same body mass index, but different s3x and age, then it needs to be taken into account.
• Where the weight of a person's body can also be a calculation of body mass index becomes inaccurate, for example, athletes or bodybuilders. Both groups are likely to have a higher weight because they have an athletic body. Body weight comes from muscle mass, not body fat.
• Based on age, for example, adults tend to have more body fat than children. While for s3x, women naturally have more body fat than men.
• Likewise with the activity and shape of a person's body. Despite having a normal body mass index, people who are less mobile may have more body fat. Those who have more fat in the stomach, are considered more susceptible to health problems.
• The fat that settles in the stomach and waist is associated with the risk of heart disease and type 2 diabetes. While those who have fat deposits on the hips and thighs are considered safer than the threat of these diseases.
• The thing that deserves attention but escapes the calculation of BMI is one's ethnicity. Each ethnic group is faced with its own health threat. For Asians, a BMI of 27 or higher includes obesity. In fact, the obesity category is generally in the range of BMI more than 30.
• Certain medical conditions or conditions, such as malnutrition or ascites, can also cause the calculation of BMI to be inaccurate. This is because of the increase in body weight due to the accumulation of body fluids.

#### The Importance of Maintaining Weight

Despite all the shortcomings, the calculation of BMI is well known primarily as a reminder to maintain weight. By having a normal weight, the following benefits can be obtained.

• Can do more activities because of higher stamina.
• Minimize a person from the risk of joint pain and muscle aches.
• Have a better sleep pattern and quality.
• Heart performance will be lighter.
• Blood circulation and metabolism will also be better.
• Reducing the risk of heart disease and certain cancers.
• Reduce cholesterol, triglycerides, blood glucose, and reduce the risk of type 2 diabetes.

Given the many advantages of having an ideal body weight, knowledge of body mass index is still feasible to maintain, especially as self-control. Make sure a healthy diet and regular exercise are your daily habits. If you are experiencing weight problems and have difficulty regulating or achieving your ideal body weight, you can consult a doctor to get further treatment steps.
