Understanding About Body Mass Index

The body mass Index (BMI) is one way to know your ideal weight range and predict how much risk your health disorder is. This method is used to determine a healthy weight based on weight and height.

The body mass index number or in English Body Mass Index (BMI) is used to indicate a person’s weight category whether proportional or not. Through the IMT, one would know whether the weight belongs to normal or ideal categories, excess, or lack.

Body mass index is obtained by dividing a person’s weight in kilograms in units with their height in quadratic meters. For some people, the body mass index value is likely inaccurate. Those who are pregnant, bodybuilders, or athletes with a high level of activity are groups with BMI values that do not reflect the health of the moment. That is, although their BMI value is above normal, it does not mean that they have excessive fat.

Weight classification based on IMT

BMI calculation is divided into four categories:

  • A person is obese if his BMI is equal to or above 30.
  • When a person’s IMT touches the 25-29,9 number, he is categorized as having overweight.
  • Normal BMI or weight is ideal in the range of 18.5-24,9.
  • If someone has a BMI below the number 18.5, then the person has a normal weight.

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

  • A person is obese if his BMI is above 25.
  • When a person’s IMT touches the 23-24,9 number, he is categorized as overweight.
  • Normal BMI ranges from 18.5-22,9.
  • If someone has a BMI below the number 18.5, then the person has a normal weight.

The bigger a person’s IMT, the bigger the body shape. Conversely, the lower the BMI, the person tends to have a lean body.

Unfortunately, the above figures are less accurate if applied to a feeding disorder sufferer, such as anorexia nervosa. The body mass index figures also do not represent those who are experiencing extreme levels of obesity.

Don’t rely too much on body mass index

BMI can be used as a benchmark for someone to be wary of abnormal weight. However, excessive reliance on those numbers is also unwise. One of the disadvantages of BMI calculation is the results of BMI is common because it does not take into account other factors, such as body type, age, and level of person’s activity.

  • If there are two individuals having the same body mass index, but different genders and ages, it is also necessary to count.
  • Where a person’s weight can also be the calculation of body mass index becomes inaccurate, such as athletes or bodybuilders. These two groups are likely to have a higher weight because it has an athletic body. Weight is derived from muscle mass, not body fat.
  • Based on age, for example, adults tend to have more body fat than children. While against gender, the people naturally have more body fat than men.
  • Likewise, the activity and shape of one’s body. Despite having a normal body mass index, people who are less likely to have more body fat. Those who have more fat in the stomach, are judged to be more susceptible to health disorders.
  • Fats that settle in the abdomen and waist are associated with the risk of heart disease and type 2 diabetes. While those with fat deposits in the hips and thighs are considered safer than the threat of these diseases.
  • It is worth noting that the BMI calculation is an ethnic person. Each ethnic is faced with its own health threat. For Asians, IMT 27 or higher is already including obesity. In fact, the category of obesity is generally in the BMI range of more than 30.
  • Certain diseases or medical conditions, such as malnutrition or ascites, may also cause the calculation of BMI to become inaccurate. This is due to the addition of weight loss due to body fluid heap.

The importance of maintaining weight

Despite all its shortcomings, BMI calculations are well known primarily as a reminder to maintain weight. If you have less weight, you can use vitamin supplements and improve your diet. Conversely, if your body is overweight, you can try a healthy diet and exercise more often.

By having a normal weight, the following benefits can be obtained.

  • Can do more activity due to higher stamina.
  • Minimize one’s risk of joint pain and muscle pain.
  • It has better pattern and sleep quality.
  • Heart performance will be lighter.
  • Blood circulation and metabolism will also be better.
  • Reduce the risk of certain cardiovascular diseases and cancers.
  • Reduce cholesterol, triglycerides, blood glucose, and lower risk of type 2 diabetes.

Given the many advantages of having an ideal body weight, the knowledge of body mass index is still feasible to be maintained primarily as a self-control. Make sure your healthy diet and regular exercise become your daily habits. If you are experiencing weight loss problems and are difficult to regulate or achieve the ideal weight, you can consult a doctor for further handling steps.
