BIM or Body Mass Index, in short, is a definite method to measure body size. In other words, it is an estimate of body size based on the height and weight of a person. However, body mass index can not be used for screening fat as well as accounting for ages, ethnicity, and muscles of adults directly. Thus, you have to use an equation for better results instead. In other words, body mass index can partly show your health whether you are overweight, underweight or medium.
In case you have got a high BMI, it means there is too much fat in your body than it expects. And, this sign tells you that you are unhealthy because you are around with some health risks like heart attack, diabetes, and high blood pressure.
In fact, the body mass index casually shows the relationship between the height and weight of children and adults. It also can be used for diagnosing the diabesity levels in the hospital nowadays. However, it also has its own limit, so it would be better if you should not believe in its result totally.
How is BMI Calculated?
BIM can be simply calculated by using the metric system or mathematical formula. If it is calculated with the metric system, the formula for BMI will take account into weight in kilograms divided by height in centimeters, then multiplying the result by 10,000,000 to get the last result.
Moreover, Body mass index is also calculated by using tables when it matches height in inches to weight in pounds. You are able to get some simple and convenient IBM calculators when you browse some websites on the internet also.
The formula is:
BMI = Weight (KG) ÷ Height (Metres²)
A person who is supposed to have a normal weight range if he has a BMI score which falls between 18.5 and 24.9. And, the BMI chart will be used to diagnose a person’s health if he is obese, overweight, normal or underweight.
What Does Your BMI Mean?
Now, the National Institutes of Health (NIH) defines the connection between the BIM and people’s health. You can recognize your body situation by looking at the traditional height/weight chart. BMI is a crucial index to let you know if you are underweight, normal, overweight or obese.
Your BMI is clarified into 6 levels:
- Less than 18.5: Underweight:
- 18.5 – 24.9: Normal Weight
- 25 – 29.9: Overweight
- 30 – 34.9: Obesity (Class 1)
- 35 – 39.9: Obesity (Class 2)
- 40+: Extreme Obesity (Class 3)
It is important to remain an ideal weight to have good health. According to WHO, you can easily to get risks if your BIM is less than 18.5 ( underweight ) or over 25 ( overweight ). And, it is really terrible if you are obese or overweight because you are around with several serious chronic diseases like diabetes, osteoarthritis along with endometrial, breast and colon cancer. Therefore, you have to be careful if you notice that your weight is increasing slightly.
Some Exceptions To The BMI Rule
The big question of BMI rule is “ Why does BMI become an exception for some group?”.
BIM does not show you much difference between muscle mass, body fat as well as children and adults. There are some exceptions to the BMI that you should know to get a better understanding.
People who are athletes or sporters will have more muscles than others because they need more energy for doing sweating activities. Thus, their BMI can be higher, but they are not overweight.
The disabled people are not capable to walk or carry things. They will have muscle wasting more than normal people. In fact, their BMI can be lower, but it is not a problem that affects their health. And, it does not mean that they are underweight.
Recently, children and teenagers are growing up really fast. Thus, it is tough to make a standard BMI for them. Casually, the BMI for people at the ages of 8 to 16 is between 18.5 and 24.5. If your children have a high BMI, you should give them a hand in order to control their weight better.
Obesity is usually diagnosed among shorter people instead of the taller ones. Therefore, BMI will be never good guidance for adults who are less than 150 cm or over 190 cm tall.
