BMI stands for Body Mass Index, which is the ratio of an individual’s weight (in kg) to the square of their height (in m). BMI categorizes weight and tracks potential weight gains and losses that may be directly related to health-related problems. The Body Mass Index ranges from near 18 to above 30, where less than 18 means underweight while beyond 30 signifies obesity. The usual BMI score that is free of any physical inaccuracies lies between 18.5 to 25. BMI is usually used by doctors and medical professionals to examine the body for any obesity risks. These troubles are underlying and might not surface till they become significantly prominent. For the same reason, the BMI comes in handy. This mathematical aid helps people and doctors to assess body fitness and trace any problems about your body weight.

Pros of Body Mass Index

No prior training

Even a 6th grader would be able to accurately find your Body Mass Index. This is because the calculation is simple, which uses a simple mathematical ratio. Even the conclusions are easy to chart. Look up your BMI score against the standard BMI sheet and, you can categorize yourself as underweight, normal, slightly overweight, or obese. Your accurate weight and height are all you need to know for your accurate BMI reading.

Prediction of cardiac attack

A high BMI represents obesity. This usually means that the fat accumulation of the body causes significant hindrance and disturbance. Cardiac arrests are common if the fat content of the body is high. Body Mass Index is an accurate index for rating the chances of a cardiac arrest. At various places, a high BMI can also help you secure profitable health insurance.

Global Statistics

Although the primary use of BMI is to conclude obesity, it is used in statistical analysis all across the world. Just like diabetes, AIDS, and other illnesses, obesity is a silent killer. It hampers the growth and activity of the body from within and may lead to even worst problems like strokes and high blood pressure. Scientists and researchers use the BMIs of several people from various places to conclude the obesity percentage of any geographical location. This is often used to track breakouts and the pertinent physical danger it poses to people all over. It helps to find out the die patterns that cause obesity in a large number of people.

Cons of Body Mass Index


Although BMI is a smart mathematical result, it is slightly inaccurate when certain parameters kick in. For instance, your muscle percentage alters your BMI. Older people do have more fat content in their bodies as compared to younger people. If your height and weight are proportionally more, your BMI would increase, this does not always mean that you are obese. Due to these small inconsistencies that affect the inaccuracy of the BMI, it is often not the primary concern of medical professionals.

The difference in fat levels 

BMI cannot trace the difference between the two types of fat and how they independently affect the body. Subcutaneous fat is under the skin, and it mostly affects your superficial body appearance. It is visceral fat that settles deep in your body, around your abdominal region, around the heart and poses a higher danger to your body. Over time, it is the accumulation of visceral fat that causes obesity.

Muscle and fat 

BMI reading does not consider the muscle content in your body. For instance, a muscular athlete would have a higher muscle content, but the BMI would consider at as extra fat. This does not mean the athlete is obese or beyond normal and healthy limits. Due to the same reason, a highly muscular athlete with an above-average height would end up falling under the obese category just like a short athlete who is slightly less muscular. 

BMI and your health

People have conflicting views on the advantages and disadvantages of BMI. However, it is still vital to measure your BMI regularly. It is not only a precaution to see if your body is unhealthy but also is a way to help you follow a healthy diet. If you are not in agreement with your BMI, you can look into your eating habits, reaffirm your exercise schedule and work towards making your Body Mass Index the way you want. It develops through habits and comes to stay from the ones you inculcate. The first step when you visit a dietician is to calculate your BMI. It is the standard way of going about your body weight to height ratio and is still widely used, at least for the initial diagnosis.
