What is BMI?

BMI or the Body Mass Index is the conventionally used method of classifying the weight to height ratio of an adult human body. BMI is widely known as the index of the fatness of an individual. It is also used as a risk factor for the development or prevalence of several health issues. The BMI has been most useful in population-based studies determining public health policies

However, conventional the BMI scale may be, it is a rather poor indicator of one’s health, as the BMI scale does not take body fat to muscle ratio into account? So a strong healthy person with more muscles than fat might appear overweight or obese where in truth he/she is not obese. So BMI is not a reliable method on its own.

BMI is widely used to normally classify the body types in 5 different categories:
Underweight
Healthy weight
Overweight
Moderately Obese
Obese

WHO and BMI

However unreliable the BMI method may be, the World Health Organization still acknowledges some risk factors that can be determined by raised BMI.

Some of those non-communicable diseases are:
cardiovascular diseases (mainly heart disease and stroke), which were the leading cause of death in 2012; diabetes; musculoskeletal disorders (especially osteoarthritis – a highly disabling degenerative disease of the joints); some cancers (including endometrial, breast, ovarian, prostate, liver, gallbladder, kidney, and colon).

The risk for these non-communicable diseases increases, with increases in BMI.

Factors affecting the accuracy of BMI

One of the problems of using BMI as an index of obesity is; it doesn’t differentiate between body lean mass and body fat mass, it doesn’t take into consideration the human body types. For instance, a person may have a very high BMI and still have very low body fat.

Anatomically speaking obesity is the excessive buildup of body fat (a.k.a. triglycerols) and on that note using the BMI as an obesity index is highly questionable.

BMI has multiple limiting factors, some of which are: not considering the relative age, gender, or ethnicity of the person. It also doesn’t take the body fat location into consideration, which plays an important role in finding out if a person is of a healthy weight or obese. For example, women in general naturally have a higher body fat percentage when compared to men but the BMI of a man in most cases is greater than a woman. This relatively poor correlation between the body mass to fat ratio in males has been proven multiple times in scientific studies.

Problems caused due to poor accuracy of BMI

Inaccurate determination of a person being fat or underweight may lead to many social and personal problems. Especially in the case of women, there is a social standard for a woman to have a desirable body shape which has changed multiple times over the few centuries. To achieve this specific set of “desirable” body characteristics they go through serious mental and social pressure and may acquire eating disorders and other diseases.

 
BMI being an unreliable method often hampers the mass study of other diseases affected by the body fat to muscle ratio. Some studies show that people with higher BMI have a higher risk of diabetes, myocardial infarction, stroke, and such non-communicable disease. Even though these studies were conducted on a mass number of people while not taking the family history of a disease, ethnicity, food habit, or other factors such as smoking, alcohol consumption, etc. into consideration.

At the end of the day, studies concerning the accuracy of BMI are still undergoing none of the results so far are set in stone. But one thing is for sure, that is having an excessively high BMI increases the probability of multiple diseases, social problems and can be limiting to one’s way of life. So leading a healthy lifestyle is always the right choice.

Eat healthy, dietary foods in moderation

Walking is the best exercise
