Obese can no more be treated as bad and lean body to be good. University of Pennsylvania physicians and obesity researchers gives a better way of assessing ones health prospects rather the common BMI (body mass index).

Before we learn more, let us find out what exactly refers to BMI. It is a simple calculation that finds result with the help of scale and a ruler. It simply helps in comparison of one individual to another and again to broad populations across years, cultures and continents. The calculation for BMI if reaches to a number of 30 or higher, this is considered as the line for obesity, which leads to cardiovascular disease, Type 2 diabetes and many more.

Well, several researchers have underscored the BMI. International Business Times writes, “For some with a BMI over 30, a welter of recent studies suggests obesity may confer some health benefits–a mystery widely referred to as the “obesity paradox.” Other new studies have shown that when some lean people develop diseases typically associated with obesity–such as Type 2 diabetes or cardiovascular disease–they’re more likely to die than if they had been fat with the same diseases.”

From data it is learned that 8 percent of normal-weight American adults are metabolically unhealthy. It also reveals 10 percent of the obese American adults are metabolically healthy. Also, it is not true that the BMI tells people who will live longer and prosper, and who will die early.

Apart from all these, researcher also said the excess weight could also be due to genetic, social, psychological and behavioral. So, the die early or live long, healthy or unhealthy are due to different reasons and not only for obesity.
