Have you ever wondered how workers in the health field assess health risk factors from a person-to-person basis? One way health workers like doctors, personal trainers, and health coaches deduct how healthy a person may or may not be is by assessing if they are in a healthy weight range or not. The most common standard for assessing this is by calculating someone’s BMI or Body Mass Index.

This article today is an attempt to teach you, the reader, about the different types of health risk factors that are associated with each category!

Disclaimer: There is one limiting factor when it comes to assessing BMI. That limiting factor would be that it does not account for “fat free mass”. Fat free mass would be things like bone, organs, water, but most importantly in this case muscle.  Since muscle weighs more than fat some individuals, most commonly athletes, will proportionally carry a lot more muscle than they do fat which can make them weight more bumping them up into a higher weight category. BMI is the Ultimate standard for in assessing body weight for normal adults, not athletes who train nearly every day.
