Marc Nelson always knew his body was a little different. He played on the soccer team as an eight year old kid, but noticed his body didn't seem to develop the same way. Going to the doctors, they would tell him nothing was wrong due to him being in the safe BMI range. Marc suffers from lacking muscle mass though, creating many challenges with his weight and health. With that, Marc knows there are others who may also be struggling with BMI inaccuracy, so he has set out to study and help overcome the obesity health crisis.
