According to the BMI, I am obese... The truth is, I am not obese. I am in better physical condition that most of my friends. Since moving to Boston, I don't use a car. I bike and walk everywhere I need to go sometimes with the help of the T. I also train in Judo ~3 times a week, which is one of the best full-body workouts I have ever participated in. I am in good shape and I eat healthy. My blood pressure is well within the normal range. I don't have six pack abs, but I don't have a beer gut either! I admit I am a big guy (6ft, 215lbs). I won't be starring in an xkcd comic strip anytime soon. However, I have a higher proportion of my body weight in muscle mass. People who have tried to guess my weight usually guess around 185-195lbs by the way I look. Can someone in the medical or bio community tell me why the BMI is used when it only accurately describes people who are of average build and do no physical activity whatsoever?
