I would like to know if there is a way to fight or opt out of the bmi of my child. I monotor, and watch wat my child eats. He will be a senior in school. I don't know where he will fall but he is not fat. he is in good shape. He is lean but not skinny. but the bmi is not a good source. They did a news report that according to bmi that will smith would be considered fat, michael jorden at his playing years for the bulls would be fat, arnold schwarzenegger would be even considered fat. The bmi is not accurate. My son is smart and can at time be tenderhearted and is sensative on his weight because he don't lift weights and are not buff like the football players (he's in the band), if they say he's fat because of bmi numbers that say will smith is fat, that is the last thing he needs. High school is hard enough. i was teased for being fat. I don't need teachers coming up and saying "your fat" too. Side note, I did loose weight but am constantly watching and obsessing about if I gain a single pound and I know it is because of being teased in school. O.K. pshyce eval over.
