LOL.
My BMI of 26(177cms, 82kg) - "You are fat, need dieting and exercise"
It can also return these results, depending on what information you give it:
"You're grossly undernourished, need hospitalization"
"You are grossly obese, consult your physician!"
"Umm... You are obese, want some liposuction?"
"You are starving. Go Find some food!"
"I envy you. Keep it up!!"
So, who else here is fat? obese? undernourished? enviable?

haha
