fat to obese

At what point do fat people become obese. There must be a line, but where is it?

And yes, I realize how stupid this question is

hrmm, i feel that 300+ would qualify as obese, no one can be close to 300 and be ripped, shack and the few that are are oddities.

well height is a factor to obesity. and then there's the weight of muscles.

If your BMI is 30 or higher, you're obese.

WUT?

Metric: BMI = kilograms / meters2(squared)
US: BMI = lb * 703 / in2 (squared)

Less than 18.5 underweight
18.5–24.9 normal weight
25.0–29.9 is overweight
30.0–34.9 is class I obesity
35.0–39.9 class II obesity
Over 40.0 class III obesity

the line would be around the waist, i believe
