So, just because some athletes have BMIs over 30, and they're not obese, we are to conclude that the BMI is worthless as a measure of anything?
I just did some noodling around on a BMI calculator that I found online. On my 5'6" frame, 186 pounds would give me a BMI of exactly 30. This is 54 pounds more than I currently weigh. Believe me, if I gained 54 pounds at my current fitness level, I would be obese, and I would be unhealthy.
Most of us aren't athletes (unless you really stretch the definition). So, here's a helpful hint: If your BMI is over 30, and you're not an "athlete", you probably weigh more than is healthy for you.
Is the BMI the one and only factor that should be used to assess one's health? Of course not. But, neither is it completely worthless.
