I start looking chubby at a BMI of 20. I'm positive that at even a BMI of 23, I'd be legitimately overweight for my frame.  BMI is flawed because it doesn't take different body frames into account. I feel a 24.9 BMI is only healthy for those with a really large frame. So anybody complaining about BMI being flawed, unless they're swole af, are just looking for an excuse to be overweight.
