Let's be honest, a 99.999% of people with a BMI > 27.5 did not get that way from hitting the gym too much. Weight lifters love to call out BMI as being worthless, but they ignore the fact that any exercise for American adults is rare, much less the amount of exercise required to hit a BMI of >25 due to pure muscle mass.

The average adult male is in terrible shape.

FWIW, people who exercise regularly should combine waist to height ratio (WHtR) with BMI. If you're BMI is high, but your WHtR is <0.5, then you're good. Otherwise, you're at risks for heart disease and stroke, even if you "look" healthy.
