Complete nonsense. Unless you're in top tier of low BF muscular guys, a BMI putting someone in the obese range makes the risk of weight related health problems from cancer to kidney issues far higher than those who aren't obese.
This is the same bullshit narrative pushed by the fat acceptance movement, pointing to the rare exceptions of "healthy fats" instead of the overwhelming majority.
It's a rough measurement, not applicable in every single case, but the stats related to health outcomes and BMI are so clear, so overwhelming, only someone in complete denial would say it's "useless".
