Veelgestelde vragen
Is ideal weight just one number?
No, it's a range (BMI 18.5-24.9). "Ideal" varies by age, sex, muscle mass, bone density.
Which formula is most accurate?
Devine is popular. But consider frame size, muscle mass, sport training. BMI is rough starting point.
Can muscular people have "overweight" BMI?
Yes. Muscle is denser than fat. Body fat % is better than BMI for athletes.
