Is BMI of 45 dangerous?
BMI of 45 falls into the "Morbid Obesity/Class III" category. A BMI above 24.9 may indicate excess body weight. Consult a healthcare professional for personalized advice.
What weight gives a BMI of 45?
BMI is weight divided by height in metres squared, so it names a weight only once the height is fixed: at 170 cm (5 ft 7 in) a BMI of 45 means about 286.8 lb (130.1 kg). A taller person reaches the same BMI at a proportionally higher weight.
Does a BMI of 45 mean the same for men and women?
