    FAQ

    BMI of 42 — is it good or bad?

    BMI 42 for Males and Females means Morbid Obesity/Class III

    Is BMI of 42 dangerous?

    BMI of 42 falls into the "Morbid Obesity/Class III" category. A BMI of 25 or more may indicate excess body weight. Consult a healthcare professional for personalized advice.

    What weight gives a BMI of 42?

    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 42 means about 267.6 lb (121.4 kg). A taller person reaches the same BMI at a proportionally higher weight.

    Does a BMI of 42 mean the same for men and women?

    Yes — the WHO adult scale has no separate cut-offs by sex, so a BMI of 42 reads as "Morbid Obesity/Class III" for both. Age is what changes it: the adult table starts at 18, while children and teenagers aged 5–19 are compared with age- and sex-specific reference values instead.
