## BMI for men

## BMI formula

The BMI (Body Mass Index) in (kg/m2) is equal to the mass in kilograms (kg) divided by the square height in meters (m):

BMI(kg/m^{2}) = mass(kg) / height^{2}(m)

The BMI (Body Mass Index) in (kg/m^{2}) is equal to the mass in pounds (lbs) divided by the square height in inches (in) times 703:

BMI(kg/m^{2}) = mass(lb) / height^{2}(in) × 703

## Categories

A common use of the BMI is to assess how far an individual's body weight departs from what is normal or desirable for a person's height. The weight excess or deficiency may, in part, be accounted for by body fat (adipose tissue) although other factors such as muscularity also affect BMI significantly (see discussion below and overweight).

The WHO regards a BMI of less than 18.5 as underweight and may indicate malnutrition, an eating disorder, or other health problems, while a BMI equal to or greater than 25 is considered overweight and above 30 is considered obese. These ranges of BMI values are valid only as statistical categories.

BMI Category | BMI Range (kg/m ^{2}) |
Health risk |
---|---|---|

Underweight | 18.4 and below | Malnutrition risk |

Normal weight | 18.5 - 24.9 | Low risk |

Overweight | 25 - 29.9 | Enchanced risk |

Moderately obese | 30 - 34.9 | Medium risk |

Severely obese | 35 - 39.9 | High risk |

Very severely obese | 40 and above | Very high risk |
