How Much Should I Weigh For My Height?

The correlation between the BMI and body fatness is fairly strong but even if 2 people have the same BMI, their level of body fatness may differ. In general,
  • At the same BMI, women tend to have more body fat than men.
  • At the same BMI, Blacks have less body fat than do Whites, and Asians have more body fat than do Whites
  • At the same BMI, older people, on average, tend to have more body fat than younger adults.
  • At the same BMI, athletes have less body fat than do non-athletes.
  • The accuracy of BMI as an indicator of body fatness also appears to be higher in persons with higher levels of BMI and body fatness. While, a person with a very high BMI (e.g. 35 kg/m2) is very likely to have high body fat, a relatively high BMI can be the results of either high body fat or high lean body mass (muscle and bone). A trained healthcare provider should perform appropriate health assessments in order to evaluate an individual's health status and risks.
  • People who are obese are at increased risk for many diseases and health conditions, including the following:
    • All-causes of death (mortality)
    • High blood pressure (Hypertension)
    • High LDL cholesterol, low HDL cholesterol, or high levels of triglycerides (Dyslipidemia)
    • Type 2 diabetes
    • Coronary heart disease
    • Stroke
    • Gallbladder disease
    • Osteoarthritis (a breakdown of cartilage and bone within a joint)

    • Chronic inflammation and increased oxidative stress
    • Some cancers (endometrial, breast, colon, kidney, gallbladder, and liver)
    • Low quality of life
    • Mental illness such as clinical depression, anxiety, and other mental disorders
