What BMI doesn't tell you about your health

BMI for Underweight -

Keep in mind that BMI is only a guide. It is not a tool to determine ideal body weight. It is a tool to help you see whether your weight is increasing your risk for disease. BMI does not work as well for people who are very muscular or those who have little muscle.

A muscular person may have a high BMI but still have a healthy level of body fat. A person with very little muscle may have a normal BMI but have unhealthy levels of body fat. A person who has a large change in BMI, even if he or she is not overweight or underweight, should be evaluated to find the cause.

Some people may be at risk with a lower BMI. Author: Healthwise Staff Medical Review: Anne C. Poinier MD - Internal Medicine Kathleen Romito MD - Family Medicine Martin J.

To calculate their WHR, a person should measure around their waist at the narrowest part, usually just above the belly button. They can then divide this measurement by the width of their hip at its widest part. Using WHR, a World Health Organization WHO report defines abdominal obesity as follows:.

However, as with BMI, the WHR does have limitations. Optimal WHR differs based on sex assigned at birth as well as race and ethnicity, according to the WHO report.

Plus, body size is not a direct measure of health. To discover more evidence-based information and resources for weight management, visit our dedicated hub. The waist-to-height ratio WtHR is another tool to assess body size. According to research , higher WtHR has associations with worse cholesterol and blood pressure, even at a healthy BMI.

If the result is 0. A study concluded that a WtHR of 0. However, this study did not account for ethnicity. For example, a 30 year old male with a 0. On average, a female of the same age and WHtR may be at risk of a 4.

Typically, obesity has associations with a high proportion of body fat. Obesity and overweight can carry a greater risk for conditions such as:. Calculating body fat percentage can provide useful information because it reflects body composition, unlike BMI, WHR, and WtHR.

Learn more about body fat levels by age and sex. The most common way of measuring body fat percentage is to use a skinfold measurement, which uses special calipers to pinch the skin. A health professional will measure tissue on the thigh, abdomen, and chest for males or upper arm for females.

While none of these can give a completely accurate reading, the estimates can be close enough to offer a reasonable assessment.
