Across a large population, the BMI correlates well with degree of body fat. However, there are certain exceptions. Very muscular, heavy athletes, who are actually quite lean when their body fat is measured, may have high BMI values. And in older adults, BMI frequently underestimates a person’s amount of body fat.
If you have a BMI in the overweight or obese category, you have a significantly increased risk for cardiovascular disease, type 2 diabetes, the metabolic syndrome, and various cancers.
BMI is determined by dividing your weight in kilograms by your height squared in meters. The calculator to the right will help.
