Body Fat Index

Being obese is not just a function of your body weight, but also percentage of body fat. One may be normal weight or underweight, but still have excessive body fat. Inversely, someone who is over weight by a normal index, but has low body fat is not considered obese.

Use the following index to determine if you are normal or obese. Estimate your body fat with our body fat calculator if you have not had your body fat measured.
