Body Mass Index (BMI)

BMI Calculator
Current Height:
 Feet   Inches 
Current Weight:
 Pounds 

Your BMI is:

There are three measurements that can give you an assessment of your current overall health—your weight, your body mass index (BMI) and you waist circumference. Your BMI is also an important measure of your risk for diseases, including cardiovascular disease, diabetes, and a variety of cancers. Your BMI will go down as you lose weight, and the goal should be to get to a BMI of 25, or lower. Our Optimal Weight 5&1 Plan can help you do this safely and effectively. Just a 10 percent reduction in your weight can lower your risk of disease by over 50 percent! And that risk continues to decrease as you lower your BMI to the healthy number of 25 or lower.

One of the goals of each Coach is to help their overweight clients reach their optimal weight as measured by his or her Body Mass Index (BMI). The National Institutes of Health and the National Heart, Lung & Blood Institute support the use of BMI as it provides a more accurate measure of total body fat compared with the assessment of body weight alone.

Please note: There are some limitations to the Body Mass Index calculation, because it does not measure body composition. BMI overestimates body fat in persons who are very muscular and it can underestimate body fat in persons who have lost muscle mass—e.g., many elderly. People with more muscular builds may be classified as overweight according to BMI numbers even if they have a very healthy body fat percentage. A high BMI from increased muscle alone is not associated with health risks.
