Body mass index (BMI)


                                                                                                                      The body mass index (BMI) is your best starting point for health and body weight testing. This test is a very well-researched measurement tool and it only requires a scale. The average US adult needs to lose about 25 pounds. Find out how your body weight compares to your peers using the charts below.


Step on your scale, and then see your results on the mens and ladies charts below. When weighing in, be sure your scale is accurate. Remove your belt, shoes, phone, etc. Wear only undergarments if possible.

Find your height at the left side of the chart. Then find your weight within the chart on the same row as your height. Your BMI is at the top of the column where you find your weight.

If you are in the obese (red) or overweight (orange) category, your chart shows you how much weight you need to lose to be in the healthy weight category. 

*The 'Y' on the chart is for the average US male. Your weight loss requirements may vary depending the amount of muscle mass in your body. 


*The average lady is represented by the 'X' in the chart above. 


Waist circumference and waist hip ratio are equally important measurements. One reason you benefit from the other tests is that the BMI can't account as well for differences in muscle mass.

For example, if you have a very muscular build, you could get an 'overweight' rating even though you may be in good physical condition. Or, if you are thin but sedentary (you don't exercise), you could get a 'healthy weight' rating even though you don't have enough muscle in your body.

For a more complete profile of your body weight, take the waist circumference and waist-hip ratio tests also. Then find your results on the obesity scale, which will analyze your health risk using your body mass index and the results of the other 2 tests. 

Do you need to lose weight?  Regular exercise will burn extra calories and build lean muscle mass, which will improve your metabolism. Begin a new active lifestyle that includes a healthy diet, and you’ll make the changes your body needs for you to be well.
