Health  Calculators

Recently referenced research from a study published in the journal The Lancet Diabetes and Endocrinology indicates that measurement of Body Mass Index (BMI) provides a reasonable estimate of body fat for most people but has limitations.

For example, BMI may:

• Underestimate body fat for older adults or people with low muscle mass
• Overestimate body fat for people who are very muscular and physically fit

BMI and Waist Circumference Calculator --  from the Mayo Clinic: "...it's useful to look at waist size (measured slightly above the hipbones in adults) in addition to BMI. Health risks go up with increasing waist size, regardless of BMI...."

Body Mass Index -- BMI calculator measures your body fat by using your weight and height. Though it can indicate your risk for chronic disease by determining whether you are underweight, normal, overweight or obese, this calculator is not diagnostic of the health of an individual.
