Calculate Your BMI (Body Mass Index)
The Body Mass Index is a poor measurement and a controversially inaccurate indicator to assess health. An ideal BMI (which the measurement considers to be healthy) is between 20.5 and 21.5. However, it makes absolutely no distinction between body weight from muscle and body weight from fat which labels a broad segment of the athletic and similar healthy populations as overweight and obese. It is limited in its ability to predict deaths caused by heart attacks or strokes (yet it's still used by Physicians). High BMIs (35 and over) are linked to increased risk of cardiovascular events but not to increased mortality overall. BMIs less than 20 are linked to increased risk of cardiovascular events AND to total mortality. More

Calculate your BMR (Baso-Metabolic Rate)
Your BMR, or basal metabolic rate (metabolism), is the energy (measured in calories) expended by the body at rest to maintain normal bodily functions. This continual work makes up about 60-70% of the calories we use and includes the beating of our heart, respiration, and the maintenance of body temperature. More

Ideal Body Weight and Mass
The use of ideal body weight and mass calculators may serve as rough guidelines to assess your body-type. However, they may be extremely inaccurate to those who are athletic, engage in weight training programs, or are simply genetically predisposed to larger (or much smaller) body-types. For this reason it is advisable to use a 10-20% range above and below your result. Both Male and Female calculators are available. Men may also prefer a more experimental method of assessing body measurements by trying a calculator based on wrist circumference called Ideal Male Mass.
