Do you have more mass than your heart can handle? Obesity is a serous problem in the US, knowing your body mass can help you make better decisions about your diet and eating habits.
Our BMI calculator will give you a quick result, without having to scan through a difficult to use BMI chart, or one of the archaic height weight charts.
Medical researchers searched for an accurate, uniform way to measure fatness for decades when in 1972, physiology professor and obesity researcher Ancel Keys published his “Indices of Relative Weight and Obesity,” a landmark study of more than 7,400 men in five countries. Keys considered the various height-weight formulas in existance and found Quetelet’s equation to be the best marker of body-fat percentage. He renamed this number the body mass index or BMI. As Singer-Vine reports, the new number caught on among researchers who had previously relied on slower and more expensive measures of body fat or on the broad and ambiguous categories defined by the insurance companies.
What is body mass index or BMI?
The body mass index otherwise known as BMI, is a simple calculation using a person's height and weight. The result typically in the range of 15 to 60 is known as the BMI or body mass index score. Most health organizations put a healthy BMI score between 19.5 and 25.0. Some people refer to this as a normal BMI.
Individuals with a body mass index under 19.5 are considered underweight. A BMI this low can indicate an undernourished individual. Your body needs "meat on your bones", to be able store energy.
If your BMI is between 25.0 and 29.9 you are considered overweight. Many athletes will fall into this range, and while it is true that their conditioning is high, there is still a lot of "mass" for the body to pump blood and provide oxygen to.
A body mass index greater or equal 30 is described as obese. Your body is under greater daily strain simply because of your weight. Your organs are not designed to work this extra hard, on a sustained daily basis.
Your body mass index is not about what weight you look the best at, it is what weight are you the healthiest with the energy stores your body needs, and the amount of tissue your organs must provide blood and oxygen to.
BMI is a useful measure of overweight and obesity. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers. BMI can be used for most men and women. It may underestimate body fat in older persons and others who have lost muscle.
Small weight loss for those with a BMI over 25 (between 5 and 10 percent of your current weight) will help lower your risk of developing diseases associated with obesity.

If you place 1 pound of muscle next to 1 pound of fat, the muscle would be 22% smaller in size.
