Body Mass Index






Body Mass Index (BMI)

Body Mass Index (BMI) is the most convenient and accurate way to calculate a person's body fat. The formula takes into account weight and height, to provide a quick measure of a person's health status. An individual should have a BMI between 18.5 and 24.9 to be considered healthy. A high BMI can indicate unhealthy levels of body fat. Low BMI may indicate that an individual is underweight, malnourished, etc.

If you're wondering what your Body Mass Index means, it's a way for doctors to establish whether or not an individual is in a healthy weight range.

To calculate BMI, the following formula applies: BMI = ([Weight in pounds]/[Height in inches]^2). Then multiplying by a conversion factor of 703.

People with a high BMI are at higher risk for developing type 2 diabetes, hypertension, and coronary artery disease. These conditions lead to the development of other chronic illnesses like dementia and cancer. It has been found that people with a high BMI suffer from more depression than those with normal weight.

One of the most important things you can do for your long-term health is to maintain a healthy weight. Being overweight or obese increases the risk of many chronic illnesses such as heart disease, type 2 diabetes, and cancer. Not only that, but it also causes an increase in mortality rates and a reduction in life expectancy. The good news is that you don't have to be too thin to stay healthy - any BMI between 18 and 24 is considered healthy.
