Body composition analysis relies on BMI calculation, understanding BMR/RMR standards, and identifying the biochemistry behind fat metabolism and lipolysis.
The body mass index uses your height and weight to estimate the level of fatness in your body. For much of the population, it's a fair enough gauge as well as simple to apply and noninvasive to perform. A BMI higher than 25 indicates that you're overweight, and when it's over 30, it indicates obesity.

In physics, density is defined as an object's mass divided by its volume. Body density is essentially your compactness, or how much you weigh for every square inch of space you take up. Knowing your total body density can be helpful if you plan to use it in equations that help you estimate percent body fat.

All the biochemical processes your body does daily make up your metabolism. These processes consist of basic bodily functions -- such as pumping blood -- physical activity and digestion. The energy used to fuel these processes is measured as calories, which you get from food.

In the United States, obesity affects 35 percent of the adult population, according to 2014 statistics reported by the Centers for Disease Control and Prevention. Obesity endangers people's well-being by putting them at risk for serious health conditions.

Your body mass index, or BMI, represents an estimation of your body fat. BMI scales weigh you, just like any other scale, and ask you to input your height. The scale then performs a calculation that computes your BMI.

Your ideal weight depends on more than just your age. Your gender and height also play a role in determining a healthy size. Measurements such as body mass index and body composition analysis that aren't specific to your age help you ensure you've got a healthy ratio of lean mass to fat, too. Even if your weight is "

Body fat percentage measures the amount of lean tissue you have in relation to fat, which gives you a better picture of your health compared to your gross weight on a scale.

Measurements of your body composition, or body fat levels, give you a more complete picture of your body's healthy weight than using a scale alone.

Your body stores excess calories as body fat. Some of this fat, known as essential fat, is required for good health -- it helps with vitamin absorption, temperature regulation and, in women, childbearing. But too much body fat can pose a health risk.

Your body mass index, or BMI, is calculated using your height and weight to help your doctor estimate the amount of fat on your body. If your BMI dips below 20, he may show concern that you're underweight, and if it's below 18.5, he may diagnose you as severely underweight.
