Many people may actually be overfat but not overweight. Fat can also be hidden throughout the body. A person may be overfat without the appearance of being overweight. As we age, muscle tissue is replaced with fat. This occurs despite regular exercise. When the muscle's capacity to store fat is exceeded, excess fat is then stored outside the muscle, around body organs and under the skin. The fat that is now being added to the body results in the person becoming overfat and overweight.

Many people are motivated to diet by wanting to be thin and attractive like the models we see everywhere - on TV and in magazines. What is far more important is that a leaner body reduces the risk for certain diseases. Studies show that a 20 percent increase in body weight increases the risk for heart disease, high blood pressure and diabetes.

Body composition describes the percentages of fat, muscle and bone in your body. Many experts think men's bodies should be between 12 to 18 percent fat, while women's should be 18 to 22 percent fat. Knowing your body composition can help you design a fitness program to build more fat-burning muscle. Resolving to change your body composition and not simply to lose weight, can improve your overall health.

The risk of developing weight associated medical problems increases if the majority of body fat is located in the abdominal area. This risk decreases if body fat is primarily located in the hips, buttock and thigh region. Percentage of body fat can also be determined with:
* underwater body weighing (or hydrostatic weighing) ,
* ultrasound measurements,
* skinfold measurements, and
* bioelectrical impedance.

Height and weight tables are generally used to determine how person's weight compares to a standard. However, weight in these tables is an overall measure of all components of the body. Individuals may differ in muscle, frame size and percentage of body fat. The waist to hip ratio of body composition assessment provides information on where the majority of body fat is located.

Call your local YMCA or gym to see if they offer body composition testing.
