How Much Body Fat Do You Need?

Body composition is the proportion of fat, muscle, bone, connective

tissue, and water that make up body weight. There is no single ideal body

weight. Many people place too much emphasis on how much they weigh.

The more important factor is the amount of lean body weight or percentage

of body fat of an individual. Lean body weight is the combined weight of

bone, muscle, water, and connective tissue. Each person needs some body

fat to pad or protect the body and to use some vitamins in the body. It is

important to be at a healthy percentage of body fat. Being too lean or too

fat has associated health risks. Males at a healthy level would be between

7% and 19% body fat, while females would be between 12% and 24%.

Figure 6.1 shows calculations for measuring body fat.

Individuals who have a high percentage of body fat are at risk for

being obese with the associated diseases, such as cardiovascular disease,

hypertension, and diabetes. Individuals who are too lean may delay or

affect puberty. They may also be malnourished, lacking vitamins and

minerals for good health.

Physical activity and exercise can help keep body fat at a proper level

because when you are active and move your body, you burn or expend

energy. The source of energy is found in calories from the foods you eat.

Calories that are not burned become stored by the body as fat.
