An obese person is 20 percent or more above desirable weight. In the last decade obesity has been on the rise in both women and men. Scale weight is a total measure of bone, muscle, fluid, organs, and fat. Weight measurements reflected by the bathroom scale or compared to standard height and weight tables does not allow for weight changes which occur due to aging, exercise, or frame size. Therefore, more emphasis should be placed on body composition and healthy lifestyles with less on body weight alone.
Fat distribution can influence a person's risk of disease.
Fat that is mostly distributed around the buttocks and thighs is associated with a lower risk of developing these diseases. As much as 50 to 75 percent of obesity has genetic influences. Just what those genetic influences are that affect body weight have not been identified. Research points to differences in appetite control and energy expenditure. It is important for obese people not to hold themselves responsible for their condition.
