Location of body fat
   Research suggests that the location of body fat also is an important factor in health risks for adults. Excess fat in the abdomen (stomach area) is a greater health risk than excess fat in the hips and thighs. Extra fat in the abdomen is linked to high blood pressure, diabetes, early heart disease, and certain types of cancer. Smoking and too much alcohol increase abdominal fat and the risk for diseases related to obesity. Vigorous exercise helps to reduce abdominal fat and decrease the risk for these diseases. The easiest way to check your body fat distribution is to measure around your waistline with a tape measure and compare this with the measure around hour hips or buttocks to see if your abdomen is larger. If you are in doubt, you may wish to seek advice from a health professional.

Problems with excessive thinness
   Being too thin can occur with anorexia nervosa, other eating disorders, or loss of appetite, and is linked to menstrual irregularity and osteoporosis in women, and greater risk of early death in both women and men. Many people - especially women - are concerned about body weight, even when their weight is normal. Excessive concern about weight may cause or lead to such unhealthy behaviors as excessive exercise, self-induced vomiting, and the abuse of laxatives or other medications. These practices may only worsen concern about weight. If you lose weight suddenly or for unknown reasons, see a physician. Unexplained weight loss may be an early clue to a health problem.

If you need to lose weight
   You do not need to lose weight if your weight is already within the healthy range on the chart on the previous page, if you have gained less than 10 pounds since you reached your adult height, and if you are otherwise healthy. If you are overweight and have excess abdominal fat, a weight-related medical problem, or a family history of such problems, you need to lose weight. Healthy diets and exercise can help people maintain a healthy weight, and may also help them lose weight. It is important to recognize that overweight is a chronic condition which can only be controlled with long-term changes. To reduce caloric intake, eat less fat and control portion sizes. If you are not physically active, spend less time in sedentary activities such as watching television, and be more active throughout the day. As people lose weight, the body becomes more efficient at using energy and the rate of weight loss may decrease. Increased physical activity will help you to continue losing weight and to avoid gaining it back.
   Many people are not sure how much weight they should lose. Weight loss of only 5-10 percent of body weight may improve many of the problems associated with overweight, such as high blood pressure and diabetes. Even a smaller weight loss can make a difference. If you are trying to lose weight, do so slowly and steadily. A generally safe rate is ½-1 pound a week until you reach your goal. Avoid crash weight-loss diets that severely restrict calories or the variety of foods. Extreme approaches to weight loss, such as self-induced vomiting or the use of laxatives, amphetamines, or diuretics, are not appropriate and can be dangerous to your health.

Weigh regulation in children
   Children need enough food for proper growth. To promote growth and development and prevent overweight, teach children to eat grain products; vegetables and fruits; lowfat milk products or other calcium-rich foods; beans, lean meat, poultry, fish, or other protein-rich foods; and to participate in vigorous activity. Limiting television time and encouraging children to play actively in a safe environment are helpful steps. Although limiting fat intake may help to prevent excess weight gain in children, fat should not be restricted for children younger than 2 years of age. Helping overweight children to achieve a healthy weight along with normal growth requires more caution. Modest reduction of dietary fat, such as the use of lowfat milk rather than whole milk, are not hazardous. However, major efforts to change a child’s diet should be accompanied by monitoring of growth by a health professional at regular intervals.
