Information

Regular exercise and a healthy diet are crucial when it comes to controlling your weight. A weight management plan depends on whether you are overweight or underweight.

An easy way to determine your own desirable body weight is to use the following formula:

• Women: 100 pounds for the first 5 feet of height plus 5 pounds for each additional inch.
• Men: 106 pounds of body weight for the first 5 feet of height plus 6 pounds for each additional inch.
• For a small body frame, 10% should be subtracted. For a large frame, 10% should be added.

Body fat and body mass measurements are used to determine whether a person is under- or overweight. A registered dietitian or exercise physiologist can help you calculate your body fat. The recommended amount of body fat differs for men and women.

For women:

• The recommended amount of body fat is 20 - 21%.
• The average American woman has approximately 22 - 25% body fat.
• A woman with more than 30% body fat is considered obese.

For men:

• The recommended amount of body fat is 13 - 17%.
• The average American man has approximately 17 - 19% body fat.
• A man with 25% body fat or higher is considered obese.

Body mass index (BMI) is an indirect measurement of your body composition. It takes into consideration both your weight and height. BMI helps determine your risk for certain diseases, including diabetes and hypertension.

It is important to note that the terms "overweight" and "obesity" do NOT mean the same thing.

Weight management for people who have been overweight involves continued physical activity and monitoring the amount of food eaten.

UNDERWEIGHT

Anorexia nervosa and bulimia are eating disorders associated with a negative body image. Anorexia nervosa is a disorder in which people extremely limit their food intake. This results in dangerously quick weight loss, to the point of starvation. This disorder is most commonly found in adolescent females, but may also occur in males, children, and adults.

Bulimia is binge eating followed by self-induced vomiting. It's often associated with anorexia nervosa. Many people with bulimia don't lose a lot of weight, and may not get medical attention until they seek help.

Excessive intentional weight loss can cause a person to be dangerously underweight. To maintain their weight, people with eating disorders must eat enough food to prevent them from losing the weight they have gained.

To maintain your weight, you can use the following formula:

• 10 calories per pound of desirable body weight if you are sedentary or very obese
• 13 calories per pound of desirable body weight if your activity level is low, or if you are over age 55
• 15 calories per pound of desirable body weight if you regularly do moderate activity
• 18 calories per pound of desirable body weight if you regularly do strenuous activity
