1). Treatment for obesity■1.Obesity can become a chronic lifelong condition caused by overeating，physical inactivity，and even genetic makeup.No matter what the cause is，however，obesity can be prevented or managed with a combination of diet，exercise，behavior modification，and in severe cases，weight-loss medications and surgery.■2.The most common and conservative treatment for obesity tilizes a nutritionally balanced，low calorie diet.Most health-care professionals and commercial weight-loss programs recommend diets consisting of 1，200 to 1，500 calories per day，usually in the following proportions：60 percent carbohydrate，30 percent fat，and 10 percent protein.■3.Caloric restriction alone will not produce long-term weight loss.While the data from studies on the effect of exercise for short-term weight loss are contradictory，research clearly indicates that regular exercise is the single best predictor for achieving long-term weight control.Regular exercise will also improve some of the medical conditions associated with obesity，including elevated blood cholesterol，hypertension，and diabetes mellitus.■4.A renewed scientific and commercial interest in weight-loss medications was prompted by the approval from the Food and Drug Administration (FDA) of the appetite suppressant dexfenfluramine (右芬氟拉明) in 1996.Dexfenfluramine was the first weight-loss medication approved in the United States in over 20 years and the first ever approved for maintaining weight loss.■5.Over a six-month period，weight-loss medications may result in a 10-percent body weight reduction.Weight loss slows or stops after six months，and discontinuing medication usually causes weight regain.Many experts recommend that medications for weight control should be used continuously，like medications for diabetes mellitus and hypertension.Unfortunately，few studies have examined the consequence of long-term use of weight-control medications.■6.Surgery may be a weight-loss option for patients who are severely obese and suffer from serious medical conditions due to weight.There are two accepted surgical procedures for reducing body weight：gastroplasty(胃成形術(shù))and gasric bypass(胃旁路術(shù)).Although these two procedures use different surgical methods，they both reduce the stomach to a pouch (小袋) that is smaller than a chicken′s egg，drastically limiting the amount of food that can be consumed at one time.Surgery is not without risk and should be performed by skilled surgeons who also provide patients with a comprehensive program for long-term weight control.Patients receiving weight-loss surgery should be provided with a(n) ( ) program for long-term weight control.
