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.

Fasting diets for weight loss may be right for obese persons who have serious weight-related medical problems. Rapid weight loss is the primary advantage of using these diets. This may be helpful in motivating the individual to continue with the program. This may help to support lifestyle changes which are needed for continued weight loss.

Medically supervised fasts are very low calorie diets which provide from 400 to 800 calories per day. While most of these diets are low in calories, the protein provision is very high. The purpose of these diets is to promote fat loss, not muscle loss. The high protein content helps prevent large losses of muscle tissue. Electrolytes, vitamins and minerals are also supplemented.

Binge eating can be triggered by many things such as stress, depression, loneliness or anger. Food is used as a way of dealing with issues other than hunger.

During a binge, 10,000 to 20,000 calories can be consumed throughout the day. Binges usually consist of foods like cookies, candy, chips, ice cream and many other high calorie foods. Binges are often done in secret. After a binge, many of the feelings that caused the binge, like stress, may have subsided only to be replaced with feelings of guilt and lack of self-control.

Bulimia nervosa is an eating disorder that is estimated to be present in up to 5 percent of teenage and young adult women. It is characterized by binge eating followed by purging and other behaviors such as vomiting. Laxatives, diet pills, water pills, exercise or fasting may also be used.

The following guidelines have been developed that may help control binge eating: - Eat only at established meal times. - Avoid keeping foods around that may trigger bingeing. - Avoid fad or very restrictive diets. - Keep a food diary and log to assess what prompted the binge.

Binge eating can be difficult to control because many people turn to food as a way of dealing with their feelings. Keeping a food diary can be beneficial in identifying specifically what feelings are likely to trigger binge eating as well as what types of foods are consumed during a binge. Strategies can then be employed to reduce the urge to binge when the impulse strikes.

The most recent drug in the fight against obesity is Xenical. A new class of non-systemic anti-obesity drug called lipase inhibitors which act in the gastrointestinal tract to prevent the absorption of fat by about 30 percent. Drugs in this class do not achieve their effect through brain chemistry or central nervous system stimulation. In other words, Xenical is not an appetite suppressant or metabolic inducer.

Brand names of the most effective prescription diet medications on the market today are: Phentermine, Adipex-P, Fastin, Ionamin, Bontril, Plegine, Tenuate, Xenical.

Several appetite suppressant medications are available to treat obesity. In general, these medications are effective, leading to an average weight loss of five to twenty-two lbs. above that expected with non-drug obesity treatments.

When considering long-term appetite suppressant medication treatment for obesity, you should consider the following areas of concern and potential risks. Currently, all prescription medications to treat obesity are controlled substances, meaning doctors need to follow certain restrictions when prescribing appetite suppressant medications. Although abuse and dependence are not common with non-amphetamine appetite suppressant medications, doctors should be cautious when they prescribe these medications for patients with a history of alcohol or other drug abuse.

However obesity, is more appropriately considered a chronic disease than a lifestyle choice. Other chronic diseases, such as diabetes, and high blood pressure, are managed by long-term drug treatment, even though these diseases also improve with changes in lifestyle, such as diet and exercise. Although this issue may concern physicians and patients, social views on obesity should not prevent patients from seeking medical treatment to prevent health risks that can cause serious illness and death.
