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. Obese people should be evaluated for medical consequences of their obesity. Motivated persons are encourage to enter medically supervised treatment programs that use a multidisciplinary approach to 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. Proper use of these diets requires close monitoring and follow-up. To promote lasting weight loss, lifestyle changes must be made by the dieter while on the fast. 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. Binge eating is like bulimia, but does not include purging behaviors. A diagnosis of binge-eating disorder is made when a person binges an average of two days per week over a six month period. 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.
Appetite suppressant medications help weight loss by diminishing appetite or increasing the feeling of being full. These medications diminish appetite by rising serotonin or catecholamine two brain chemicals that affect appetite. Appetite suppressant medications are used with a course of behavioral treatment and dietary counseling, designed to help you make long-term changes in your diet and physical activity. Brand names of the most effective prescription diet medications on the market today are: Phentermine, Adipex-P, Fastin, Ionamin, Bontril, Plegine, Tenuate, Xenical. People respond differently to appetite suppressant medications, and some people experience more weight loss than others. Some obese patients using medication lose more than 10 percent of their starting body weight- an amount of weight loss that may reduce risk factors for obesity - related diseases, such as high blood pressure or diabetes. Maximum weight loss usually occurs within six months of starting medication treatment. Weight tends to level off or increase during the remainder of treatment. Studies suggest that if a patient does not lose at least four pounds over four weeks on a particular medication, then that medication is unlikely to help the patient achieve significant weight loss. Over the short term, weight loss in obese individuals may reduce a number of health risks. Studies looking at the effects of appetite suppressant medication treatment on obesity-related health risks have found that some agents lower blood pressure, blood cholesterol, triglycerides (fats) and decrease insulin resistance (the body's inability to use blood sugar) over the short term. Long-term studies are currently being done to determine if weight loss from appetite suppressant medications can improve health. 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. Appetite suppressant medications are not "magic bullets", or a one- shot fix. They cannot take the place of improving one's diet and becoming more physically active. The major role of medications appears to be to help a person stay on a diet and exercise plan to keep off the weight they lose.
Many people are motivated to diet by wanting to be thin and attractive like the models we see everywhere - on TV and in magazines. What is far more important is that a leaner body reduces the risk for certain diseases. Studies show that a 20 percent increase in body weight increases the risk for heart disease, high blood pressure and diabetes. Body composition describes the percentages of fat, muscle and bone in your body. Many experts think men's bodies should be between 12 to 18 percent fat, while women's should be 18 to 22 percent fat.
