What is obese? Obesity is defined as having an abnormal increase of body fat which is also called adipose tissue mass. An obese person is 20 percent or more above desirable weight. In the last decade obesity has been on the rise in both women and men. Scale weight is a total measure of bone, muscle, fluid, organs, and fat. Weight measurements reflected by the bathroom scale or compared to standard height and weight tables does not allow for weight changes which occur due to aging, exercise, or frame size. Therefore, more emphasis should be placed on body composition and healthy lifestyles with less on body weight alone. Fat distribution can influence a person's risk of disease. Fat carried around the waist and in the abdominal area, characterized by the "apple shape", is associated with an increased risk for many medical problems such as heart disease, cancer, high blood pressure, and diabetes. Fat that is mostly distributed around the buttocks and thighs is associated with a lower risk of developing these diseases. 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. 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. Many people are tempted by ads that use celebrities to tout liquid fasting diets for weight loss. Ads claim quick and easy weight loss with use of such products. Very obese patients may be referred to these types of diets. Their diets are carefully supervised by their healthcare provider. 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. To achieve lasting weight loss, commitment must be given to making real changes in eating patterns. Individuals are who not committed will gain back their weight. 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.
Drugs for treatments weight loss The medications most often used in the management of obesity are commonly known as "appetite suppressant" medications. Appetite suppressant medications promote weight loss by increasing metabolism and by decreasing appetite or increasing the feeling of being full. These medications work by increasing the serotonin and/or catecholamine - two brain chemicals that affect mood, appetite and metabolism. 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. 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. Obesity often is viewed as the result of a lack of willpower, weakness, or a lifestyle "choice" - the choice to overeat and under exercise. The belief that persons choose to be obese adds to the hesitation of health professionals and patients to accept the use of long-term appetite suppressant medication treatment to manage obesity. 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. Because appetite suppressant medications are used to treat a condition that affects million of people, many of whom are basically healthy, their potential for side effects is of great concern. Most side effects of these medications are mild and usually improve with continued treatment.
