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.

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.

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.

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 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.

Overfat or overweight?

Studies show that a 20 percent increase in body weight increases the risk for heart disease, high blood pressure and diabetes.

Knowing your body composition can help you design a fitness program to build more fat-burning muscle. Resolving to change your body composition and not simply to lose weight, can improve your overall health.

Height and weight tables are generally used to determine how person's weight compares to a standard. However, weight in these tables is an overall measure of all components of the body. Individuals may differ in muscle, frame size and percentage of body fat. The waist to hip ratio of body composition assessment provides information on where the majority of body fat is located.

Drugs for treatments weight loss

Obesity is a chronic disease that affects many people and often requires long-term treatment to promote and sustain weight loss. As in other chronic conditions, such as diabetes or high blood pressure, long-term use of prescription medications may be appropriate for some individuals

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.

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.

Most studies of appetite suppressant medications show that a patient's weight tends to level off after four to six months while still on medication treatment. While some patients and physicians may be concerned that this shows tolerance to the medications, the leveling off may mean that the medication has reached its limit of effectiveness. Based on the currently available studies, it is not clear if weight gain with continuing treatment is due to drug tolerance.

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.

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.
