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. 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. 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.
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. Brand names of the most effective prescription diet medications on the market today are: Phentermine, Adipex-P, Fastin, Ionamin, Bontril, Plegine, Tenuate, Xenical. 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.
Many people may actually be overfat but not overweight. Fat can also be hidden throughout the body. A person may be overfat without the appearance of being overweight. As we age, muscle tissue is replaced with fat. This occurs despite regular exercise. When the muscle's capacity to store fat is exceeded, excess fat is then stored outside the muscle, around body organs and under the skin. The fat that is now being added to the body results in the person becoming overfat and overweight. The risk of developing weight associated medical problems increases if the majority of body fat is located in the abdominal area. This risk decreases if body fat is primarily located in the hips, buttock and thigh region. 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.
