Why people having obesity? 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. 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. 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 the holidays or when celebrating, many of us have overeaten. But some people have problems controlling their appetite and end up eating non-stop until eating is interrupted. 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.
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. 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. 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. 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.
Overweight vs. overfat 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. 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.
