What is 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. 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. 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. 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. 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. 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.
Fat blocker drugs 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. While the FDA regulates how a medication can be advertised or promoted by the manufacturer, these regulations do not restrict a doctor's ability to prescribe the medication for different conditions, in different doses, or for different lengths of time. 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. 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. 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. 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 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. 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. 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.
