Why people fat? 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. 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. 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. 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.
Diet 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. 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. Several appetite suppressant medications are available to treat obesity. In general, these medications are effective, leading to an average weight loss of five to twenty-two lbs. above that expected with non-drug obesity treatments. 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 or 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. 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. 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.
