What is obesity 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. 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. Research points to differences in appetite control and energy expenditure. It is important for obese people not to hold themselves responsible for their condition. 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. 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. 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.
Weight loss drugs 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. 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. 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. 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. 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.
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. Studies show that a 20 percent increase in body weight increases the risk for heart disease, high blood pressure and diabetes. 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.
Definition explainingFDA
- Food and Drug Administration: A government agency that oversees public safety in relation to drugs and medical devices. The FDA gives approval to pharmaceutical companies for commercial marketing of their products.
Fat blocker
- Drugs that block the absorption of fat or calories, and lose substantial weight.
Overweight
- Weighing more than is normal, necessary, or allowed, especially having more body weight than is considered normal or healthy for one's age or build.
Appetite
- An instinctive physical desire, especially one for food or drink. Decreased desire to eat is termed anorexia, while polyphagia (or "hyperphagia") is increased eating. Disregulation of appetite contributes to anorexia nervosa and cachexia, or oppositely, overeating.
