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. 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. 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. 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. 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. 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.
Overweight or 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. 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.
Drugs for treatments weight loss 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. 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. Maximum weight loss usually occurs within six months of starting medication treatment. Weight tends to level off or increase during the remainder of treatment. Studies suggest that if a patient does not lose at least four pounds over four weeks on a particular medication, then that medication is unlikely to help the patient achieve significant weight loss. 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. 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.
