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.
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.
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.
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.
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.
Studies show that a 20 percent increase in body weight increases the risk for heart disease, high blood pressure and diabetes.
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.
