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. 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. 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. 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. 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. Binge eating can be difficult to control because many people turn to food as a way of dealing with their feelings. Keeping a food diary can be beneficial in identifying specifically what feelings are likely to trigger binge eating as well as what types of foods are consumed during a binge. Strategies can then be employed to reduce the urge to binge when the impulse strikes.
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. 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. 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.
