Weight loss
From Free net encyclopedia
Template:SignSymptom infobox | }} In the context of physical health, weight loss is the process of losing body weight, typically by losing fat. To achieve weight loss, more calories must be expended than taken in. This can be achieved by reducing the amount of food consumed, increasing physical activity or a combination of the two.
For healthy weight loss, most experts recommend a combination of healthy eating patterns and regular physical exercise. Other methods of losing weight include use of prescribed or herbal drugs or chemicals that decrease appetite and/or increase physical activity.
Surgical options are also available. Liposuction removes targeted area of fat and tissue while bariatric surgeries can result in large weight loss by reducing the size of the stomach or reducing the absorption of food energy. Surgical and drug options may have serious side-effects.
A loss of weight can also be the symptom of some mental or physical diseases or disorders, such as anorexia nervosa, cachexia associated with cancer, AIDS or diabetes.
Weight loss can help to relieve symptoms of a variety of conditions, such as diabetes, back pain and disorders of the spine, pain in the knee or legs, and many heart conditions. For healthy weight loss, a physician should be consulted to develop a weight loss plan that is tailored to the individual.
Another key component of successful weight loss is setting a realistic goal and expectations. Many experts agree that a realistic goal for weight loss should be around 1 pound (mass) (half a kilo) per week. Adjusting your lifestyle to incorporate physical exercise and healthy eating is the best way to lose weight permanently.
