Obesity
Obesity is an excess of body fat frequently resulting in a significant impairment of health. It is a very importanat health problem of not only developed nations but a large part of population of developing countries too are facing obesity related health hazards.

 

Obesity is defined as a body mass index above 30 kg/square meter.
Weight gain may confer increased health risks even if the BMI does not exceed 25. In women a weight gain of more than 5 kg (11 lb) is associated with increased risks of diabetes and heart disease, and in men any weight gain after age 25 appears to carry increased health risks.
The American Heart Association has declared obesity a "major risk" factor in heart attacks, adding it to a list that includes smoking, high blood pressure, high cholesterol and a sedentary lifestyle. Previously, the heart association listed obesity as a "contributing risk" factor for heart attacks. Obesity itself has become a lifelong disease and not a cosmetic issue. it is becoming a dangerous epidemic. Obesity needs to accepted as a chronic disease, just like high blood pressure or high blood cholesterol. Studies have shown that gradual weight losses of between 5 and 10 percent of body weight can decrease blood pressure and cholesterol levels, which are often higher in obese people.
