Obesity is on the increase worldwide. It is a complex multifactorial disease of appetite regulation and energy metabolism. Hence losing weight is not simple. A diet with too much fat is at the root of this problem. The body needs only four to six per cent of the total calories intake as fat, whereas most people consume 35 to 40 percent of total calories as fat. Vegetarians use too much oil in their diet. Consumption of sweets, ice cream, chocolates, cookies, soft drinks etc. has increased significantly as a part of modern life style. All these contain too many simple carbohydrates in the form of sugar which is an important factor in causing excess weight. Sedentary life, hypothyroidism, corticosteroids, antidepressant medications and heredity are also major causes of excess weight. The use of excessive salt in a diet tends to cause water retention in the body. Hence, it is difficult for lovers of salt to lose weight.Isolation also plays an important role in the cause of obesity. People try to fill their inner emptiness by overeating. Meditation calms down your body and mind to such an extent that you discover why you overeat. Prolonged rhythmic light exercise provides an opportunity for the body to burn fat as fuel. Research has further shown that regular light exercise reduces hunger. While counseling a person with gross obesity, one should have adequate patience and compassion. It should be explained that even a small reduction in weight leads to a large benefit in health.
