Diet plays an important role in building up health for gaining weight. Under weight persons should eat frequent small meals, as they tend to feel full quickly. The number of calories it contains measures the weight building quality of a food. To gain weight, the diet should include more calories than are used in daily activities so as to allow the excess to be stored as body fat .The allowance of 500 calories in excess of daily average needs is estimated to provide for a weight gain of half a kilogram weekly. All refined foods such as products containing white flour and sugar should be avoided as they destroy health.
Regular exercises like walking ,dancing ,yoga, meditation and massage are also important as they serve as relaxants, reduce stress, and induce good sleep.
