The diagnoses are quite variable and may include reduced food intake, organic causes,or psychological disorders; however, among many older adults, no obvious medical cause can be identified. A variety of nonpharmacologic interventions may improve energy intake and lead to weight gain. In some cases, access to quality nutrition is the main issue. The most common approach to the treatment of weight loss among older adults is consumption of high-energy/high-protein oral supplements between meals as a means of increasing daily energy intake. The role for pharmacotherapy remains limited at present....Avoid junk foods,add extra calories to your diet,have 4 to 5 meals rather than large 3...add protein rich foods and healthy fats to diet for e.g..egg white...add fibre rich foods like green leafy veggies,carrots,Apple, etc. Add green tea to your diet .you have to eat more foods high in amino acids,calcium, zinc, iron, copper and magnesium...do regular exercise without failure......consult dietitian for further details

Weight gain is a slow an steady process. Healthy muscle gain is what is required at your age A balanced diet will promote muscle  and over all development. In case of non-vegetarians, there are lots of option to select from. For pure vegetarians there are many combinations of foods that promote muscle growth. I do not favour protein supplements unless you are a sports person. Pulses, Soya, cruciferous vegetables, dairy products and whole cereals promote muscle gain. Along side proper exercise and a healthy lifestyle aids in overall developmemt.
