Dear VR ji, Increase your protein intake. Take Tofu(if you do not like the taste GET USED TO IT!) Next make your own Hummus(mashed garbenzo beans mixed with yogurt and salt and pepper and sesame seeds). Eat less carbohydrates. Get exercise done! I would recommend water activity in pools for senior citizens where water aerobics can be done. No impact to joints and gets good exercise. Do not worry about getting into a swimsuit..you can wear a Burkini(fully covered from head to toe) Please do not take this lightly..get yourself some activity.
