My elderly father is having a hard time keeping up an appetite and his doctor prescribed megesnol acetat (spelling is not correct) but the side effects are not good, he has health issues heart, blood pressure. He is 6 1 and only weighs about 150 lbs. he is 80 years old and plays golf once a week (uses a cart to get around the golf course) and mows the lawn and general light yard work. To avoid taking this medication what are good foods he good get a lot of calories from to help him? He basically feels fine just no appetite. He does not like ensure which was my first suggestion.
