My Dad is 80 years old and is getting frail and dangerously thin. My Mom who is 76 is not really interested in cooking. They don't like Meals on Wheels. Does anyone have any suggestions of fattening, healthy snacks/meals I can load up his refrigerator with? The conundrum is, my Mother is getting too thick around her mid-area, which I understand is dangerous for heart-health. Any feedback would be appreciated!
