There are prescription medications, foods, and other things to help increase the appetite, and some even taste.
Megace, Marinol
Caffeine, wine
Fat, oil, sugar, fat and sugar combined even more so, and reason their in snacks
Appearance of food, color of plate, utensils, room ambiance
The senses, sight, smell, hearing, tasting, memory
Watch the food channel, read cooking magazines, books.
Eat foods familiar not unfamiliar
I hope this helps
