Yes high fatty foods are generally considered a crucial aspect of a CFers diet. Although I think it really depends on the individual, some methods work for some, and some just don't. I have always been told as high fat as possible, and this has been working pretty good for me, even though i'm still considered underweight. And yes you are right, its because the fat isnt digested as well so we need more, and because generally CFers use up so much more energy than others just to breathe and fight infection, so we need heaps more calories - usually the easiest way to obtain those extra calories is fat! Well that's what I've always been told at least. Hope this helps.
