I'm sorry to say but all of the ideas in this thread are HORRIBLE, with the exception of rmotion. Eat all that junk food, get CFRD one more thing to add to the list. Just because we have CF doesn't mean we can eat whatever we want. That's a huge misconception that CF doctors portrayed to me at least as I grew up. This is the wrong attitude to have. Too many simple carbs is asking for trouble, and trouble is what we all got. We need to eat more like bodybuilders. The American heart association is now going back on years of incorrect data to say that bodybuilders from the 30s have been right all along. This idea that we should eat junk food and piles of it has got to end. HFCS is the devil, write that down now. Then eliminate it from your diet. You will be much better off. Start taking in MCT's and good things, you will gain weight and feel better than you ever have in your life. Look at people in Europe you know why they are not a bunch of fatasses? Because they don't live in a nations like Americans where foods are chalk full of poisons. I may sound like a conspirator theorist, but the truth has been coming out for years and it's not going to stop. So keep eating crap tons of ice cream and Krispy cream donuts, don't wonder why you got CFRD later, or can't gain weight and feel like garbage 24/7 of your life. The last thing I want to say is proper high quality PROTEIN, chicken breasts and turkey people! First thing in the morning!
