When I was first diagnosed with CF, via the sweat test, I was roughly 130 pounds, as a six-foot tall, 26 year old. I couldn’t understand why. It turned out that I was battling CF without knowing and with no treatment plan. After a decade and a half, I’ve finally gotten to a comfortable spot with my treatments, diet, medications, life-balance, and the million other things that we constantly have to deal with. I’ve tried a number of different diets while trying to get to a healthy weight.
