I am curious as to whether or not anyone who is overweight and borderline glucose intolerant has ever tried to lose weight by giving up sugar, bread, pasta and cereal. I know we are supposed to have a lot of calories and a balanced diet, but I am having a difficult time losing weight. I know several people (who do not have CF) who have lost weight fairly comfortably on a diet of protein, fruit and vegetables. It sounds like a pretty healthy way to jump-start weight loss.
