My son has always carried extra weight since his adenoids were removed when he was about 5. I wish I knew then...although I'm not sure what choice I would have made differently. He had "profound" hearing loss due to water on his ear, though not sick. He was very thin and had circles under his eyes. Dr. said instead of doing allergy testing, he thought son's immune system, that is his adenoids, were "overly active". I wonder now if this was a clue that he had an immune system on overdrive. At any rate, removing the adenoids and tubes removed resulted in an eating machine. He loves to eat, loves carbs. My husband and I are lower ( not no-carb, just lower) healthy eaters, and we model this to him and have all along. Exercise, eat well rounded, go easy on the carbs and eat the right type of carbs. So while in the hospital and since, the CDE's are saying he needs a significant amount more of carbs than we were previously feeding him. They suggest 60 - 70 per meal plus snacks. We were told that he is growing (he is but slowly right now) and that not feeding this amount of carbs could also affect brain development. At Endo appt this week, Endo said the way we were eating before was fine, and that yes, you need some carbs, but more of the 40-30-30 rule of carb-fat-protein. He did not think we have to have quite so many carbs. Wondering what advice you might give. Son is thinking that at least diabetes has the benefit of receiving more carbs per meal. If an adult chooses to, I can see that a lower carb diet would be advantageous, but don't want to hold back on carbs if it will hurt development. There is even a book (Bernstein, I think) that recommends low carb. He is right now 5' tall, 122 lbs.
