I never lost any weight before diagnosis. Since being on insulin i do find i put weight on slightly more easily, but it is a very small change. I found i put some weight on at first because i felt incredibly weak and needed to eat to get energy. This only lasted a few months though. I think the important thing is to feel good and improve your fitness, especially the health of your pancreas. If you're eating pretty good i don't think it's worth worrying about. Small changes to weight can happen for no obvious reason anyway. Your body is possibly storing food as fat more, because you haven't been very well. For being hungry, drinking water helps me. And actually avoiding food. I find that i'm more hungry when i'm around food. The advice i get is to have small meals, but when i do that i get much more hungry than when i just avoid food and only have 2 or 3 larger meals a day. The less meals or snacks i have, the more i just forget about food altogether until i'm genuinely hungry.
