"BTW carbs are probably the most unhealthy aspect of the current Western diet so by keeping them under control you should be having a healthy diet."
Good job Mum's gone to Iceland then! Full of more healthy options there.......McDonalds, chip shops, energy drinks etc etc. Is Italy in the midst of an obesity epidemic? I live in Scotland, the second fattest nation around apparently. I don't think carbs are to blame.
Any dietician, doctor or do gooder will go with the "have plenty of carbs" advice as it's the national guideline. They will also go with the "exercise regularly" advice and "eat in moderation" advice. As a T1 I do not suffer from an inability to handle carbs properly. I suffer from not being able to produce insulin. I consider my diet very healthy and I do eat more than the recommended amount of carbs. I eat more than I probably should and without the exercise I do I have no doubts I'd put a lot of weight on.
Diet is only one part of the bigger picture. To the OP - the best thing you can do is try your **** hardest to stick to the healthy diet and not look for any simple solutions as they normally have a sting in the tail somewhere. Your motivation? Well, your T1 now and looking after yourself properly is essential. You have no reason not to lead the rest of your life perfectly normally and as healthily as anyone else.
