Hi Vanarchre,
I am T1D and have been Low carb now for 11 months. It has been an amazing journey which has transformed my blood sugar control and for the first time in 35 years, I have managed to put on weight and muscle.
It took me a while to learn how to eat enough calories though. The key is to take in enough fat. Sounds shocking I know but if you cut down on the carbs you have to get the energy from somewhere or you will fade away.
I eat a cooked breakfast of 2 eggs, ham and spinach or other green veg served with butter every day. I have a mixed salad with lots of olive oil, cheeses, avocado etc for lunch and perhaps a piece of roast meat with green vegetables served with butter for dinner. Sometimes snacks in between of nuts, cheese raw vegetables and some home made mayonnaise etc.
There is a lot of good information now arguing that fat is not bad for you, and never has been. See here:

I have re-learned to enjoy fat and am feeling great on it. Coffee with real cream....delicious
