I was diagnosed just before last year, which did limit my food enjoyment somewhat. However, several months being disciplined eating 100-120g carbs a day with plenty of exercise have seen 6 stones disappear together with good BG control (Hba1c 32, FBG average 4.3) without medication. I now eat 170-180g carbs a day so have plenty of scope for food fun over the period without busting my diet.
My biggest miss last year was panettone, served with a generous glass of marsala, so this year I will be treating myself a bit. I bake it myself so will reduce sugars a bit (I do still like sweet food but my definition of sweet has changed with my taste buds and I am now very sensitive to any sugar).
Even so, a reasonable piece will have about 50g of carbs, so I will have this just before a bracing walk of an hour or so. Extra carby food will be balanced with all the meat and cheese snacks to keep overall food levels similar.
