Hi
@Siorac99, well done on your good fbgs and weight loss. Your diet and exercise should get you a lower HbA1c at next test.
The only way you will know if eating chocolate and cake will raise your bgs is to continue testing.
I have the occasional high carb/sugar treats too, which don't usually affect my readings too much. The danger is that one 'treat' can lead to another and I could let carb creep raise my bgs to diabetic levels again.
After the initial shock at diagnosis I lost about 3 stone and reduced my HBa1c to 39. But becoming complacent and eating more carby stuff again my weight has crept up, and so has my bg readings.
I am still 18 lbs below my weight at diagnosis, and my last HbA1c in October was up to 46, still less than the 47s I was getting before diagnosis. But I know I need to be careful not to go any higher.
