Newbie firstly there is ‘no grade’! We are all individual and things happen at different times. Your HbA1c was very high and to get it down by 50% in such a short space of time is really good.
I think one of the great misconceptions is that ‘weight’ is the magic secret to reversing T2. Weight is a factor but carbs are the real secret. I’m sure you’ve probably heard of TOFIs, Thin on the Outside Fat on the Inside. So, yes you can be thin (on the outside) but still have diabetes. The real secret is controlling the carbs. Simple carbs are the real problem, colour isn’t that important. Brown rice is better than white but still high in carbs. Lots of ‘brown’ bread is really not much better than white. Even some fruits are high carb such as pineapple, mango and other ‘exotic’ fruits, and even apples, for example having roughly 20g of carbs in a medium one. Sorry if I’m ‘preaching to the converted’ but concentrate on the carbs before the calories. Most people try to stay at lower than 50g a day but some who follow a keto diet go down to 20g. I’ve never really managed to get that low but still manage to control my blood sugars. Trial and error.
I don’t know about an optimum time for eating your last meal in the evening but I personally stop eating by 7pm when at home but if we’re away or out it’s later and I can’t say that I’ve noticed much difference in my blood sugars.
Hope everyone is having a good weekend.
