I'm on metformin 500mg 2 tabs twice daily and 1 10mg dapagliflozin. I used to take gliclazide before the dapagliflozin but I did so well for a while that I was taken off it, if you can believe it. I'm 64 and started to gain weight at the age of 5. My whole life has been a struggle weight wise. But I keep trying. I'm 5' 2" 157.5 cm and currently weigh 12st 10lbs (80.74 kg) but at my heaviest many years ago, I went up to 18 stones(114kg). I've hovered around my current weight now for a few years. Sometimes I'm a bit less, but fortunately, never any heavier. I really don't think that I will ever make my ideal weight as, as I've said earlier. I am very greedy and seem to have almost zero resistance. I gave up smoking 20 years ago and alcohol 18 months ago. But never mastered the food addiction, and for me, food really is an addiction. I will however keep trying.Obviously the 3 wheat biscuits are more than the portion size advised for non-diabetic people so definitely not great for a diabetic. I think some people here get away with 1 Weetabix plus natural yogurt and berries.
I wasn't aware of the Mountain Joes but you have to learn to look at the total carb content of whatever you eat, not just the sugar
On the whole however, if does not seem that you are eating many carbs and I certainly don't think you can consider it gluttony having 2 apples and some cheese for lunch. It sounds like you are quite active with your job, so aside from some small tweaks to your diet like reducing the quantity of wheat biscuits and doing some testing and looking for a better option to replace the Mountain Joes (Maybe try the Nature Valley Protein Bars as they are just 10g carbs per bar. so that is a 50% reduction straight away, although personally I am not a fan of these highly processed and sweetened bars anymore, I don't think there is much room for improvement and you may need more medication.
Did you tell us what medication you are currently on? If so, apologies, I must have missed it.
