OK, I have some experience and a lot of sympathy with this topic. I have been T1 since the age of 8, with a T1 mum and (in old age) a T2 dad, so not the greatest of genetic backgrounds.
Given that I am prone to insulin resistance, and am a lot more insulin resistant than I was twenty years ago, I have had to make some decisions. Firstly, my bg comes first. Under
no circumstances will I ever try to lose weight by skimping on or skipping insulin. That way lies DKAs, complications and premature death. Insulin is my best friend, it's kept me alive and well for 51 years.
I am currently sitting at overweight but not obese, and in an ideal world would like to lose 15kg. The only thing that seems to stop me from gaining weight is to restrict my carbs, this plus exercise tends to reduce my insulin resistance. (If I also give up alcohol and cheese I probably lose about 1kg a week, but I rarely have the will power to do both at the same time.
) Note that I don't drastically restrict my carbs, probably normally on around 100g a day, but it works for me.
As regards the exercise, I only wish I'd prioritised this at
@EmlynV 's age, and not waited till I was in my late 40s. It makes a massive difference to my health and well being, and reduces my insulin needs by a little as an extra bonus. Likewise with the carb restriction, I don't go overboard on this, but do walk my dog every day, plus a couple of sessions a week at the gym (I'm sure they aren't necessary if you've got the will power to take enough exercise at home, but I am naturally sedentary so find a gym work out makes a big difference.)
