Thanks for the apology, but you got me quite irritated with your first comment. It was like saying to a paraplegic in a wheelchair to man up and hit the gym because there is only so much you can do with a wheelchair... Dreadful.

Just to add a bit of a positive spin on this: even type-1 diabetics could take measures to both improve their health and reduce the amount of insulin they require.

I consider myself moderately overweight at this point (maybe 10-15kg). If I lost weight, I could reduce the baseline amount of insulin I need every day, thus reducing the amount of insulin overall that I need to pay for.

I also fully acknowledge that, upon getting an insulin pump (16 years ago), I instantly became aware that I had much more freedom to eat what I want, when I wanted and thus, put little effort to cutting back on sugar outside of switching to diet drinks. If I were to switch to a low-carb diet, or no carb (which is admittedly very hard, I've tried), I could further reduce my insulin costs.

Personally (keep in mind these numbers depend highly on each individual), if I got my weight down 10kg, and ate < 100g of carbohydrates per day, I could theoretically only require ~35-40 units of insulin per day. At 40 units, I would only need ~1.35 vials of insulin per month. Ballparking, I'd say my current rate is likely around 2 vials per month.

You still need to have carbs in your diet, it wouldn't be healthy otherwise. Especially if you practice a sport.

I eat whatever I want (mostly pasta usually) and I need 20 units a day at most. (100 units/ml dosage).
