Well if you happen to be a really low carber, that's about half of one days carbs in one hit!
I give serious thought to any snack that's greater than 10g - can I be arsed to bolus for this? is it really that nice I want to be bothered to that? is it really worth it?
Now this next bit is probably rhetorical but her goes -
I know I'm T1 and not partic overweight, but if T2s considered how a T1 would need to deal with that snack, which is after all the same as what they are asking their own pancreas to do for them every time they eat - would they reconsider?
I sort-of treat insulin like money ! Have I got enough money in my purse to buy this whatever it is willy nilly, or would I rather save my pennies and wait till I have enough to buy a bigger/better foodstuff in the future? A bit like trying to persuade a small child not to use his pocket money to buy trash today, when he could save it, put it with next week's and get summat more desirable and durable?
And sometimes I just go Hang it, I'm having THAT and bolus for it anyway, LOL
