    I’m not an expert, but I’ll bet when you bolus ‘normally’, in this case I mean not into a muscle that insulin doesn’t get used up faster when you exercise. I don’t know how it works, but exercising makes your body use the insulin more effectively. I believe it does this without using the available insulin up any faster. It’s like there’s a super sale on glucose molecules when you exercise. One insulin molecule can take on 10 glucose molecules, instead of the normal 3. I’m making the ratios up, but that’s how I think about it.

    I really do wish someone would explain how exercising helps your muscles use up blood glucose even when you only have basal insulin on board. I’d love to understand a bit of the biology behind that.

    Speaking of BG and exercise, I need to go swim….
