I’m recently diagnosed T2, currently experimenting with Libre. Not massively fit, but like to swim and walk.
I’ve been conscious for a while that my lines up and down the pool in the morning spikes my blood glucose, which I discovered accidentally when testing with a meter. I was a bit suprised as I hadn’t realised that exercise had this effect. I usually do about 30 mins, its not what I would call intense but it raises the heart rate and makes me feel good. I’m also getting a consistent dawn liver dump which gives a spike in the morning, taking me this morning to 6.7. On days without any exercise, breakfast (even a low carb one) will send my BG up again, although to be fair, it does come down again pretty quickly and within 2 hours its down to where it was before and sometimes lower.
Question is really what should I eat post exercise? I’m conscious that the BG level is already high, it doesn’t need any more fuel on board, and sometimes my exercise spikes will leave BG high for a long time. It seems to be different to the meal spikes in that it doesn’t dissipate as quickly. Is this because the fuel is coming from the muscles themselves? I understand that muscles store sugar too, which gets released upon exercise.
Prior to diagnosis I would use my morning swim as an excuse for a full English afterwards, but I’ve had to cut out the sourdough bread bit . The rest is probably OK ish in terms of carbs/protein, although the sausages did horrible things yesterday to my BG numbers.
I don’t want to send my BG up even higher with breakfast afterwards, but it’s usually a bit too long before lunch so I need something. I’m using the free Libre to test various things on my system, but all suggestions gratefully received.
