Hi
@rowan
How fit and active are you?
You see, while you are finding your feet with the low carb thing, you are bound to make the odd mistake - noodles, frozen macaroni cheese, etc - but there is a relatively simple way of getting blood glucose down. It can also reduce a spike.
Basically, it's exercise. It all depends on your fitness level, and how active you can be.
I'm built for comfort, not speed, and my idea of violent exercise is a few flights of stairs. Someone else might walk briskly for a few minutes, or climb on an exercise bike. A fit person would probably need longer, harder exercise.
Please don't think I'm suggesting you flog yourself to exhaustion. Simply moving, consistently for a while will help. The best thing to do is try it out for yourself, and see if climbing stairs or hoovering, or popping out to fetch a pot of cream
from the corner shop, will help. Test before and after eating, then before and after exercise.
My personal experience is that 4-6 flights of stairs bring my BG down a bit (say from 8 down to 6).
This is great.
But if I am still digesting the food, my BG will then start to rise again.
So I can choose to go for a longer walk (to cancel out the BG rise)
Or I can wait a few minutes and go up the stairs again...
Probably worth mentioning that violent exercise on a full stomach really ain't a good idea, and violent exercise will briefly raise BG anyway, so keep it moderate, and see if it works for you.
