My research has been a bit more extensive, as I've not changed my drinking habits, but have changed my eating habits to go low(er) carb over the last 18 months.
My drink of choice is handpulled Young's bitter, or Sharps Doom Bar, and I have always had low readings 2 hours after a pint or two. I can't recall a reading above 7 two hours after beer and food, but have had readings above 9 on wine and food. Go figure. I have tested after the 2 hours occasionally, but the readings then have always dropped, so I determined my peaks were usually about the 2 hour mark.
Saturday, after a rugby day at Twickenham finished off by a Chinese meal, I managed a 6.1 2 hours later and a 5.9 next morning. :shock:
Downside was I was 3lb heavier this morning, though! :twisted:
Now, I can't stress enough. This seems to work for me. I'm not saying it will for others, but it's easy enough to test, so if it's an important part of your lifestyle....do so!
I read with envy that others seem to be able to eat as much cheese as they like without spiking. I can't; but I have my beer as a fallback, which is a decent substitute
