Beer is just liquid toast - test

For various reasons, including inconclusive fasting readings after beer the previous day (or not) and having seen a red wine test, I decided to do a beer test.

Testing materials - 500 ml bottle of Hatherwood "The Green Gecko" from Lidl. Alcohol 5% by volume. Nicely hoppy. Numnumnumnumnum......

BG immediately before test 5.6 mmol/L
BG 30 minutes after first mouthful (2/3 bottle gone by then) 5.4 mmol/L
BG 2 hours after test 6.3 mmol/L

So my BG dipped then went up slightly; however it seems to have stayed in the non-diabetic range for 2 hours after eating. I would have to test over a longer period to see if my BG was still above 6 a couple of hours later but scheduling this might be a problem. I was in trouble for delaying the evening meal as it was.

So what is this liquid toast thing?
I must remember to test with a couple of slices of toast at some point but don't want to knock myself out of ketosis at the moment.

Oh, and the methodology for post prandial testing says 30 minutes after the first mouthful then 2 hours. Not sure quite how that works with a relaxed social meal spread over 2 hours.

To do a proper comparison, you would have to know how many grams of carbohydrate were in your bottle of beer, then eat exactly the same number of grams of carbs in your toast.

Also, you would need to drink the whole bottle of beer in the same time that took you to eat the toast... spreading the beer out over 45 minutes or so will have a huge reduction in the overall blood glucose impact. This is why glucose tolerance tests require that we drink the Lucozade in 3 minutes.

Although... I have no idea how the two different foods vary in digestion time... so that would be another variable.

And then there are all the different beers; lager, bitter, stout...

The test lacked a certain amount of scientific rigour, but more than made up for this with participation pleasure.

It did have at least as much validity as the blanket "as many carbs as two slices of toast", I think.

Although random checking suggest perhaps 8g of carbs per slice of commercial wholemeal bread so it may not be that far out. Again another source suggests around 15g of carbs per large white slice so 30 g in total.

One glass of beer, often leads to another.
Much the same with slices of toast, or bread around a sandwich filling.

all I know is if I have a beer I wake up with considerably higher BS than when I don't

I was beginning to think this, but testing so far hasn't proved it.

Sometimes I go lower when I had a beer the day before.
