Accepting everything you just said as fact, which it definitely is, do you know any more about the mechanism?

What I don't understand is: are you saying that the body says 'hang on here comes a meal - but it doesn't have any carbs in it so ill make some carbs from that protein thats been sent right now' causing a post-prandial increase in glucose as a direct result of the protein meal, even though there was no carb in the food

Or does it say:

'You know no carbs have come along that GI tract for a bit and I'm feeling hungry, ill burn a few left over amino acids to make some energy' ?

I know the second one happens after a while, although would expect it to happen whether I'd eaten some protein or not because a non-starving western person is likely to have some amino acids stores somewhere, often in the liver, that it can use to make some energy. In my head its called gluconeogenesis but I'm no biochemist and might have made that up.

But unless the first one happens, which it might well, ie the fact that protein has come along stimulates the body to get burning it for fuel right away when it wouldnt normally - I just don't understand why eating protein is going to affect the test....?

Sounds like both of what you are saying really 🙂
 
Mmmmm thanks guys. not as simple as one or the other....... Suppose I shouldn't be surprised there!

So ......We burn 20-40g protein per (normal?) day for energy and more muscular people / hungry people do it more.....

I'm on another site where a lot of people say they actually bolus extra for high protein, suddenly beginning to understand the problem if not the answer!
 
In non Ds eating protein is accompanied by a release of insulin and a compensatory release of glucose to stop levels falling.
(if you move on to the next page in the link that Adrienne gave it explains this)

Some years ago researchers tested different foods to find out how much insulin was released when various foods were eaten. They tested portions of food containing the same amount of calories and devised an insulin index. (like the glycemic index; same people) The results are interesting eg eggs caused a similar insulin release to All Bran (and similar resultant glucose increase)
.http://en.wikipedia.org/wiki/Insulin_index

The researchers then seemed to forget about the idea and went on to promote the glycemic index. More recently though they've gone back to it and did a small trial that showed insulin dosing using the normal insulin demand rather than just the carb content worked better for a lower carb meal than carb counting . Unfortunately the insulin index data base only has 120 foods at the moment.

Yep I have a friend who used to bolus for eggs if her boys with t1 ate them (even along with carbs). It did make a difference. Not sure if she does or not now, things tend to change with children. I never used to bolus for fruit with Jessica (except grapes and bananas) now we bolus pretty much everything x
