I read a study about it a year or so ago, can't find it now. Of course that study might have been flawed, this notion can be a myth and we only scratched the surface of how our metabolism works.
We should be wary of claims based on various studies, no matter the side they are arguing for, as most studies are flawed. Especially in regards to nutrition and dieting, it's next to impossible to do these studies double-blind, or to monitor the daily routine of subjects, or to trust what they declare (most people lie about their diet).
It does make some sense. I also read about a study on a dog, being kept in a dark room and fed at regular hours. After some time, his saliva glands started generating saliva at feeding time, even though he had no noise, no smell, no eyesight, nothing to indicate that feeding time is coming. The autonomous nervous system can be trained to do things out of reflex. If external stimuli work on the pancreas, I don't know, but it does make some sense, so that's why the idea is gaining traction.
> Nitpicking, simple carbs can burn slower than complex ones. Eg some fruits vs white bread. Fruits will release fructose into your blood stream slowly due to fiber
Of course, what I wrote is an over-simplification. I was speaking about sweetened foods and beverages, most of which are lacking in fiber.
Also, white bread is dangerous, but it's not really the problem or maybe you could say that our usage of white flour in general is, but I think the effects of white bread are negligible.
Think of your acquaintances or even your family - how many of them consume at least a half a gallon of beverages sweetened with corn syrup daily? How many of them put two spoons of sugar in their coffee? How many eat cookies daily? If you look around, you'll discovered enormous amounts of sugar being consumed by people. And that was my point.
EDIT; RE: What you really want is to know the glycemic index (GI) of the food you're eating
The glycemic index is slightly inadequate. It provides a useful clue, but it was shown to be inadequate in regards to the insulin response.
For example, if you take a look at "beer" it is off the charts, but paradoxically maybe, beer was shown to not generate much of a response from the pancreas, as the GI would led you to believe. And this may be because beer can't be tested properly OR because the secretion of insulin may not be fully in response to the real glucose levels in the blood.
That's why we now also have the insulinemic index for example (and round and round we go :))
