Adding the part of the answer the thread has not reached. Most of what circulates confidently in this community traces back to one summary of one study, and the qualifier was dropped somewhere in the third retelling.
Adding the numbers, since they settle part of this. The mechanism that matters here is not stomach emptying, it is central.
