That is fascinating.
Somewhat inadvertantly, my experimentation kicked off again recently. I decided to do my own DIY version of Interminttent Fasting, but without risking the chance of any of those nasty hunger pangs. So I eat lunch and evening meal, and 'fast' for the other 16-17 hours a day. Except that I can eat fat during the 'fast'. Essentially, this means that breakfast is a cup of coffee with a good slug of double cream, which lasts me til lunch. And if I get peckish late evening, I have a mug of broth, again with cream.
I started it in the hope of triggering further weight loss - which has worked like a charm - after a 8 month plateau.
But the additional side effect is that my DP has definitely reduced. By an average of 0,5-1 mmol/l every morning.
I am delighted.
I will however have a sniff (
) at your 'cephalic pase insulin release' and see if it looks like a possibility. Although, I must admit that my first reaction on reading your suggestion was to question your sanity. When, in the history of the world, has a jelly baby been that close to a human nose and mouth and lived to tell the tale? (or set aside for sniffing the next morning?) I mean, REALITY CHECK, please!
Will let you know if I try it though.
