I just came across this very interesting bit of information again and was wondering if you had any references for this effect on ghrelin and leptin of sweet receptor excitation. I’d very much like to dive deeper on this one.
I listen to Gabor and Raphi on the Break Nutrition podcast. They take an interesting study or two and explain them.
Podcasts number 3, 4, 6, 7, 8 are a good listen if you want an in-depth explanation of gut incretins and how they change hormones in response to foods. I may have misspoken about the leptin, but ghrelin and PYY are among those triggered in the digestive tract.
I think this is simply caused by insulin. If your blood glucose is high, insulin will be high (unless you are T1). When you have high insulin, the body cannot use bodyfat, so it keeps the feed me messaging going. If you have low blood glucose, (usually) you will have low insulin. Because of this, you can access bodyfat, and this switches the hunger hormones off.
Well, that’s my theory, anyway!
