So?....Where’s the link to that study?
Cephalic phase sweetener effect on insulin release is similar to the effects of the taste of
fat in the mouth, but without swallowing the fat, that results in an increase in serum triacylglycerol.
The idea with the effects on insulin release is that the sweet taste on the tongue stimulates insulin release. If someone's blood sugar is already low followed by a stimulation of insulin release, it will be decreased even more. The drop appears to the body to be indicative of a need for a lot more food energy than is really needed, resulting in a sooner than normal and/or greater than normal level of hunger. Given genetic variability, it may be that some people are much more susceptible to this than others.
