Isn’t that a really fascinating mechanism? All along I was thinking of fiber more from just an energy density perspective (as in my video Eating More to Weigh Less http://nutritionfacts.org/video/eating-more-to-weigh-less/), but the appetite-suppressing hormones are a whole new frontier. That underscores the urgency of the fact that 96% of Americans don’t even reach the recommended minimum intake of fiber (see my video Do Vegetarians Get Enough Protein? http://nutritionfacts.org/video/do-vegetarians-get-enough-protein/).
