Increased
plasma PYY levels following supplementation with the functional fiber
PolyGlycopleX in healthy adults - Eur J Clin Nutr. 2010 Jul 28 -
"A variety
of dietary fibers have been shown to alter satiety hormone gene expression and
secretion. The objective of this study was to examine plasma satiety hormone
concentrations in healthy subjects consuming either PolyGlycopleX (PGX) or
control (skim milk powder) for 21 days ... Primary outcomes measured at three
visits (V1, V2 and V3) were plasma active glucagon-like peptide-1 (GLP-1) total
ghrelin, peptide YY (PYY) and insulin. Results: There was a significant effect
of visit for fasting PYY with control participants experiencing decreased PYY
levels over time while PGX prevented this decline. When stratified by body mass
index (BMI), PGX increased fasting PYY levels from week 1 to week 3 compared
with control in participants with BMI <23 kg/m(2). There was a significant
effect of visit for fasting ghrelin with levels decreasing in both PGX and
control groups over time. No differences were detected in fasting GLP-1 levels.
Although there was a 14% reduction in fasting insulin between V1 and V3 with PGX
this was not significantly different from control" - Note: I don't know
how they determine that a 14% reduction isn't significant. See

Exercise Suppresses Appetite By Affecting Appetite Hormones - Science

ghrelin"

What makes people fat, why diets don't work, and what triggers appetite? - Dr. Murray's Natural Facts, 3/17/04 -
"preliminary evidence indicates that
PGX™ has powerful
effects on reducing regulatory compounds that stimulate appetite like ghrellin while at the same time increasing the levels of regulatory compounds that block the appetite like PYY, CCK, and adiponectin. Further studies being conducted by Dr. Vuksan will likely show that PGX™ exerts powerful effects on these
appetite regulators" - See
