PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

"Whey proteins also modulate several hormones that influence body
composition. Short term acute studies with whey proteins corroborate
the body composition changes seen with longer term feeding studies.
Whey protein isolate (75 grams per dose) was evaluated [12] for its
impact on obesity-related hormones in an acute (5 hour) protein
ingestion in overweight and obese women with polycystic ovary syndrome
(PCOS). The acute hormonal response showed significantly lower
hyperinsulinemia (less lipogenesis), lower cortisol levels (lean
muscle preservation) and increased ghrelin release (satiety
enhancement)."

The last line in the paragraph is inaccurate, as even the most amateur
nutrition student can tell you. Increased ghrelin release stimulates
appetite, not satiety. Satiety is enhanced by the release of the
hormone known as leptin, and is released after a meal to let the body
know it's had enough. A quick reference to research cited earlier
in the paragraph also indicates the link between ghrelin and hunger,
and suggests that the acute hormonal response to the whey supplement
resulted in the suppression of ghrelin, not the increased release of
the hormone.

In addition to this inaccurate review of the published material, in
the methods section of the same article, diet "dairies" are discussed,
rather than diaries. Thought you'd like to correct the simple typo.
