A whey-protein supplement increases fat loss and spares lean muscle in obese subjects: a randomized human clinical study

I believe you mean

"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.
