http://www.nutritionandmetabolism.com/content/5/1/8/comments The latest comments on the article 'A whey-protein supplement increases fat loss and spares lean muscle in obese subjects: a randomized human clinical study' 2011-01-26T12:00:58Z http://www.nutritionandmetabolism.com/content/5/1/8/comments#462692 <p>(from page 2) <br/>"Whey proteins also modulate several hormones that influence body <br/>composition. Short term acute studies with whey proteins corroborate <br/>the body composition changes seen with longer term feeding studies. <br/>Whey protein isolate (75 grams per dose) was evaluated [12] for its <br/>impact on obesity-related hormones in an acute (5 hour) protein <br/>ingestion in overweight and obese women with polycystic ovary syndrome <br/>(PCOS). The acute hormonal response showed significantly lower <br/>hyperinsulinemia (less lipogenesis), lower cortisol levels (lean <br/>muscle preservation) and increased ghrelin release (satiety <br/>enhancement)." <br/> <br/>The last line in the paragraph is inaccurate, as even the most amateur <br/>nutrition student can tell you. Increased ghrelin release stimulates <br/>appetite, not satiety. Satiety is enhanced by the release of the <br/>hormone known as leptin, and is released after a meal to let the body <br/>know it's had enough. A quick reference to research cited earlier <br/>in the paragraph also indicates the link between ghrelin and hunger, <br/>and suggests that the acute hormonal response to the whey supplement <br/>resulted in the suppression of ghrelin, not the increased release of <br/>the hormone. <br/> <br/>In addition to this inaccurate review of the published material, in <br/>the methods section of the same article, diet "dairies" are discussed, <br/>rather than diaries. Thought you'd like to correct the simple typo.</p> Laura Buti 2011-01-26T12:00:58Z http://www.nutritionandmetabolism.com/content/5/1/8 Frestedt et al.
