WHY HIGH PROTEIN, LOW CARB DIETS SEEM TO WORK BETTER
"Acyl and Total Ghrelin Are Suppressed Strongly by Ingested Proteins, Weakly by Lipids, and Biphasically by Carbohydrates."

Journal of Clinical Endocrinology & Metabolism, Jan. 15, 2008
by Dr. Karen Foster-Schubert, et al.


Context Ghrelin is an orexigenic hormone that can increase body weight. Its circulating levels rise before meals and are suppressed following food ingestion. Understanding the effects of specific types of ingested macronutrients on ghrelin regulation could facilitate design of weight-reducing diets. Objective We sought to understand how ingestion of carbohydrates, proteins, or lipids affect acyl (bioactive) and total ghrelin levels among human subjects, hypothesizing that lipids might suppress ghrelin levels less effectively than do either carbohydrates or proteins. Design Randomized, within-subjects cross-over study Setting University Clinical Research Center Participants 16 healthy human subjects Interventions Administration of isocaloric, isovolemic beverages composed primarily of carbohydrates, proteins, or lipids Main Outcome Measures Magnitude of postprandial suppression of total and acyl ghrelin levels (measured with a novel acyl-selective, two-site ELISA) Results All beverages suppressed plasma acyl and total ghrelin levels. A significant effect of macronutrient class on decremental area-under-the-curve for both acyl and total ghrelin was observed; the rank order for magnitude of suppression was protein > carbohydrate > lipid. Total ghrelin nadir levels were significantly lower following both carbohydrate and protein, compared to lipid beverages. In the first 3 postprandial hours, the rank order for acyl and total ghrelin suppression was carbohydrate > protein > lipid. In the subsequent 3 h, there was a marked rebound above preprandial values of acyl and total ghrelin after carbohydrate ingestion alone. Conclusions: These findings suggest possible mechanisms contributing to the effects of high-protein/low-carbohydrate diets to promote weight loss, and high-fat diets to promote weight gain (Abstract e-Published ahead of April, 2008 Journal Publication) ...
