A pecan-enriched diet reduced postprandial appetite intensity and enhanced peptide YY secretion: A randomized control trial

What Was Tested

The paper reports a study of Peptide YY, published as a randomized controlled trial.

The purpose of this study was to examine the impact of a pecan-enriched diet on subjective, physiological, and direct measures of appetite in older adults.

Subjective appetite was measured using visual analog scale (VAS), and blood was collected to assess changes in physiological appetite before and every 30 min for 4 h following a high-fat meal.

Who Took Part

The age groups tagged for this paper are older adults.

VAS assessments continued hourly for the next 7 h and EI ("at-home") was self-reported.

How the Study Was Run

The design is described as randomized.

The participants were allocated by chance, so the Peptide YY group and the comparison group should start out alike.

At pre- (V1) and post-diet (V2) visits body weight (BW) and body fat percentage (BF) were assessed and actual change in these outcomes for pecan were compared to theoretical changes if pecans were consumed without compensation.

Energy intake (EI) at a buffet meal was then assessed in the laboratory ("in-lab").

What Was Measured

The subject headings attached to it are Appetite, Peptide YY, Carya, Diet and Fasting.

The authors tagged it with the keywords Cholecystokinin, Energy intake, Ghrelin, Hunger, Satiety and Tree nuts.
