  • Description: Background: Subjective appetite is a major driver of energy intake and can promote overconsumption, especially with high-fat (HF), palatable foods. Objective: To test the impact of a diet enriched with either cottonseed oil (CSO) or olive oil (OO) on postprandial appetite in adults with dyslipidemia. Methods: 42 adults (30-75y, BMI=27.5±4.71kg/m2) with high cholesterol were recruited for a single-blind, randomized trial. Subjects were randomized into either the CSO (n=21) or OO (n=21) group for an 8-week partial outpatient diet intervention with 2 test visits (preand post-diet). For the intervention, HF meals were provided by research personnel to account for ~60% of daily energy needs (~30% OO or CSO) while subjects consumed the remaining ~40% of energy needs with their normal free-living diet. At pre- and post-diet visits, participants underwent a high saturated fat meal challenge with 5h intermittent blood draws for ghrelin, cholecystokinin (CCK), Peptide YY (PYY), and visual analog scale (VAS) subjective appetite measures. Results: Postprandial ghrelin was suppressed more in the CSO group compared to the OO group from pre- to post-intervention (p=0.031). Postprandial CCK (p=0.018) and PYY (p=0.004) were higher at the post-diet visit in both groups. VAS questionnaires revealed similar improvements between groups in response to questions including suppressed hunger (incremental area under the curve (iAUC) CSO -26.6±21.7 to -46.5±32.3; OO -21.7±23.4 to -67.4±23.8 mm/5h, p=0.07), lower prospective consumption (iAUC CSO -18.8±20.0 to -32.2±26.4; OO -28.3±22.2 to post:-86.4±25.3 mm/5h, p=0.046), and lower composite appetite score (iAUC CSO -33.2±20.7 to48.9±27.1; OO -43.4±16.5 to -82.4±21.4 mm/5h, p=0.039) from pre- to post-diet, respectively. Conclusions: The greater suppression of ghrelin with CSO, and similar suppression of subjective ratings of appetite, CCK, and PYY, suggest that CSO may be slightly better than OO diet enrichment on appetite.
