摘要

Abstract Research suggests that individuals with high liking for sweets are at increased risk for binge eating, which has been minimally investigated in individuals with binge-eating disorder (BED). Forty-one adults (85% female, 83% white) with binge eating concerns completed a sweet taste test and measures of eating disorder behaviors and food cravings. A subset of participants with BED completed an oral glucose tolerance test (OGTT; N =21) and a 24-hour dietary recall ( N =26). Regression models were used to compare highest sweet preferers (HSP [ N =18]) to other sweet preferers (OSP [ N =23]) and were used to assess associations between sweet taste preference and outcome variables. Effect sizes ( ηp 2 ) for differences between HSP and OSP ranged from small (≤0.01) to large (≥0.24); group differences were statistically nonsignificant except for 24-hour caloric intake ( ηp 2 =0.16, p =0.04), protein intake ( ηp 2 =0.16, p =0.04), and insulin sensitivity index ( ηp 2 =0.24, p =0.04), which were higher in HSP, and postprandial insulin, which was smaller in HSP ( ηp 2 =0.27, p =0.03). Continuous analyses replicated postprandial insulin response. Compared with OSP, HSP reported numerically higher binge-eating frequency ( ηp 2 =0.04), over-eating frequency ( ηp 2 =0.06), and carbohydrate intake ( ηp 2 =0.14), and they exhibited numerically smaller postprandial glucose AUC ( ηp 2 =0.16). Sweet taste preference may have implications for glucose regulation, binge-eating frequency, and nutrient intake in BED. Highlights ? Sweet taste preference may be quite prevalent in individuals with BED. ? Highest Sweet Preferers have more binge-eating episodes than Other Sweet Preferers. ? Highest Sweet Preferers have smaller postprandial glucose and higher insulin sensitivity. ? Highest Sweet Preference may be a meaningful sub-phenotype of those with BED.
