早餐时间和生理时钟类型与较低的BMI相关，但其对食欲的影响尚不清楚。我们研究了进餐时间和时间类型对食欲和食物奖励的影响。将44名成年人分为早发性（EC;晨昏问卷（MEQ）评分= 55 +/- 5）或晚发性（LC; MEQ评分= 40 +/- 6），并评估体重指数，习惯性能量摄入（EI;三天在线饮食记录）和三因素饮食问卷（TFEQ）的饮食行为特征。参与者在>= 3小时禁食后两次进入实验室，早期（上午8-10点）（下午4时至6时）在2 x 2设计中平衡测试会话。食欲等级和食物奖励（经验证的日间利兹食物偏好问卷）进行了测量，以响应标准化的测试餐。LC与较高的BMI相关（p = 0.01），但与EI或TFEQ无关。上午的复合食欲评分低于下午（M-Δ = -5（95% CI-10，-0.2）mm，p = 0.040）。在上午和EC中，对试验餐的饱腹感分别高于下午和LC（p
Early meal timing and chronotype are associated with lower BMI, but their impact on appetite is poorly understood. We examined the impact of meal timing and chronotype on appetite and food reward. Forty-four adults were divided into early (EC; Morningness-Eveningness Questionnaire (MEQ) score = 55 +/- 5) or late chronotype (LC; MEQ score = 40 +/- 6) and assessed for body mass index, habitual energy intake (EI; three-day online dietary record) and eating behavior traits from the Three-Factor Eating Questionnaire (TFEQ). Participants attended the laboratory after >= 3 h fast on two occasions for early (AM; 8-10 a.m.) and late (PM; 4-6 p.m.) counterbalanced testing sessions in a 2 x 2 design. Appetite ratings and food reward (validated diurnal Leeds Food Preference Questionnaire) were measured in response to a standardized test meal. LC was associated with higher BMI (p = 0.01), but not with EI or TFEQ. The composite appetite score was lower in AM than PM (M-Delta= -5 (95% CI -10, -0.2) mm, p = 0.040). Perceived test meal fillingness was higher in AM than PM and EC compared to LC (p
