简要总结
This study is a test of possible mechanisms by which calorie labels might lead people to increase calorie intake. The investigators hypothesize that calorie labels might increase calorie intake because 1) people infer that higher calorie foods are tastier, 2) calorie labels invoke thoughts of dieting, leading people to overconsume as a reaction, 3) people try to maximize calories consumed per dollar spent, and 4) calorie labels change one's goal motivation toward food, causing people to eat more.

结局指标
主要结局
Calories consumed
时间窗: At time of intervention (30 minutes)
The investigators will assess how many calories are consumed by participants by weighing the cereal provided before and after participants complete the taste test portion of the study. This will happen within 30 minutes of the intervention, which is an experimental manipulation of whether or not calorie labels are present.
