Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The investigators hypothesize significant differences in the calorie amount of menu selections and food consumption across experimental conditions. The investigators anticipate that calorie amounts will be significantly higher in the no calorie information) compared to each of the other 3 conditions, and significantly lower in the Traffic Light conditions compared to calories only condition.
2\) Individuals in Condition 1 (no calorie information) will be significantly more likely to underestimate the calorie content of their meals compared to individuals in the intervention conditions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Menu - no nutrition information (control)
Participants were randomized to receive one of four menus that each contained different type of nutrition information. This condition included a "normal" menu with no nutrition information.
No interventions assigned to this group
Calorie labels
Participants were randomized to receive one of four menus that each contained different type of nutrition information. This condition included menus with the calorie amounts displayed.
Nutrition information on menus
Calorie Traffic Light
Participants were randomized to receive one of four menus that each contained different type of nutrition information. This condition included menus with calorie amounts in green/amber/red "traffic lights" to signify low/medium/high amounts.
Nutrition information on menus
Multi-Traffic Light
Participants were randomized to receive one of four menus that each contained different type of nutrition information. This condition included menus with calorie amounts as well as sodium, fat, and sugar amounts in green/amber/red "traffic lights" to signify low/medium/high amounts.
