Adherence
Modified calorie labels, such as traffic light systems or daily calorie recommendations, can encourage lower-calorie purchases, potentially more effectively than calorie labels alone in some contexts.
If you are designing a menu or choosing food, look for modified labels like traffic lights or daily calorie recommendations. They can help you make lower-calorie choices, especially when combined with plain calorie numbers.
ModerateSupportsMEDIUM confidence
The limited data on modified calorie labels find that such labels can encourage lower-calorie purchases but may not differ in effects relative to calorie labels alone.
Why this rating
Limited data, but shows promise in specific studies.
