Adherence
Repeated exposure to calorie labeling and value pricing modifications is likely required to influence food choices, as single exposure yields null results.
One-time exposure to menu changes is unlikely to change eating habits. Long-term exposure and education are likely necessary for behavior change.
ModerateQualifiesMEDIUM confidence
Studies in which participants are repeatedly exposed to these factors are needed since long term exposure may be required for behavior change.
