Adherence
Residing in areas with higher fast food restaurant access is associated with higher body mass index (BMI) in adults, though this association is inconsistent and not observed in children.
If you live in an area saturated with fast food, recognize that this environment makes unhealthy eating more convenient and likely. You can mitigate this by planning meals ahead, keeping healthy snacks accessible, or seeking out full-service restaurants with healthier options, understanding that your physical surroundings exert a subtle but real pressure on your dietary habits.
Six adult studies found higher body mass index was associated with living in areas with increased exposure to fast food; four studies, however, did not find associations. In children, only one of five studies found an association between BMI and the fast food environment.
Why this rating
The review synthesizes 40 studies, mostly cross-sectional, with mixed results and potential confounding (e.g., transportation access, SES).
