Countries worldwide have committed to a zero increase in obesity by 2025. To meet this commitment, governments are encouraged to promote healthy behaviours and reshape obesogenic environments through a variety of population-wide policies.
The implementation of front-of-pack (FOP)nutrition labelling schemes is one such measure. Globally, six countries have mandatory FOP labelling schemes in place.
While other reviews investigated the effectiveness of FOP labels for preventing obesity, including which formats are likely to be more successful, the current one assessed the cost and cost-effectiveness, equity and acceptability of FOP nutrition labelling policies.
