This pilot trial investigated the feasibility and acceptability of reducing portion sizes in worksite cafeterias, estimated the impact on energy purchased.

Nine worksites in England were recruited to reduce by at least 10% the portion sizes of foods available in their cafeterias from targeted categories (main meals, sides, desserts, cakes). 

The results suggest that reducing portion sizes could be effective in reducing energy purchased and consumed from targeted food categories, and merits investigation in a larger trial.
