We surveyed 7318 customers from 275 randomly selected restaurants of 11 fast food chains. Participants purchased a mean of 827 calories, with 34% purchasing 1000 calories or more. Unlike other chains, Subway posted calorie information at point of purchase and its patrons more often reported seeing calorie information than patrons of other chains (32% vs 4%; P < .001); Subway patrons who saw calorie information purchased 52 fewer calories than did other Subway patrons (P < .01). Fast-food chains should display calorie information prominently at point of purchase, where it can be seen and used to inform purchases.
