Restaurant menu calorie labeling was also projected
to be cost-saving (Exhibit 2), although on
average the uncertainty intervals were wide because
of the wide uncertainty interval around the
estimated per meal reduction in calories ordered
or purchased as a result of the intervention (see
Appendix A4).11 This uncertainty highlights the
need for ongoing monitoring of this policy when
it is implemented nationwide in 2016. Of note, a
study of restaurant menu calorie labeling in King
County, Washington, found that eighteen
months after implementation of menu calorie
labeling regulations, restaurants had reduced
their calorie content by 41 kilocalories per entrée,
29 a much larger effect than the reduction of
8 kilocalories per meal estimated in this study.
