Researchers are serving up more explanations as to why two recent reports on the effectiveness of the city’s ground-breaking calorie labeling law appear to contradict one another. The researchers told the Times that differences in focus and size might clarify the discrepancies.

An assistant commissioner in the city’s Department of Health and Mental Hygiene added, “Dietary changes come slowly. We were not expecting to see miracles.
