Kelly Brownell of Yale's Rudd Center for Food Policy and Obesity and Jeffrey Koplan of Emory University questioned why the Grocery Manufacturers Association and Food Marketing Institute would unveil the system when the government already had asked the Institute of Medicine to issue front-of-package nutrition-labeling recommendations, suggesting that the industry motive was to "lock in a system that would change food choices as little as possible."
The number of daily meals and snacks consumed by U.S. adults increased from 3.8 in 1977 to 4.8 in 2006, according to researchers at the University of North Carolina.

The study was published in the journal Obesity Reviews.
