An effort by sixteen companies took 6.4 trillion calories out of food products in the U.S. between 2007 and 2012. The Robert Wood Johnson Foundation (or, RWJF) funded the study, which found that the participating companies had caloric sales totaling 60.4 trillion in 2007. By 2012, it was 57 trillion calories. This represents 78 fewer calories per person.
The goal to cut calories from food products began in 2009. That year, 40 nation-wide food retailers, non-profits, trade organizations, and food and beverage manufacturers collaborated to form the Healthy Weight Commitment Foundation (or, HWCF). Working together through HWCF, the organizations and companies aimed at reducing the rate of obesity and childhood obesity by 2015.
In 2010, the calorie-reduction pledge was announced, and sixteen companies signed on. Originally, the sixteen sought to cut a total of 1 trillion calories by 2012 and 1.5 trillion by 2015. Products by the companies accounted for 36 percent of the calories in packaged foods and drinks sold in the U.S. in 2007, according to RWJF. In order to reduce calories, the manufacturers planned on decreasing portion sizes, developing new, lower-calorie options and lowering the caloric count on existing products.
