After the biggest meal of the year, Americans might reflect on the fate of those moldering Thanksgiving leftovers. Here's a data point to start with: At least one-third of the United States food supply goes to waste, according to researchers at the National Institutes of Health. Usually, waste is estimated through consumer interviews or garbage inspections. Physiologist Kevin Hall and mathematician Carson Chow of the National Institute of Diabetes and Digestive and Kidney Diseases tried another approach: modeling metabolism. They estimated how much American adults eat per capita (2300 calories) from their average weight (80 kg), then compared the figure with the food available for U.S. consumers, as reported to the Food and Agriculture Organization of the United Nations.
