Time Spent Eating and Its Implications for Americans' Energy Balance

The upward trend in Americans' weight has precipitated research aimed at identifying its underlying causes. In this paper we examine trends in Americans' time spent eating in an attempt to gain a better understanding of Americans' changing eating habits and their predictors. Data used in the analyses come from four national time use surveys conducted between 1975 and 2007. We find that Americans' total eating time has risen over the past 30 years largely because of increases in secondary eating time. Multivariate analyses reveal that shifts over time in wage rates, food prices, household income, and racial/ethnic composition may be contributing to Americans' changing eating patterns.
