  Background
  
  Energy intake is a key determinant of weight.
  
  Objective
  
  Our objective was to examine trends in energy intake in adults in the United States from 1971–1975 to 2009–2010.
  
  Design
  
  The study was a trend analysis of 9 national surveys in the United States that included data from 63,761 adults aged 20–74 y.
  
  Results
  
  Adjusted mean energy intake increased from 1955 kcal/d during 1971–1975 to 2269 kcal/d during 2003–2004 and then declined to 2195 kcal/d during 2009–2010 (P-linear trend < 0.001, P-nonlinear trend < 0.001). During the period from 1999–2000 to 2009–2010, no significant linear trend in energy intake was observed (P = 0.058), but a significant nonlinear trend was noted (P = 0.042), indicating a downward trend in energy intake. Significant decreases in energy intake from 1999–2000 to 2009–2010 were noted for participants aged 20–39 y, men, women, and participants with a BMI (in kg/m2) of 18.5 to <25 and ≥30.
  
  Conclusion
  
  After decades of increases, mean energy intake has decreased significantly since 2003–2004.
