In Reply Does what you watch on television (TV) determine how much you eat? In our study reported in the September issue of JAMA Internal Medicine,1 94 participants were randomly assigned to snack while watching different TV content. Those assigned to watch a fast-paced action movie (The Island) ate 65% more calories than those assigned to watch a relatively slow-paced interview show (The Charlie Rose Show) (354 vs 215 cal).1 The study contended that the pacing of shows—operationalized by camera cuts and sound fluctuations—helped drive food intake.
