Dimming the lights and lowering the volume at quickservice eateries can result in patrons consuming fewer calories, according to a new study. Researchers retrofitted a Hardee's with plants, indirect lights, instrumental music and other trappings of a more upscale eatery, and found patrons lingered longer but ate less. "These results suggest that a more relaxed environment increases satisfaction and decreases consumption," said study co-author Brian Wansink.
