Dimming the Lights Cuts the Calories
Turn down the lights and turn up the … healthy eating? A study found that when a fast-food restaurant softened the music and dimmed the lights, customers consumed 18 percent fewer calories, enjoyed their food more, and spent just as much money on the meal, so everybody won. People ordered the same menu items regardless of the ambience, but they ate more under blazing lights and blaring music. The relaxed mood may help diners focus on and enjoy their meals, perhaps providing a subtle prompt to eat slowly or to notice when a tummy becomes full.
