When teens eat at a fast-food restaurant, they typically consume 310 more calories than they do on average at home, according to a study published in the Archives of Pediatrics & Adolescent Medicine. They also tended to eat way more fat (25 percent more), 17 percent more sodium and 13 percent more sugar. Eating out wasn’t quite as unhealthy for kids under 11, but those younger children still consumed about 125 more calories at fast-food restaurants than when they ate at home. (Discovery)
