This study discusses how increased screen time leads to overeating and obesity. The study included two different schools and reducing screen time for one. After 7 months of reduced screen time, those children had slower weight gain than the children that had no screen time reduction. The children who have more screen time tend to eat less nutrient-dense food and have a higher calorie intake. These authors all have their PhD.
