Eating when you are hungry ensures that you don’t overeat later on in the day, Bonci says. And as for the type of food? According to Bonci, breakfast doesn’t necessarily have to be the traditional American meal of cereal, eggs, or pancakes. In fact, she says, in many Asian cultures, there isn’t really a specified “breakfast food.” People simply eat a varied diet regardless of the mealtime or type. “If you want leftover pepperoni pizza, that’s perfectly acceptable,” she says—though she adds that it’s also important to change it up and eat a balanced diet.
