The myth that eating late at night is popular because it is widespread, this makes people believe it. With influences such as Oprah herself advising against late night snacks, we're influenced. The myth is false because overall a calorie is a calorie. People believe that we don't lose or burn calories as we sleep, but this is false. We do lose calories.
Responsible actions to take whilst eating late at night is to avoid it, or best eat a calorie-controlled snack. Research has shown that late-night eaters tend to make poor food choices and aim for the yummy (but unhealthy) stuff.
Hope this helped!
