Nutritional authorities now allege that even skipping one single meal will have dire health consequences. You must always eat breakfast. You must snack constantly, all day long. You should eat a bedtime snack. You must never, ever miss a meal. These messages are everywhere—on television, in the newspaper, in books. Hearing them over and over again creates the illusion that they are absolutely true and scientifically proven beyond a doubt. The truth is exactly the opposite. There is no correlation whatsoever between constant eating and good health.
