I don’t think it’s a coincidence that celebrities do a good job of staying thin. Obviously they have the free time and resources to do it right. And for them, fitness has an enormous financial upside. But I think celebrities have another ace in the hole too, because their lives are fabulous in general. The happier you are in one area of your life, the less effort you’ll put into searching for happiness elsewhere. And that can translate into caring less about the taste quality of your meal.
