So maybe if you're physically active, that leads to you being hungry in the morning. So you're more likely to eat breakfast. And obviously, being physically active also makes it so that you've burned calories, you have more muscle, so that you're not obese. So notice, if you view things this way, if you say physical activity is causing both of these, then all of a sudden you lose this connection between breakfast and obesity. Now you can't make the claim that somehow breakfast is the magic formula for someone to not be obese. So let's say that there is an obese person. Let's say this is the reality, that physical activity is causing both of these things.
