Physical activity maybe is the thing that should be focused on. Maybe it's something other than physical activity. Maybe you have sleep. Maybe people who sleep late, and they're not getting enough sleep, maybe someone who's not getting enough sleep, maybe that leads to obesity. And obviously, because they're not getting enough sleep, they wake up as late as possible and they have to run to the next appointment, or they have to run to school in the case of students. And maybe that's why they skip breakfast. So once again, if you find someone's obese, maybe the rule here isn't to force a breakfast down your throat.
