Most people think breakfast is incredibly important; ask five people to the "most important meal" and three or four will say breakfast.

And science seems to back that up. Studies show that kids who eat breakfast tend to perform better in school. Even the NIH says breakfast "has been suggested to positively affect learning in children in terms of behavior, cognitive, and school performance." Other studies show that men who skip breakfast have a greater risk of heart disease than those who eat breakfast. And plenty of studies show that skipping breakfast correlates with obesity.

My mom was definitely a believer. She made sure we ate breakfast every morning. To her, us missing breakfast would have been like us forgetting to get dressed before we left the house. It just wasn't done.

So I've eaten breakfast my whole life. I usually eat within ten minutes of waking up. (I eat about six small meals a day, which also means that at any point in the day I'm about thirty minutes away from feeling hungry.)

Me, I'm all-in on the importance of breakfast.

Yet my wife rarely eats breakfast. Sometimes she doesn't eat until lunchtime and suffers no ill effects: she's one of the smartest, most productive people I know, and she's trim and fit and, well, let's just say I'm a lucky guy. And as for heart disease? I've eaten breakfast my whole life... and I've had a heart attack.

Granted my wife and I comprise just two data points, but our "findings" may not be a lot less accurate than much of the research.

The heart disease study sounds scary but ultimately only shows that heart disease and skipping breakfast are correlated, not causal. It's a little like the old saying about churches: cities with more churches tend to have more alcoholics (or NBA fans or cat lovers or really anything.)

While that sounds like churches lead to alcoholism, the simpler explanation is that cities with more churches tend to have greater populations, meaning the number of people in any sub-set will also be greater. The number of churches and the number of alcoholics correlates, but is not causal.

The same is somewhat true for the finding that kids who eat breakfast perform better in school. While a hungry child is less likely to be able to focus, most of the research focuses on kids who are part of school breakfast programs, which means the majority of those kids come from underprivileged backgrounds and may not be getting enough to eat in general.

Having breakfast at school makes a difference for children who are chronically hungry, helping them focus after they had a decent meal. That meal just happens to be breakfast.

And as for the relationship between skipping breakfast and obesity? People smarter than me have found major flaws in the related research.

So what does all this mean?

Sometimes research is great. It's hard to argue that smoking isn't bad for you. It's hard to argue that sitting for long periods of time isn't bad for you.

Other times research is interesting but shouldn't necessarily affect how you live your life. If you don't eat breakfast and aren't obese, why change your routine? If you don't eat breakfast but hit the professional ground running hard each morning, why change your routine? If your cholesterol levels are peachy and your blood pressure is fine and your overall health is good and you don't eat breakfast, why change your routine?

If what you're doing is working for you, keep doing it.

And if it's not, make smart changes. Like all of us, you know the basics of how to eat healthy and get fitter. You know the right things to do; you're just not doing those things.

So just start doing more of what you already know is good for you.

Yes, it really is that easy -- and, of course, it is that hard.

That may include eating breakfast. Or it may not.

What matters is what works for you.
