Dr. Aaron E. Carroll who in addition to writing for the NYTimes UpShot also has a great YouTube channel called  Healthcare Triage and blogs as The Incidental Economist writes on that old saw about breakfast being the most important meal of the day.

Sorry, There’s Nothing Magical About Breakfast

I don’t eat breakfast. It’s not that I dislike what’s offered. Given the choice of breakfast food or lunch food, I’d almost always choose eggs or waffles. It’s just that I’m not hungry at 7:30 a.m., when I leave for work. In fact, I’m rarely hungry until about lunchtime.
