Daniel Engber deflates the pro-breakfast hype:
A study published last week in the American Journal of Clinical Nutrition starts with this simple fact—that in spite of all these association studies, no one knows exactly what skipping breakfast might be doing to our bodies. The study goes on to make a disturbing claim: Scholars in this field of inquiry—breakfast science—have been fudging facts and misinterpreting the science. The literature shows signs of research bias.
That doesn’t mean any of the studies described above is fraudulent or dubious. There certainly is a link between skipping meals and getting fat, but Andrew Brown, a nutritionist at the University of Alabama at Birmingham and lead author of the new critique, points out that large surveys of people’s diets and their health are at most suggestive. Lining up several dozen of them in a row doesn’t add much more value to their claims. It could be that my yuppie morning ritual really keeps my BMI in check, perhaps by changing my metabolism or helping to control my appetite. But it’s also possible that my breakfast habits do nothing for me on their own, and that they only correspond to some deeper determinants of health.
