Feeling sleepy? It could be something you ate, like a deliciously fatty piece of steak. The New York Times reports that researchers at the University of Adelaide have found a link between high fat diets and daytime sleepiness. Sad but true. The researchers studied 1,800 men, surveying them about what they ate and how sleepy they felt during the day. Ready? The envelope please…After adjusting for all kinds of things, the researchers found that compared with those in the lowest one-quarter for fat intake, those in the highest one-quarter were 78 percent more likely to suffer daytime sleepiness and almost three times as likely to have sleep apnea. The takeaway: for more energy, eat less fat.
