My wife and I try to eat healthy.  We're both active and have very busy schedules, so it's hard sometimes to avoid grabbing a quick bite of something unhealthy.  Now I have the reason why I have an insatiable craving...

A new study by Northwestern University reveals that junk food cravings increase when a person is lacking sleep. Researchers studied the cravings of 30 participants after they slept for only four hours. The participants with the least amount of sleep chose to eat higher calorie foods the following day. Scientists believe sleep-deprived people are more attracted to foods that are high in sugar, salt, and fat.

Professor Thorsten Kahnt says, "Our findings suggest that sleep deprivation makes our brain more susceptible to enticing food smells. It may be worth taking a detour to avoid your local doughnut shop the next time you catch a 6 a.m. flight."

So when my wife tells me not to eat those unhealthy snack foods, I get to tell her that she's right (which we should always do anyway guys) and that I'm going to take a nap!
