Researchers have discovered that the brain has a "mealtime clock" and suggest a short fast before air travel to reduce the grogginess associated with jet lag.

Though daylight is the main influence on the body's rhythms, the mealtime clock takes over when there's no grub available. By not eating, you can actually set your internal clock to match up with a destination.

One of the scientists involved explained the findings this way: "A single cycle of starvation followed by re-feeding turns on the clock, so that it effectively overrides [the circadian clock] and hijacks all of the circadian rhythms onto a new time zone that corresponds with food availability."

While this sounds good in theory, it will also mean no more overpriced airport fast food. And honestly, who wants to give up the opportunity to pay eight bucks for a Whopper?
