Eat Too Much, and There Goes the Food Clock

Old Clocks

As you sit there salivating over all the delectable foods of the holiday season, keep one thing in mind: over indulging upsets the food-entrainable oscillator, commonly known as the food clock, which keeps your metabolism functioning properly.  A new study by researchers at the University of California, San Francisco show how this clock helps your body get the maximum benefit from the foods you consume.

These researchers found that a protein called PKCγ is a major factor in resetting the food clock when our normal eating routine is subject to change. They discovered that mice who were fed only during their normal sleeping hours will alter their food clock and wake up and run around when they knew it’s mealtime. But mice who don’t have the PKCγ gene sleep right through their newly adjusted  feeding time. That’s because PKCγ binds to another molecule known as BMAL in order to stabilize it, which changes the clock in time. If there is no PKCy, the clock doesn’t shift.

When PKCy is present, the food clock can eventually be reset if an organism modifies existing eating patterns, overeats or eats at odd times.
