High-Fat and the Body Clock
New research suggests that a high-fat diet can muck up your body’s 24-hour clock. Robert Preidt of HealthDay News spills the beans:
There's more bad news about a high-fat diet -- it disrupts the body's 24-hour internal (circadian) clock, which regulates sleeping, waking, eating, as well as the daily rhythms of many metabolic functions, U.S. researchers say.Another reason to ditch that nasty cheeseburger!
A team from Northwestern University and Evanston Northwestern Healthcare (ENH) found that mice fed a high-fat diet gained weight and showed a sudden disruption in their circadian clock, eating extra calories when they should have been sleeping or resting.
The team also found that a high-fat diet caused changes in genes that encode the circadian clock in the brain and in peripheral tissues (such as fat), resulting in reduced expression of these genes.
