THURSDAY, May 22 (HealthDay News) -- New animal research suggests the body's biological clock, which regulates sleep cycles based on the rise and fall of the sun, can be overridden in extreme situations by an internal "food clock."
The finding is based on work with mice and has not yet been tested among humans. But early indications are that, when faced with starvation, the animals automatically adjust their wake-sleep schedule to adapt to the best time to access food.
