REM sleep time in a 12 hr period was found to predict accurately food intake in the subsequent 12 hr period in undisturbed cats fed ad lib. In all but one of the cats, the correlation between REM sleep and subsequent food intake was negative. REM sleep was a better predictor of food intake than either waking, slow wave sleep or previous food intake. Cats were then fed only during the 12 hr day period. It was found that REM sleep at night, during which no food was available, no longer predicted food intake.
