In fact, if Lady Gaga is trying to maintain her toned physique, lack of sleep might make it even tougher; a 2005 study found that sleeping fewer than seven hours a night corresponded with a greater risk of weight gain and obesity. And for every hour of lost sleep, that risk increased. And recent studies have found that both men and women consume significantly more calories when they're faced with fewer hours of sleep.
