Study: Junk Food Doesn’t Only Make You Fat, It Makes You Lazy
According to a recent study by researchers at the University of California Los Angeles, a diet rich in processed food and fat leads not only to excess weight but also to less motivation. Researchers found that rats on a junk food diet were significantly fatter than rats on a healthy diet. But the rats with the unhealthy diet also were less active and mentally slower. "Our data suggest that diet-induced obesity is a cause, rather than an effect, of laziness. Either the highly processed diet causes fatigue or the diet causes obesity, which causes fatigue," says lead researcher Aaron Blaisdell.
