一项研究指出，节食会让你感觉悲惨，而且会增大你患抑郁症的风险。研究人员发现，那些成功瘦身的人感觉悲伤、寂寞和消沉的几率比体重保持不变或变胖的人大一倍。 广告上总是宣扬节食者变瘦后人生会大有改观。然而在成功瘦身后，节食者却发现除了体重减轻外，生活并没有变好。 而且，节食本身就是很困难的过程，不但需要相当大的意志力，而且为了减肥许多节食者不再下馆子吃大餐，从而失去了人生的一大乐趣，这也导致节食者情绪低落。 It's easy to assume that when you finally lose those excess pounds, life will change for the better. But dieting can in fact make you miserable and more at risk of depression, a study claims. Researchers found that losing weight didn’t make people happy. Instead, those who successfully slimmed down were almost twice as likely to feel sad, lonely and lethargic than those who stayed the same weight or got fatter. The large-scale research, at University College London, found that the advertising industry tells dieters their lives will be transformed when they are thinner. They then feel disappointed when they discover little has changed other than their weight. In addition, dieting itself can be difficult, which in turn can cause people to feel down. The findings come from a study of almost 2,000 overweight and obese men and women aged 50 and over. |
