Is this promise the Holy Grail for dieters? Eat as much as you want and still keep on losing weight? Can you believe it - after all these years of gurus advocating abstinence in some form or another? Here are two secrets I can share with you. First, eat mainly low GI foods (LGI) and second, eat as much of them as you can in preference to high GI (HGI) foods. 这一承诺是节食者的梦啊！想吃多少就吃多少，同时还能减肥？你相信吗？--毕竟这些年来，大师们都在推崇各种各样的节制啊！我将与你分享这两个秘密。首先，主要吃血糖生成指数低的食物。其次，少吃血糖生成指数高的食物，尽可能的多吃血糖生成指数低的食物。 High GI foods are energy-dense and release their energy quickly so you feel hungrier sooner. Low GI foods are less energy-dense and release their energy slowly so you feel satisfied for longer. Leeds University researchers have found that bigger portions (rather than smaller) of "lower energy-dense" foods, such as vegetables, lean meat and rice, made participants feel less hungry, despite consuming fewer calories. 血糖生成指数高的食物能量密度高，释放能量快，所以你很快就会感到饥饿。血糖生成指数低的食物能量密度较低，释放能量缓慢，所以你会长时间保持饱腹感。利兹大学的研究员发现：大分量（而非少量）能量密度较低的食物，比如蔬菜、瘦肉和米饭，会让受试者不怎么感到饿，尽管摄入的卡路里量较低。 |
