“据我所知,这属于首批不限制卡路里摄入的饮食方式长期试验,”塔夫茨大学弗里德曼营养科学与政策学院(Friedman School of Nutrition Science and Policy at Tufts University)院长达柳什·莫扎法里安(Dariush Mozaffarian)说。他没有参与这项新研究。“这表明,在可以想吃什么就吃什么的情况下,减少碳水化合物的摄入有助于减轻体重,而且还不需要关注卡路里。这一点很重要,因为与努力减少卡路里摄入相比,人们更容易改变饮食的种类。”
Diets low in carbohydrates and higher in fat and protein have been commonly used for weight loss since Dr. Robert Atkins popularized the approach in the 1970s. Among the longstanding criticisms is that these diets cause people to lose weight in the form of water instead of body fat, and that cholesterol and other heart disease risk factors climb because dieters invariably raise their intake of saturated fat by eating more meat and dairy.
自20世纪70年代,罗伯特·阿特金斯博士(Robert Atkins)开始推行低碳水化合物高脂高蛋白饮食以来,此类减肥方式就开始被广泛采用。一直有批评声认为,这种饮食习惯减去的是人体的水份,而不是脂肪,而且胆固醇等心脏疾病的风险因素也会随之攀升,因为人们食用了更多的肉类和奶制品,必然会增加饱和脂肪的摄入量。
Many nutritionists and health authorities have “actively advised against” low-carbohydrate diets, said the lead author of the new study, Dr. Lydia A. Bazzano of the Tulane University School of Public Health and Tropical Medicine. “It’s been thought that your saturated fat is, of course, going to increase, and then your cholesterol is going to go up,” she said. “And then bad things will happen in general.”
