上述新研究论文的第一作者、杜兰大学公共卫生及热带疾病学院(Tulane University School of Public Health and Tropical Medicine)的莉迪娅·A·巴扎诺博士(Lydia A. Bazzano)表示,许多营养学专家和卫生部门都“大力反对”低碳水化合物的饮食方式。“他们总是认为,你的饱和脂肪摄入量肯定会增加,然后你的胆固醇就会升高,”她说。“接下来,通常会带来不良后果。”
The new study showed that was not the case.
这项新研究表明,事实并非如此。
By the end of the yearlong trial, people in the low-carbohydrate group had lost about eight pounds more on average than those in the low-fat group. They had significantly greater reductions in body fat than the low-fat group, and improvements in lean muscle mass — even though neither group changed their levels of physical activity.
在为期一年的试验结束时,低碳水化合物摄入小组的成员体重,比低脂肪小组平均多减了8磅左右(约合3.6公斤)。与后者相比,他们的体脂减少量明显更大,而且精瘦肌肉量也增加了——虽然两组受试人员均没有改变身体活动量。
While the low-fat group did lose weight, they appeared to lose more muscle than fat.
尽管低脂肪摄入小组的成员的确减轻了体重,但他们失去的肌肉似乎比脂肪更多。
“They actually lost lean muscle mass, which is a bad thing,” Dr. Mozaffarian said. “Your balance of lean mass versus fat mass is much more important than weight. And that’s a very important finding that shows why the low-carb, high-fat group did so metabolically well.”
