最佳减肥法：低血糖指数饮食

路德维希博士说，低脂饮食对增加能量支出的效果最差。遵循这种饮食方案的研究对象还出现了甘油三酯（一种脂肪）水平上升，所谓的有益胆固醇的水平也有所降低。他说，我们应当避免严格控制任何一种主要营养素，而应该注意保证营养素的质量。

Dr. Ludwig said those on the low-carb diet had the biggest boost in total energy expenditure, burning about 300 calories more per day than those on the low-fat diet─about the same as an hour of moderate exercise. But that bump came at a cost: increases in cortisol, a stress hormone, and a measure of inflammation called CRP, which can raise the risk of developing heart disease and diabetes.

路德维希博士说，遵循低碳水化合物饮食的研究对象总能量支出的增幅最大，每日消耗量比低脂饮食者多300卡路里左右──这几乎等于一小时中等强度运动所消耗掉的能量。然而如此突出的效果是有代价的：应激素皮质醇水平升高，此外还导致一种名为C反应蛋白（CRP）的炎症标志物水平升高，它会增加罹患心脏病和糖尿病的风险。

Those on the low-glycemic-index diet burned about 150 calories a day more than those on the low-fat diet without any negative impacts on cholesterol levels or various hormones, making it the ideal diet, Dr. Ludwig said. The glycemic index measures the impact of carbohydrates on blood-sugar levels.
