以前的研究表明,严格控制热量摄入而膳食成分不变,可导致体重降低,血浆中高密度脂蛋白(HDL)胆固醇的浓度明显升高。但近来的报告不赞成这种类型的膳食。相反,对体重适度超重的人普遍提倡应继续食用含热能较低的低饱和脂肪酸、低胆固醇膳食。还没有有关减肥膳食(伴有或不伴有体育锻炼)对血浆脂蛋白影响研究的报道。在斯坦福大学进行的一项试验,受试对象为体重适度超重者男女各132名,随机分成三组,一组为高能量组,其膳食成分按国家胆固醇教育计划中规定的标准配制;另一组为进食同一种膳食并加以强制性户外活动锻炼;对照组既不改变平时的饮食习惯,也不
Previous studies have shown that strict control of calorie intake without change in dietary composition can lead to weight loss and elevated plasma concentrations of high-density lipoprotein (HDL) cholesterol. However, recent reports do not favor this type of diet. On the contrary, moderate weight overweight people generally advocate the continued consumption of low-energy low-saturated fatty acids, low cholesterol diet. There are no reports of the effects of diet meals (with or without physical activity) on plasma lipoproteins. A study conducted at Stanford University, subjects were moderately overweight men and women 132 each 132 were randomly divided into three groups, one for the high-energy group, the dietary ingredients according to the provisions of the national cholesterol education program formulated; the other Group to eat the same diet and to exercise mandatory outdoor activities; control group neither change the usual diet, nor
