LOW GLYCEMIC DIET ON POST PARTUM WEIGHT LOSS

本方案的目的是确定强调低糖碳水化合物消耗的饮食是否有助于产妇产后体重和脂肪的减少。我们将从正在进行的孕期运动研究中招募20名孕妇，随机分为低血糖饮食组和高血糖饮食组。受试者将在妊娠36周开始适当的饮食，并持续到产后4个月。受试者的饮食中蛋白质占热量的15-20%，碳水化合物占热量的55-60%，脂肪占热量的30%以下。将通过每周收集至少一次24小时召回来评估饮食依从性。每周监测体重；产后将每月监测皮肤褶皱情况。

The purpose of this protocol is to determine if a diet emphasizing consumption of low glycemic carbohydrates facilitates maternal post-partum weight and fat loss. Twenty pregnant women will be recruited from our on-going exercise in pregnancy study and randomized into one of two diet groups, low glycemic and high glycemic. Subjects will start the appropriate diet at 36 weeks gestation and continue until four months postpartum. Subjects will eat a diet containing 15-20% of their calories from protein, 55-60% of the calories as carbohydrates, and <30% of the calories from fat. Diet compliance will be assessed by collecting at least one 24-hour recall per week. Weight will be monitored weekly; skinfolds will be monitored monthly in the post-partum period.
