LOW GLYCEMIC DIET ON POST PARTUM WEIGHT LOSS

该方案的目的是确定强调食用低血糖碳水化合物的饮食是否有助于产妇产后体重和脂肪减少。20名孕妇将从我们正在进行的孕期锻炼研究中招募，并随机分为两组，低血糖饮食组和高血糖饮食组。受试者将在怀孕36周时开始适当的饮食，并持续到产后4个月。受试者的饮食中，15%-20%的卡路里来自蛋白质，55%-60%的卡路里来自碳水化合物，30%的卡路里来自脂肪。将通过每周至少收集一次24小时召回来评估饮食遵从性。每周监测体重；产后每月监测皮褶。

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.
