流行的减肥计划通常有相互矛盾的建议，这使得很难确定最健康的减肥方法。我们的研究比较了流行减肥计划的饮食质量。饮食质量以替代健康饮食指数（AHEI）衡量，通过新葡萄糖革命、慧俪轻体、阿特金斯、南海滩、Zone、Ornish和2005年美国农业部食物指南金字塔（2005年食物指南金字塔）计划的出版媒体提供的样本菜单计算。决定哪些减肥计划最受欢迎的标准是它们在《纽约时报》畅销书排行榜上的地位。慧俪轻体（Weight Watchers）和2005年食物指南金字塔计划被包括在内，因为它们分别是最大的商业减肥计划和目前的政府推荐计划。方差分析用于比较不同减肥计划的营养信息。根据能量含量调整后的AHEI分数也进行了比较。在最高可能得分为70分的情况下，每个减肥计划的AHEI得分从最高到最低依次为：Ornish（得分64.6）、Weight Watchers的高碳水化合物（得分57.4）、New Glucose Revolution（得分57.2）、South Beach/Phase 2（得分50.7）、Zone（得分49.8）、2005 Food Guide Pyramid（得分48.7）、Weight Watchers的高蛋白（得分47.3）、Atkins/100克碳水化合物（得分46）、South Beach/Phase 3（得分45.6）和Atkins/45克碳水化合物（得分42.3）。不同减肥计划的饮食质量各不相同。经AHEI评估，Ornish、Weight Watchers的高碳水化合物和新葡萄糖革命减肥计划对心血管疾病的预防能力有所提高。
Popular weight-loss plans often have conflicting recommendations, which makes it difficult to determine the most healthful approach to weight loss. Our study compares the dietary quality of popular weight-loss plans' Dietary quality, measured by the Alternate Healthy Eating Index (AHEI), was calculated via sample menus provided in published media for the New Glucose Revolution, Weight Watchers, Atkins, South Beach, Zone, Ornish, and 2005 US Department of Agriculture Food Guide Pyramid (2005 Food Guide Pyramid) plans. The criterion for determining which weight-loss plans were the most popular was their status on the New York Times Bestseller list. Weight Watchers and the 2005 Food Guide Pyramid plan were included because they are the largest commercial weight-loss plan, and the current government recommendation, respectively. Analysis of variance was used to compare nutrient information among the weight-loss plans. The AHEI scores adjusted for energy content were also compared. Of a maximum possible score of 70, the AHEI scores for each weight-loss plan from the highest to the lowest plan were: Ornish (score 64.6), Weight Watchers high-carbohydrate (score 57.4), New Glucose Revolution (score 57.2), South Beach/Phase 2 (score 50.7), Zone (score 49.8), 2005 Food Guide Pyramid (score 48.7), Weight Watchers high-protein (score 47.3), Atkins/100-g carbohydrate (score 46), South Beach/Phase 3 (score 45.6), and Atkins/45-g carbohydrate (score 42.3). Dietary quality varied across popular weight-loss plans. Ornish, Weight Watchers high-carbohydrate, and New Glucose Revolution weight-loss plans have an increased capacity for cardiovascular disease prevention when assessed by the AHEI.
