Everyone was followed for a year (which is an eternity for a nutrition study). Everyone was encouraged to maximize vegetable intake; to minimize added sugar, refined flour and trans fat intake; and to focus on whole foods that were minimally processed. The subjects were also encouraged to cook at home as much as possible.

每个实验对象都被追踪了一年(这对营养学研究来说这是很长一段时间)。所有人都被鼓励尽量多摄入蔬菜，少摄入添加糖、精制面粉和反式脂肪酸，并重点食用简单加工的全天然食物。实验对象还被鼓励尽可能在家做饭。

All the participants took a glucose tolerance test as a measurement of insulin sensitivity. Some believe that insulin resistance or sensitivity may affect not only how people respond to diets, but also how well they adhere to them. The participants were also genotyped, because some believe that certain genes will make people more sensitive to carbohydrates or fat with respect to weight gain. About 40 Data were gathered at the beginning of the study, at six months and at one year. At three unannounced times, researchers checked on patients to see how closely they were sticking to the instructions.

所有参与者都接受了葡萄糖耐量测试，以衡量他们的胰岛素敏感性。一些人认为，胰岛素抵抗或敏感性不仅会影响人们对饮食方式的反应，还会影响他们对饮食方式的坚持情况。参与者还接受了基因分型，因为一些人认为，就体重增加而言，某些基因会使人们对碳水化合物或脂肪更敏感。大约40%的参与者属于低脂基因型，30%属于低碳水化合物基因型。

percent of participants had a low-fat genotype, and 30 percent had a low-carbohydrate genotype.

研究过程中收集了三次数据，分别是研究开始、六个月和一年时。研究人员分三次在不事先通知的情况下查看患者严格遵守指导的情况。
