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.

每個實驗對象都被追蹤了一年(這對營養(yǎng)學(xué)研究來說這是很長一段時間)。所有人都被鼓勵盡量多攝入蔬菜，少攝入添加糖、精制面粉和反式脂肪酸，并重點食用簡單加工的全天然食物。實驗對象還被鼓勵盡可能在家做飯。

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.

所有參與者都接受了葡萄糖耐量測試，以衡量他們的胰島素敏感性。一些人認為，胰島素抵抗或敏感性不僅會影響人們對飲食方式的反應(yīng)，還會影響他們對飲食方式的堅持情況。參與者還接受了基因分型，因為一些人認為，就體重增加而言，某些基因會使人們對碳水化合物或脂肪更敏感。大約40%的參與者屬于低脂基因型，30%屬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.

研究過程中收集了三次數(shù)據(jù)，分別是研究開始、六個月和一年時。研究人員分三次在不事先通知的情況下查看患者嚴(yán)格遵守指導(dǎo)的情況。
