Few people in the United States have diets with proportions of complex carbohydrate as high and proportions of protein, fat, and sugar as low as proposed in the second edition of the Dietary Goals for the United States by the Senate Select Committee on Nutrition and Human Needs. Sample diets, including low-calorie diets for adults, were planned to meet the Recommended Dietary Allowances and the Dietary Goals. Two possible "first steps" in modifying diets to meet the Goals explored the use of: (a) Specified ranges rather than specific Goals and (b) some but not all of the Goals.
在美国，很少有人的饮食中复合碳水化合物的比例能像美国参议院营养与人类需求特别委员会发布的《美国膳食目标》第二版中建议的那样高，而蛋白质、脂肪和糖的比例能像该版建议的那样低。样本饮食，包括成人低热量饮食，旨在满足推荐膳食摄入量和膳食目标。为使饮食符合这些目标而对饮食进行调整的两个可能的“第一步”探讨了以下两种做法的使用：(a) 指定范围而非具体目标，以及(b) 部分而非全部目标。
