Low-carbohydrate (LC) weight-reducing diets are popular choices for self-dieters. Eighteen adults (BMI >/= 25 kg/m(2)) were enrolled in this short-term longitudinal study to evaluate dietary intake and weight on their "usual" diets and LC diet. Subjects were instructed to follow the first two phases of the diet described in Dr. Atkins' New Diet Revolution (2 weeks each). Total daily intake of calories and nutrients were calculated from 3-day food diaries. Body weight was measured at the end of each 2-week diet session. All enrolled subjects completed the study (age = 39.8 +/- 8.1 years, BMI = 36.6 +/- 6.6 kg/m(2)). Mean caloric intakes were 1400 +/- 472 kcal/day (Induction diet) and 1558 +/- 490 kcal/day (Ongoing Weight Loss diet) both p </= 0.001 compared to "usual" (Baseline diet) 2481 +/- 723 kcal/day. Body weights were 107.4 +/- 24.2 kg, 103.6 +/- 23.0 kg and 102.1 +/- 22.6 kg at the conclusion of the Baseline, Induction, and Ongoing Weight Loss diets, respectively (both p </= 0.001). Decreases in daily caloric intake correlated with weight loss. Pearson correlation coefficients were, r = 0.64 (p </= 0.001) and r = 0.40 (p </= 0.001) for Induction and Ongoing Weight Loss diets versus "usual" diet. Caloric intake is decreased when otherwise healthy overweight and obese adults self-implement Atkins' Induction and Ongoing Weight Loss diets and significantly altered their dietary micronutrient intake. Weight loss can be explained by the self-selected lower caloric intake on The Atkins' Diet.
低碳水化合物（LC）减肥饮食是节食者的热门选择。本短期纵向研究纳入 18 名成年人（BMI≥25kg/m²），评估他们在“常规”饮食和 LC 饮食下的饮食摄入和体重。受试者遵循 Dr. Atkins 的新饮食革命（每阶段持续 2 周）中的前两个阶段进行饮食。通过 3 天的食物日记计算每日总热量和营养素摄入量。在每 2 周的饮食结束时测量体重。所有入组受试者均完成研究（年龄=39.8±8.1 岁，BMI=36.6±6.6kg/m²）。诱导饮食和持续减重饮食的平均热量摄入量分别为 1400±472kcal/天和 1558±490kcal/天（均 p≤0.001），与“常规”（基线饮食）2481±723kcal/天相比。基线、诱导和持续减重饮食结束时的体重分别为 107.4±24.2kg、103.6±23.0kg和 102.1±22.6kg（均 p≤0.001）。每日热量摄入的减少与体重减轻相关。诱导和持续减重饮食与“常规”饮食相比，Pearson 相关系数分别为 r=0.64（p≤0.001）和 r=0.40（p≤0.001）。当健康的超重和肥胖成年人自行实施 Atkins 的诱导和持续减重饮食并显著改变其饮食微量营养素摄入时，热量摄入会减少。体重减轻可以用 Atkins 饮食的自我选择较低热量摄入来解释。
