胃旁路手术是严重肥胖患者的有效长期治疗方法。食欲、饮食摄入和食物偏好的变化都被认为有助于术后体重调节，然而，结果并不一致。本系统性综述的目的是在所使用的方法和结果的分析、解释和呈现的背景下，评价当前关于胃旁路手术后饮食摄入和食欲变化的文献。使用与“胃旁路手术”、“食欲”和“饮食摄入量”相关的术语系统检索了四个数据库，有49篇论文（n = 2384名胃旁路手术后的患者）符合纳入条件。证据表明，术后6个月后，仅总体能量摄入减少和餐后饱腹感增加，而相对常量营养素摄入和餐前饥饿感保持不变。然而，现有数据受到方法、分析、表述和结果解释不一致的限制。特别是，依赖于通过主观方法收集的数据，而很少承认其局限性，例如误报食物摄入量。有必要进行进一步的工作，采用客观的测量食欲和饮食摄入胃旁路手术后，以确定这些机制如何可能有助于体重调节在较长的时间。
Gastric bypass surgery is an effective long‐term treatment for individuals with severe obesity. Changes in appetite, dietary intake, and food preferences have all been postulated to contribute to postoperative body weight regulation, however, findings are inconsistent. The aim of this systematic review was to evaluate the current literature on changes in dietary intake and appetite following gastric bypass surgery, in the context of the methodology used and the analysis, interpretation, and presentation of results. Four databases were systematically searched with terms related to “gastric bypass surgery,” “appetite,” and “dietary intake,” and 49 papers (n = 2384 patients after gastric bypass) were eligible for inclusion. The evidence indicated that only a reduction in overall energy intake and an increase in postprandial satiety are maintained beyond 6‐month post‐surgery, whereas relative macronutrient intake and premeal hunger remain unchanged. However, available data were limited by inconsistencies in the methods, analysis, presentation, and interpretation of results. In particular, there was a reliance on data collected by subjective methods with minimal acknowledgment of the limitations, such as misreporting of food intake. There is a need for further work employing objective measurement of appetite and dietary intake following gastric bypass surgery to determine how these mechanisms may contribute to weight regulation in the longer term.
