This systematic review and meta-analysis aimed to summarize the evidence on the associations of energy and macronutrient intakes (carbohydrates, fats, and proteins) with weight loss in adults after sleeve gastrectomy or gastric bypass and to determine whether these dietary characteristics of patients with suboptimal weight loss (SWL) or weight regain differ from those without these experiences.
PubMed, Scopus, and Web of Science were searched until December 2021. Twenty-three observational studies were included.
Studies on the association of postoperative energy and macronutrients and weight loss used diverse approaches. Pooled results showed that patients with SWL consumed more energy than those with acceptable weight loss. Weight regainers consumed more energy and carbohydrates and less protein than non-regainers.
Higher energy consumption is related to SWL and weight regain after surgery. Associations between macronutrients and weight outcome following bariatric surgery warrant further investigation.
本系统评价和荟萃分析旨在总结袖状胃切除术或胃旁路术后能量和宏量营养素（碳水化合物、脂肪和蛋白质）摄入与成年人减肥的关系，并确定术后体重减轻不理想（SWL）或体重反弹患者的这些饮食特征是否与无这些经历的患者有所不同。
检索了 PubMed、Scopus 和 Web of Science，截至 2021 年 12 月。共纳入 23 项观察性研究。
术后能量和宏量营养素与减肥关系的研究采用了不同的方法。汇总结果表明，SWL 患者的能量摄入高于可接受的减肥患者。体重反弹者的能量和碳水化合物摄入更多，而蛋白质摄入更少。
术后能量摄入较高与手术减肥效果不佳和体重反弹有关。肥胖症手术后宏量营养素与体重结局之间的关系需要进一步研究。
