This systematic review evaluated the relationship between macronutrient intake and weight loss after bariatric surgery (BS). The MEDLINE/Pubmed, EMBASE, COCHRANE/CENTRAL, and SCOPUS databases were accessed in August 2021 to search for eligible articles: original publications with adults undergoing BS and indicating the relationship between macronutrients and weight loss. Titles that did not meet these criteria were excluded. The review was written according to the PRISMA guide, and the risk of bias was according to the Joanna Briggs manual. Data were extracted by one reviewer and checked by another. Eight articles with 2.378 subjects were included. The studies indicated a positive relationship between weight loss and protein intake after BS. Prioritization of protein followed by carbohydrates with a lower percentage of lipids favors weight loss and increases weight stability after BS. Among the results found, a 1% increase in protein intake raises the probability of obesity remission by 6%, and high-protein diet increase 50% weight loss success. Limitations are the methods of included studies and review process. It is concluded that high-protein intake >60 g a 90 g/day may favor weight loss and maintenance after BS, but it is relevant to balance the other macronutrients.
本系统评价评估了肥胖症手术（BS）后宏量营养素摄入与体重减轻之间的关系。于 2021 年 8 月检索 MEDLINE/Pubmed、EMBASE、COCHRANE/CENTRAL 和 SCOPUS 数据库，以搜索符合条件的文章：接受 BS 的成年人的原创出版物，并指出宏量营养素与体重减轻之间的关系。不符合这些标准的标题被排除在外。本综述是根据 PRISMA 指南撰写的，偏倚风险是根据 Joanna Briggs 手册评估的。一位审阅者提取数据，另一位审阅者进行核对。纳入了 8 篇文章，共 2378 名受试者。这些研究表明 BS 后蛋白质摄入与体重减轻呈正相关。优先考虑蛋白质，其次是碳水化合物，脂质比例较低，有利于 BS 后体重减轻和增加体重稳定性。在发现的结果中，蛋白质摄入量增加 1%，肥胖症缓解的可能性增加 6%，高蛋白饮食可使体重减轻成功率增加 50%。研究方法和综述过程存在局限性。结论是，BS 后蛋白质摄入量＞60g/d 或＞90g/d 可能有利于体重减轻和维持，但需要平衡其他宏量营养素。
