Obesity rates in people 60 years and older are increasing. While obesity is linked with detrimental health risks, weight loss in this population has previously been considered controversial due to potential worsening of age-related sarcopenia. Protein intake during energy restriction has been linked to lean body mass preservation. No formal guidelines for optimal protein intake during structured weight loss interventions exist for this population, but it appears that the current Recommended Dietary Allowance of 0.8 grams per kilogram of body weight per day may be inadequate. The purpose of this review is to discuss optimal protein intake during structured weight loss interventions in persons 60 years and older with obesity and to present a framework for guidelines to be used by health professionals focusing on weight loss interventions in older adults. Goals for the amount, source, and timing of protein intake, from both food and supplements, are presented and discussed.
60岁及以上人群的肥胖率正在上升。虽然肥胖与有害健康风险相关，但由于年龄相关的肌肉减少症可能会恶化，此前该人群的体重减轻一直存在争议。能量限制期间的蛋白质摄入与瘦体重的维持有关。对于该人群在结构化体重减轻干预期间的最佳蛋白质摄入量，目前尚无正式指南，但目前每天每公斤体重0.8克的推荐膳食摄入量似乎可能不足。本综述的目的是讨论60岁及以上肥胖人群在结构化体重减轻干预期间的最佳蛋白质摄入量，并提出一个框架，供专注于老年人体重减轻干预的健康专业人员使用的指南。本文提出并讨论了食物和补充剂中蛋白质摄入量的数量、来源和时间目标。
