随着年龄增长发生的瘦体重减轻是定义肌肉减少症的主要终点。此外，肌肉质量的损失是老年人许多不良健康问题发展的核心。因此，瘦体重对营养干预的反应，特别是对膳食蛋白质的反应，一直是一个常用的测量终点。然而，蛋白质摄入量的增加与心血管健康标志物的改善、骨骼健康的改善、体重和代谢疾病的管理以及全因死亡率的降低有关。力量，而不是瘦体重，可能是一个更准确的健康指标，特别是在老年人。蛋白质的建议膳食允许量设定为0.8克/千克/天。由于美国的平均蛋白质摄入量约为1.2 g/kg/天，因此平均蛋白质摄入量似乎高于推荐的膳食允许量，但低于美国国家科学院专家委员会推荐的可接受常量营养素分布范围的下限，也低于美国农业部在膳食指南中建议的膳食摄入量水平。
Loss of lean body mass that occurs with aging is the primary endpoint with which sarcopenia is defined. Furthermore, loss of muscle mass is central to the development of many adverse health issues in the elderly. Consequently, the response of lean body mass to nutritional interventions, particularly to dietary protein, has been a commonly measured endpoint. However, increased protein intake has been associated with improved markers for cardiovascular health, improved bone health, management of weight and metabolic diseases, and reduced all-cause mortality. Strength, rather than lean body mass, may be a more accurate indicator of health, especially in the elderly. The recommended dietary allowance for protein has been set at 0.8 g/kg/day. Because the average protein intake in the United States is approximately 1.2 g/kg/day, it appears that the average protein intake is above the recommended dietary allowance but below the low end of the acceptable macronutrient distribution range recommended by expert committees of the National Academy of Sciences and below the dietary intake levels suggested by the US Department of Agriculture in the Dietary Guidelines.
