斋月间歇性禁食导致了最小的体重减轻,主要是从脂肪质量减少. 细胞内水量减少,表明细胞完整性受损,并在禁食期间发生水位转移.
科学领域:
- 营养和新陈代谢 营养和新陈代谢
- 身体组成分析 身体成分分析
- 身体生理学 身体生理学
背景情况:
- 间歇性禁食,特别是在斋月期间,需要了解它对身体组成和水平衡的影响.
- 无脂肪质量 (FFM) 和体液含量是禁食影响的关键健康指标.
- 评估这些变化对于评估斋月禁食对健康的影响至关重要.
研究的目的:
- 为了评估在斋月禁食期间身体水分区和身体成分的变化.
- 调查斋月禁食对健康个体脂肪量,FFM和体水的影响.
- 为了将身体组成的变化与身体水分分布的变化相关联.
主要方法:
- 一项开放标签的纵向队列研究,涉及73名健康的医疗人员禁食至少20天.
- 使用生物电阻分析 (InBody S10) 测量身体成分和水含量.
- 评估的关键参数包括体重,脂肪量,FFM,全体水 (TBW),细胞外水 (ECW) 和细胞内水 (ICW).
主要成果:
- 参与者经历了大约1,030g (p < 0.001) 的显著体重减轻.
- 脂肪质量显著减少828g (p < 0.001),占体重减轻的80%以上.
- 细胞内水 (ICW) 减少了160mL (p = 0.027),而TBW和ECW保持不变. 在相角减小和ECW/TBW比率增加之间发现了显著的负相关性 (R = -0.71,p < 0.001).
结论:
- 斋月禁食导致了最小的体重减轻,主要是通过减少脂肪质量.
- ICW和相角的减少表明细胞完整性受损,水从细胞内转移到细胞外.
- 这些发现强调了在间歇性禁食期间监测身体成分和水分状态的重要性.
