# 睡眠、食欲与减脂：研究到底说了什么 同样的饮食下少睡会造就不同的身体：减掉的脂肪更少、流失的肌肉更多，饥饿感也明显更强。 ## 全部研究 - **Effect of sleep extension on objectively assessed energy intake among adults with overweight in real-life settings: a randomized clinical trial** — Tasali E, Wroblewski K, Kahn E, Kilkus J, Schoeller DA (2022), JAMA Internal Medicine 182(4):365–374. 把睡眠延长约 1.2 小时，在没有任何饮食建议的情况下，每日摄入减少约 270 千卡 —— 参与者只是自然吃得更少。 - **The effect of sleep restriction, with or without high-intensity interval exercise, on myofibrillar protein synthesis in healthy young men** — Saner NJ, Lee MJ, Pitchford NW, et al. (2020), Journal of Physiology 598(8):1523–1536. 连续五晚只睡 4 小时使肌肉蛋白合成下降约 18%；在限制期间进行 HIIT 可以保住它。 - **Influence of sleep restriction on weight loss outcomes associated with caloric restriction** — Wang X, Sparks JR, Bowyer KP, Youngstedt SD (2018), Sleep 41(5):zsy027. 在 8 周减重期间每周限制 5 晚睡眠：体重下降相同，但其中来自脂肪的比例更低。 - **Constrained total energy expenditure and metabolic adaptation to physical activity in adult humans** — Pontzer H, Durazo-Arvizu R, Dugas LR, et al. (2016), Current Biology 26(3):410–417. 在高活动量下总能量消耗会趋于平台 —— 即 Galpin 描述的「适应性」代偿。 - **Self-weighing in weight management: a systematic literature review** — Zheng Y, Klem ML, Sereika SM, Danford CA, Ewing LJ, Burke LE (2015), Obesity 23(2):256–265. 频繁称重（每日或每周）与更好的减重和维持相关，且未见成年人出现心理伤害。 - **The role of exercise and physical activity in weight loss and maintenance** — Swift DL, Johannsen NM, Lavie CJ, Earnest CP, Church TS (2014), Progress in Cardiovascular Diseases 56(4):441–447. 单靠运动带来的减重有限，但它与维持减重成果高度相关 —— 这正是 Galpin 5-4-3-2-1 的逻辑。 - **Effects of experimental sleep restriction on weight gain, caloric intake, and meal timing in healthy adults** — Spaeth AM, Dinges DF, Goel N (2013), Sleep 36(7):981–990. 被限制睡眠的成年人在 5 天内增重约 1 公斤，主要来自深夜进食。 - **Impaired insulin signaling in human adipocytes after experimental sleep restriction** — Broussard JL, Ehrmann DA, Van Cauter E, Tasali E, Brady MJ (2012), Annals of Internal Medicine 157(8):549–557. 连续四晚只睡 4.5 小时，脂肪细胞的胰岛素敏感性下降约 30%。 - **Self-monitoring in weight loss: a systematic review of the literature** — Burke LE, Wang J, Sevick MA (2011), Journal of the American Dietetic Association 111(1):92–102. 持续记录饮食和体重是减重成功最有力的预测因素之一 —— 也就是「烘焙师」式做法。 - **Insufficient sleep undermines dietary efforts to reduce adiposity** — Nedeltcheva AV, Kilkus JM, Imperial J, Schoeller DA, Penev PD (2010), Annals of Internal Medicine 153(7):435–441. 在相同热量缺口下，睡 5.5 小时与 8.5 小时相比：短睡组减掉的脂肪少 55%、流失的瘦体重多 60%，而且更饿。 - **Meta-analysis of short sleep duration and obesity in children and adults** — Cappuccio FP, Taggart FM, Kandala NB, et al. (2008), Sleep 31(5):619–626. 综合 30 项研究，短睡与成年人肥胖几率高约 55% 相关。 - **Brief communication: sleep curtailment in healthy young men is associated with decreased leptin levels, elevated ghrelin levels, and increased hunger and appetite** — Spiegel K, Tasali E, Penev P, Van Cauter E (2004), Annals of Internal Medicine 141(11):846–850. 连续两晚只睡 4 小时，胃饥饿素升高、瘦素下降，食欲增加约 24%，尤其偏向高热量碳水。 - **Impact of sleep debt on metabolic and endocrine function** — Spiegel K, Leproult R, Van Cauter E (1999), Lancet 354(9188):1435–1439. 健康年轻男性连续六晚只睡 4 小时后，糖耐量下降、傍晚皮质醇升高。 --- 这是对已发表研究的科普性总结，不构成医疗建议。筛查得分不是诊断。若得分偏高或身体不适，请咨询医生。 SleepShred for iPhone: https://apps.apple.com/app/id6802040541
