這馬的人因為食傷濟閣欠運動,腹肚愈來愈大,各種減肥中心的生理嘛綴咧那來那交易。雖罔人人攏知欲減肥就愛減食閣骨力運動,也就是講予消耗的能量比食入來的較濟就會使矣!毋過因為種種因素,大箍人欲減肥並無簡單(是按怎大箍人欲減肥會遮艱難?)。舊年一篇新研究顯示,咱人一工的新陳代謝會有週期性變化,若佇特定的時間做運動、食三頓,無定著對減肥會有大幫贊喔。

人佇下晡使用上濟熱量 Lâng tī ē-poo sú-iōng siōng-tsē jia̍t-liōng
根據醫學研究,人活動所消耗的能量干焦占整體能量消耗的15-30%,大多數的能量是用佇維持性命的「基礎代謝」,基礎代謝率 (basal metabolic rate, BMR) 是咱人佇靜靜倒佇眠床的狀態之下,所消耗的上低熱量,伊平均會使用65-70%的能量,所以有學者認為,提升基礎代謝率,會使講是上有效率的減肥方法。而且佇基礎代謝率當咧旺的時陣食物件,嘛較袂因為營養過剩造成體內脂肪堆積。毋過,到底人的基礎代謝率是固定的,或者是會綴時間變化?一直是一个誠受爭議的議題。舊年11月,美國哈佛大學的教授Jeanne Duffy所領導的團隊,佇《當代生物學》期刊發表一篇論文,顯示人的基礎代謝率是有週期性變化的,伊佇下晡的時陣上懸,平均比上低的半瞑仔加百分之十。Duffy閣發見這个現象受生理時鐘調控,和人的活動、外界環境無底代。

實驗過程 Si̍t-giām-kuè-thîng
佇這个實驗裡,Duffy 揣來七个38至69歲的實驗志願者,予𪜶蹛佇一間無時鐘、無窗仔、無電話和網路,佮外界完全隔離的房間,來研究生理時鐘和基礎代謝率的關係。不過逐个實驗志願者原本的生活攏無仝款,比論講有人慣勢晏睏晏起來,有人慣勢早睏早起床,有人慣勢佇固定時間做運動等等,為著莫予遮的因素影響著實驗,Duffy逐工攏共𪜶的睏眠佮起床時間延後四點鐘,就敢若予𪜶佇一禮拜內踅地球一輾。佇這種狀況之下,𪜶的生理時鐘無法度調整甲和外界時間同步,會完全按照伊自然的週期運作,紲落去Duffy就會當精確觀察𪜶的基礎代謝率綴生理時間的變化矣。

Duffy予逐位實驗志願者縖可比度針的感測器,來量𪜶的核心體溫,因為咱的核心體溫反應咱身體使用熱量的效率,透過觀察志願者的核心體溫的變化,Duffy就會使了解佇每一工的無仝時間裡,逐个人的基礎代謝率的懸低。𪜶的結果顯示,基礎代謝率上低的時陣是半瞑到透早這段時間,紲落去會開始回升,到下晡五點左右達到上懸。

醫學文獻其實早就發見定定輪班抑是愛食消夜的人,未來會較𠢕大箍、以及較𠢕著親像糖尿病、癌症、認知障礙等等的病症。Duffy表示𪜶的研究結果暗示講遮的慢性病的致病因端可能和生理時鐘受擾亂有關。不而過,Duffy嘛承認講𪜶的實驗干焦有七个志願者,算是誠初步的結果,未來閣需要較濟的研究來驗證。
