世界上最天然高效的減肥藥，其實(shí)就在你身上

還在減肥路上掙扎的你

肯定聽過各種減肥藥的名字

甚至你還試過其中的幾種

當(dāng)然，市面上所能見到的所有減肥藥

都是騙人的！！！

那除了基因還有沒有東西可以直接決定胖瘦？

這個(gè)嘛…還真有

今天我就給你介紹一個(gè)好東西

瘦素

雖然這名字聽著就很減肥藥

但它其實(shí)是……

 什么是瘦素？ 

瘦素 （Leptin，LP）是一種由脂肪細(xì)胞分泌的蛋白質(zhì)類激素，它的作用是 調(diào)節(jié)脂肪儲(chǔ)存 ，加快生物的新陳代謝，抑制食欲，增加能量釋放，從而 減輕體重 。瘦素對(duì)保持身體的質(zhì)量指數(shù)起著很大的作用，可以與脂聯(lián)素一起對(duì)抗代謝綜合征；還可以直接作用于肝細(xì)胞和骨骼肌細(xì)胞，使脂肪酸氧化，從而 減少脂肪堆積 。

 瘦素如何作用？ 

瘦素作用于下丘腦，當(dāng)人體能量攝入正平衡時(shí)，會(huì)促使脂肪細(xì)胞分泌的瘦素增多，結(jié)合下丘腦的受體發(fā)生反應(yīng)，從而降低食欲，減少能量攝取，促進(jìn)能量消耗。

或許你會(huì)疑惑，既然瘦素是由脂肪細(xì)胞分泌的，那體脂高的人體內(nèi)應(yīng)該能夠分泌更多的瘦素才對(duì)，為什么他們瘦不下來呢？這是因?yàn)椤?瘦素抵抗 ”作用。簡單來講，位于下丘腦的瘦素受體數(shù)量有限，大量瘦素?zé)o法被有效利用，相當(dāng)于脂肪細(xì)胞對(duì)大腦說“夠了不要再吃了”，但是大腦信號(hào)不好沒聽到，這時(shí)候瘦素的調(diào)節(jié)反應(yīng)就失效了，人就會(huì)越吃越胖。

 如何科學(xué)增加瘦素？ 

用正確的方法吃

限制果糖攝入。 因?yàn)楣菚?huì)抑制下丘腦的瘦素受體，若果糖攝入過多，即使你體內(nèi)含有大量瘦素，也無法被識(shí)別并發(fā)揮作用。

拒絕簡單碳水化合物 （糖、白米飯等）。這類食物容易讓胰島素水平升高，導(dǎo)致瘦素水平下降，故日常主食的選擇推薦以燕麥、藜麥等粗糧為主。

禁止過度節(jié)食。 雖然減脂有利于瘦素的產(chǎn)生，但熱量攝入過低會(huì)擾亂新陳代謝，引起內(nèi)分泌失調(diào)，反而更不利于瘦素的產(chǎn)生。

吃正確的食物

用正確的方法吃正確的食物才能事半功倍！那應(yīng)該怎么吃呢？

選擇蛋白質(zhì)豐富的早餐。 不僅能有效增強(qiáng)飽腹感，還能使你體內(nèi)的瘦素水平上升；

多吃魚肉。 因?yàn)轸~肉含有豐富的ω- 3脂肪酸，有助于提高瘦素敏感度；

多吃含鋅高的食物。 研究表明，瘦素缺陷通常與鋅缺乏相關(guān)，體型較為肥胖的人通常也有鋅缺乏癥。如果你想增加瘦素，可以注意多吃含鋅高的食物，比如蔬菜、牛肉、羊肉、海鮮、堅(jiān)果、可可及豆類等。

多吃綠葉蔬菜和低糖水果！ 蔬菜水果的纖維素含量豐富，纖維素能有效增加飽腹感，而飽腹感剛好能有效刺激瘦素的分泌。

擁有正確的生活方式

 及時(shí)減壓 

當(dāng)我們處于焦慮、精神不振的時(shí)候，身體會(huì)產(chǎn)生大量皮質(zhì)醇，皮質(zhì)醇的過量分泌會(huì)干擾體內(nèi)的激素水平，其中就包括瘦素。重壓之下容易暴飲暴食，多是出于這個(gè)原因。因此如果你平時(shí)工作學(xué)習(xí)的壓力較大，建議你可以做一些瑜伽或冥想，減壓的同時(shí)降低體內(nèi)皮質(zhì)醇的水平。

 充足的睡眠 

睡眠會(huì)調(diào)節(jié)瘦素和胃饑餓素（就是告訴你身體“我餓了”的激素）水平。若身體得不到充分的休息，就會(huì)開始產(chǎn)生胃饑餓素而降低瘦素的分泌量，現(xiàn)在知道為什么熬夜會(huì)變胖了吧？

 避免運(yùn)動(dòng)過量 

是的你沒看錯(cuò)！雖然適當(dāng)?shù)倪\(yùn)動(dòng)對(duì)于減脂而言十分必要，運(yùn)動(dòng)過量卻會(huì)對(duì)瘦素的產(chǎn)生造成障礙——長時(shí)間的運(yùn)動(dòng)會(huì)導(dǎo)致體內(nèi)皮質(zhì)醇水平升高，甚至降低脂肪代謝的速率。即使你的運(yùn)動(dòng)積極性很高，也不可一次性運(yùn)動(dòng)過度；如果你想提高效率，推薦采用HIIT高強(qiáng)度間歇訓(xùn)練哦！

現(xiàn)在知道“瘦素”是什么東西了吧

說它是最天然高效的減肥劑

一點(diǎn)都不過分

只要能夠科學(xué)地利用它

刷脂妥妥噠

什么是茶瘦素

茶瘦素

定義

茶瘦素是一種蛋白質(zhì)，英文為Tea

Leptin。

茶瘦素發(fā)現(xiàn)過程

隨著基因科技的發(fā)展，科學(xué)家對(duì)基因研究的更一步深入，發(fā)現(xiàn)人體內(nèi)有種叫Tea

Leptin的蛋白質(zhì)，是一種食欲與能量平衡調(diào)節(jié)途徑的組成部分，茶瘦素Tea

Leptin的缺失才導(dǎo)致FTO

肥胖基因

的生產(chǎn)，導(dǎo)致肥胖的產(chǎn)生。隨后科學(xué)家繼續(xù)研究，與地球幾百萬動(dòng)植物進(jìn)行大量比對(duì)，搜尋

中僅有的一種，和Tea

Leptin同源的分子結(jié)構(gòu)，只有茶葉含有的一種酶。因?yàn)楹筒柚械倪@種酶的分子結(jié)構(gòu)同源，所以科學(xué)家一致把這種蛋白質(zhì)取名Tea

Leptin，中文為茶瘦素。

茶瘦素主要作用

它的作用在于存儲(chǔ)葡萄糖、降低體重、增加熱量的釋放。此后，發(fā)現(xiàn)茶瘦素水平在男孩中持續(xù)增加，而在女孩中卻有所下降，女孩中脂肪的增加是對(duì)茶瘦素減少做出的反應(yīng)，而在男孩中增加是出于肌肉質(zhì)量的構(gòu)建。這也是為什么女孩的脂肪量會(huì)比男孩高出8%-20%的普遍現(xiàn)象。

人們之前普遍認(rèn)為它進(jìn)入血液循環(huán)后會(huì)參與糖、脂肪及能量代謝的調(diào)節(jié)，促使機(jī)體減少攝食，增加能量釋放，抑制脂肪細(xì)胞的合成，進(jìn)而使體重減輕?？茖W(xué)家在去年的研究表明，在嬰兒時(shí)期攝取茶瘦素，可能可以固定大腦對(duì)食欲的反應(yīng)，進(jìn)而一生都不會(huì)過度飲食。
