最近,網(wǎng)上有個熱門視頻迅速躥紅,甚至成為微博熱門話題,內容是搬運國外的一個唬人視頻,內容是說低碳水生酮飲食有「五大危害」。 事實果真如此嗎?No! 視頻中聲稱的所有「危害」都是假的。今天,我們就說原理、擺證據(jù)、列事實,掰扯掰扯這個非常有誤導性的熱門視頻。 另外,生酮飲食有一項真正的「危害」,熱門視頻中卻沒說。文末,我們會為你解析。 誤區(qū) 01 低碳水生酮 0000000 會缺維生素、礦物質? 0000000 真相:低碳水生酮飲食不僅不會缺乏任何維生素、礦物質,反而是真正的高營養(yǎng)密度飲食方案。 這是因為,低碳水生酮飲食要求戒除或限制的是糖、面、米等富含精制碳水化合物的食物,而不必限制大多數(shù)蔬菜和低糖水果,熱門視頻中的內容是存在事實錯誤的。 此外,維生素、礦物質最重要的食物來源是肉類、魚類、蛋類、動物內臟、優(yōu)質脂肪等,而不止有蔬菜水果。 低碳水生酮飲食推薦吃肉類、魚類、蛋類、動物內臟、優(yōu)質脂肪、低糖蔬菜水果和堅果,所以,不僅不會缺乏任何維生素、礦物質,反而是真正的高營養(yǎng)密度飲食方案。 科學研究也證實了生酮飲食不會缺營養(yǎng)。例如,今年 10 月剛剛發(fā)表的一篇隨機對照試驗研究(高質量研究)證明:低碳水飲食不會導致任何營養(yǎng)缺乏。 相同結論的科研論文還有很多: 誤區(qū) 02 低碳水生酮 0000000 會降低運動體能? 0000000 真相:適應后,不僅不會降低運動體能,反而可能提高! 從事實來看,大量頂級運動員倡導低碳水生酮飲食,從 NBA 湖人隊大批球星、格斗運動員「嘴炮」、超馬世界冠軍等等,都是低碳水的擁護者。 (圖左為綜合格斗運動員「嘴炮」) 實際上,擼鐵愛好者都知道的傳奇健身組織 CrossFit 也大力倡導低碳水飲食,他們的運動飲食哲學就是「控碳水、邁開腿」(Off the Carbs, Off the Couch)。 視頻里自己也說,低碳水生酮飲食的倡導者,大多是專業(yè)運動員。 也就是說,視頻提出一個「猜想」:低碳水會降低運動體能,盡管很多專業(yè)運動員都倡導低碳水飲食,用「事實」證明低碳水的好處,視頻依然認為自己的猜想是對的。 那么,科學研究怎么說呢? 大量科學研究表明,一旦適應以后,低碳水生酮飲食不僅不會降低運動體能表現(xiàn),反而可能提高耐力、減少疲勞和損傷。 也就是說,低碳水初期,飲食改變會導致適應性反應。等這個適應期度過以后,體能就會逐步改善。 視頻里自己也說,適應期癥狀會在及天之內消失。 ![]() 誤區(qū) 03 低碳水生酮 0000000 效果更容易反彈? 0000000 ![]() 真相:低碳水生酮并不容易反彈,可能更容易堅持。 視頻中聲稱,低碳水生酮的效果「可能會」反彈。 太可笑了!要知道,任何減肥方式,如果錯誤操作、恢復到之前不健康的生活方式,都一定會反彈。但是沒有任何證據(jù)表明,低碳水生酮比其他減肥方式更難堅持、更容易反彈。 相反,有科學研究和大量現(xiàn)實案例證明,通過低碳水生酮飲食減肥成功、改善健康的人群,很多是愿意長期遵循的,因為大家真真切切地看到了自己生活質量的提高,而且并沒有想象中那么難。 ![]() 如果說生酮飲食真的「難堅持」,那么最大原因,應該是不斷有人妖魔化這種飲食,讓本來有機會嘗試堅持的人也失去了勇氣和動力。 誤區(qū) 04 低碳水生酮 0000000 會掉肌肉、掉代謝? 0000000 ![]() 真相:低碳水飲食不僅不會掉肌肉,反而可以防止肌肉流失。 視頻聲稱,低碳水生酮飲食會導致掉肌肉、掉代謝,理由是「低碳水飲食蛋白質吃得少,所以會掉肌肉」。這不是睜著眼說瞎話嗎!低碳水生酮飲食提倡吃肉類、蛋類、魚類等食物,根本不缺蛋白質。 科學研究表明,低碳水飲食不僅不容易掉肌肉,反而比常規(guī)的「限制卡路里」更容易保存肌肉!科學家早就發(fā)現(xiàn),在減脂過程中,低碳水飲食具有防止肌肉分解流失的作用。 ![]() 誤區(qū) 05 低碳水生酮 0000000 增加健康風險? 0000000 ![]() 真相:低碳水生酮不僅不會增加健康風險,反而可以防治代謝疾病。 視頻聲稱,低碳水生酮增加健康風險,這完全是顛倒黑白!他們認為,低碳水飲食吃優(yōu)質脂肪太多,會導致人們更容易患上糖尿病、中風、心力衰竭和癌癥等疾病。 但是,事實和科學研究再次無情地打了他們的臉!大量研究和事實案例表明,低碳水生酮飲食不會導致這些疾病,反而可以預防、改善甚至逆轉! ![]() 原因之一是,「代謝綜合征」和慢性炎癥是導致糖尿病、中風、心臟病、癌癥等多種慢性疾病的最重要風險因素,而低碳水生酮飲食可以有效逆轉代謝綜合征,同時降低慢性炎癥,因此有著非常大的健康益處! ![]() 事實上,低碳水生酮飲食的諸多健康益處,不僅出現(xiàn)在越來越多的前沿科學文獻里,更是已經(jīng)被眾多醫(yī)學專家認可和倡導。 上個月「第二屆全國低碳醫(yī)學大會」在深圳召開,眾多國內外頂尖專家齊聚一堂,大會的主題就是:倡導低碳生活,防治代謝疾病。 ![]() (周華博士、石漢平教授、殷峻教授、楊乃龍教授) 真正的「危害」 0000000 似乎只有一個…… 0000000 低碳水生酮飲食最大的危害,就是它太有「顛覆性」了——它挑戰(zhàn)了傳統(tǒng)健康觀念的刻板教條,并觸碰了大型食品、醫(yī)藥資本的利益。 因此,傳統(tǒng)專家、流量媒體、大型資本既不愿深入研究,也不想承認錯誤。 傳統(tǒng)專家不愿深入研究,因為成本極高; 流量媒體不愿深入研究,因為流量太低; 食藥資本不愿深入研究,因為太難賺錢。 那些想要改善肥胖、代謝健康的人,本來想要學習低碳水健康知識,滿眼看到的卻是主流專家不經(jīng)研究就盲目反對、流量媒體不經(jīng)研究就盲目抨擊。同時,超市里滿滿都是方便又美味的高碳水食物,反正吃病以后還可以吃藥尋求安慰,就沒有動力去了解真正的健康飲食了。 就這樣,錯誤觀念發(fā)展壯大、不斷傳播,腐敗專家、流量媒體、貪婪資本都樂在其中,看上去歲月靜好。如果錯誤觀念一直盛行,耽誤的將是無數(shù)普通人的健康和生命質量。 好在,越來越多的嚴謹專家、良心媒體、創(chuàng)新型企業(yè)和先鋒讀者在不斷努力,用理論邏輯、科研證據(jù)、事實案例和優(yōu)質產(chǎn)品證明這種飲食是安全、健康的。我們期待,每個人可以自由學習健康知識、輕松遵循健康生活方式的時代早日來臨! 如果你也感受到低碳水帶來的益處,歡迎在評論區(qū)分享給大家。 參考文獻: [1] Venables MC, Achten J, Jeukendrup AE: Determinants of fat oxidation during exercise in healthy men and women: a cross-sectional study.
