美国减肥药和保健品介绍

发胖如山倒、减肥如抽丝,很多人因此绝望,不管什么减肥产品都要试试,导致减肥市场蓬勃发展,包括不需医生处方就可以买的 OTC 药品和保健品,有些号称 FDA approved,有些号称 Clinically tested,到底有没有效?

答案:也许有效、因人而异。但绝没有一种药,吃了之后躺着睡觉就能瘦下来。厂家也知道这个道理,所以包装上都会注明需配合 Diet and Exercise,翻译成白话,就是「管住嘴、迈开腿」

这篇文章不是要教大家怎么减肥,而是比较一下美国常见减肥药和保健品的成分和功效,让大家购买时心里有数。

Orlistat

Orlistat 是 FDA 批准的减肥药,有处方药 Xenical(有效成分 Orlistat 120mg)和非处方药 Alli(orlistat 60mg)两种。FDA 官网说明

Xenical (orlistat 120mg) was approved as a prescription product by FDA in 1999 for obesity management in conjunction with a reduced caloric diet, and to reduce the risk of regaining weight after prior weight loss. In 2007, Alli (orlistat 60mg) was approved for OTC use for weight loss in overweight adults, 18 years and older, in conjunction with a reduced-calorie and low-fat diet.

Xenical 需要医生开处方,Alli 则是非处方药,可以在药店和网上自由购买,应该配合低卡路里、低脂肪的饮食一同使用,用于18岁及以上成人减肥,并且降低减肥之后重新增肥的风险。

FDA 批准的非处方减肥药 Alli
$52.93 购买

作用原理:膳食脂肪需要分解成小分子才能被身体吸收,Orlistat 可阻止分解脂肪的酶起作用,这些未能消化吸收的脂肪就会通过肠道排出体外。但是 Orlistat 对碳水化合物和糖分不起作用,我们中学课本就学过,碳水化合物会被分解为葡萄糖,过量的葡萄糖会转化为脂肪,所以并不是说服用了 Orlistat 就能随便吃也不会长胖。另外,Orlistat 只能阻止你现在吃进去的脂肪被吸收,并不会排出你体内原有的肥肉。

据吃过的朋友说,吃完 Alli 后放屁都可能会带出油,小裤裤没做好防护措施出门会很尴尬!

Meratrim

Meratrim 是一种植物提取的减肥配方,成分是绒毛戴星草和山竹提取物,以3:1比例混合。这种草药混合物的减肥机制还不明确。针对100名 BMI 指数30-40之间超重人士的临床实验中,50人每天服用800mg Meratrim,另外50人服用安慰剂,都遵守每天2000卡路里的饮食、每周内30分钟运动x5天,8周后 Meratrim 组比安慰剂组平均多减了5.2kg体重。感兴趣的人可以去 NIH 官网读论文原文

这个结论令人惊喜,但我持保留态度,因为实验人数少、时间很短,此外严格的饮食和运动起了很大作用,也没有后续跟踪体重有否反弹。

Acetyl-L-Carnitine

中文名乙酰左旋肉碱(很耳熟有没有)。它叫肉碱是不是就真的能肉减?

  • Wiki 词条解释,它能促进脂肪酸进入线粒体进行氧化分解,就是消耗脂肪。
  • 美国最大的医疗信息网站 WebMD 介绍这种成分的时候,主要说它可能有助于改善老人记忆力、减缓因糖尿病导致的神经疼痛等,并未提到有减肥的功效。

一般人通过饮食中的肉类已经能获得足够肉碱,人体内部也能合成一些,没有必要额外补充。通常来说,只有能量消耗很大的运动员和专业健身人士,才需要额外服用左旋肉碱。此外,素食者无法从蔬菜水果中获得左旋肉碱,因此也可以补充。妄图光靠吃左旋肉碱,不运动、不控制饮食就能减肥的人们,醒醒吧!下面是卖得比较好的左旋肉碱产品。

Garcinia Cambogia

Garcinia Cambogia 就是藤黄果,和山竹是亲戚,估计很多人都听说过了。

藤黄果有效成分为 Hydroxy Citric Acid (HCA,羟基柠檬酸),可以抑制脂肪形成,也能提升大脑内血清素水平,于是你没那么快感到饥饿。藤黄果虽然是一种天然植物,但也有副作用,包括头晕、头痛、口干、胃部不适,FDA 曾在2009年发布警告,不要购买一种含有藤黄果提取物的保健品 Hydroxycut,原因是有23个肝损伤案例。该产品中除了藤黄果还有其他成分,当时并未分析出是哪种成分引致肝损伤。

WebMd 建议,藤黄果产品的减肥效用不明显,与其买减肥药,不如注重健康饮食、参加健身课程。

Green Tea

绿茶的减肥作用就更飘渺。现有的理论是绿茶内的咖啡因和儿茶素能加快新陈代谢,以茶代替苏打汽水也能减少热量和糖分摄入,但绿茶并没有直接燃烧脂肪的效果。如果你想试试绿茶的减肥功效,推荐下面几种产品。

CLA

Conjugated Linoleic Acid(CLA)是一种在肉类和乳制品中发现的天然存在的脂肪酸,可以帮助减去脂肪、保持瘦肌肉。WebMD 上面的资料指出,在动物实验中,发现 CLA 还能预防心脏疾病和某些癌症。

2004年的一项实验数据中,180位 BMI 在25-30的肥胖人士,60人服用 CLA 糖浆,60人服用 CLA 药丸,其余60人服用安慰剂。在长达一年的实验里,参与实验的人们并未改变生活习惯,也没有要求做运动,但一年后,服用 CLA 糖浆组减去了9%体脂,服用 CLA 药丸组减去了7%体脂,服用安慰剂组则无变化。

有这么多好处,CLA 却名声没那么响,是因为现在人们对于减肥的意识就是要减体重,而 CLA 在减「脂肪」的同时维持「肌肉」,因而减重效果并不明显,而且至少要连续服用6个月才会看出效果,可是很多人服用了几个星期认为没用便停止了。下面是销量最好的 CLA 产品。

很多健身人士服用 CLA 来增加肌肉,配合强运动和高蛋白饮食。想尝试 CLA 的人请做好长期抗战的心理准备。它也有潜在的副作用,如恶心、增强细胞对胰岛素的抗性、可能造成脂肪肝等。

益生菌

一些益生菌菌株可以降低肠道吸收的脂肪和卡路里的总量,而肠道细菌平衡可能有助于减重、尤其是减少腹部脂肪 []。研究发现对减肥有效的益生菌包括:加氏乳杆菌(Lactobacillus gasseri),鼠李糖乳杆菌 LGG,以及鼠李糖乳杆菌和乳双歧杆菌(Bifidobacterium lactis)的组合 []

在一项研究中,连续服用加氏乳杆菌12周的肥胖男性,体重和体脂显著减少,腹部脂肪减少8.5% []。在另一项研究中,服用鼠李糖乳杆菌 LGG 3周的肥胖女性,体重减轻是服用安慰剂的女性的两倍。并且,服用鼠李糖乳杆菌 LGG 女性能够持续减重,而服用安慰剂的女性的体重会容易反弹 []。推荐辅助减肥的益生菌推荐如下。

Psyllium Husk Powder

Psyllium Husk 是洋车前子的种子外壳磨成的粉,纤维质丰富,遇水凝成胶质状。洋车前子纤维在胃和小肠内不能消化,只有在大肠和直肠内可被细菌部分消化,服用后可增加饱足感,并润肠通便。

所以它是利用吃了后有饱腹感来减少其他食物的摄入,以达到少摄入热量的目的,对于停不下口的人士有一定作用。类似功效的还有奇亚籽(Chia Seed),也是遇水变成凝胶,食用后增加饱腹感。

White Kidney Bean Extract

White Kidney Bean 就是我们吃的白芸豆,花式月饼中常用的食材,本身没有什么味道,适合用来做绿茶月饼、巧克力月饼、果味月饼等……

白芸豆的减肥理论是:从它身上提取出来的芸豆蛋白能抑制淀粉酶的活性,也就是你吃下去的淀粉不会被分解成葡萄糖。不过理论归理论,目前还没有令人信服的实验数据支持。尽管如此,市场上有很多白芸豆提取物的制成品都宣称能减肥。
