J AM Coll Nut:素食是更有效的减肥方法

2017-06-12 MedSci medicalxpress

一项发表在《美国营养学杂志》上的新研究发现,与传统的低卡路里饮食者相比,素食主义者不仅减肥效果更好,而且还能通过减少肌肉脂肪,改善新陈代谢。该研究的主要作者、华盛顿医学委员会临床研究主任Hana Kahleova博士说,失去肌肉脂肪可以改善葡萄糖和脂类代谢,因此这一发现对代谢综合征和2型糖尿病患者尤为重要。有74名2型糖尿病患者被随机分为素食组或常规的抗糖尿病饮食组。素食主义者的饮食包括蔬菜、谷物

一项发表在《美国营养学杂志》上的新研究发现,与传统的低卡路里饮食者相比,素食主义者不仅减肥效果更好,而且还能通过减少肌肉脂肪,改善新陈代谢。

该研究的主要作者、华盛顿医学委员会临床研究主任Hana Kahleova博士说,失去肌肉脂肪可以改善葡萄糖和脂类代谢,因此这一发现对代谢综合征和2型糖尿病患者尤为重要。

有74名2型糖尿病患者被随机分为素食组或常规的抗糖尿病饮食组。素食主义者的饮食包括蔬菜、谷物、豆类、水果和坚果,而动物产品每天最多只能吃一份低脂酸奶。传统的抗糖尿病饮食遵循欧洲糖尿病研究协会的官方建议(EASD)。这两种饮食每天都受到500千卡热量的限制,且每个人的热量摄入相同。

人们发现素食者的减肥效果几乎是正常饮食的两倍,分别减去6.2kg和3.2kg。使用磁共振成像,Kahleová博士及其同事们研究了受试者大腿上的脂肪(脂肪储存)组织,以了解两种不同饮食如何影响皮下,筋膜下和肌内脂肪(即皮下脂肪, 肌肉和肌肉内部的表面)。

他们发现,这两种饮食都导致皮下脂肪的减少。然而,只有素食者的筋膜脂肪减少,而且其肌肉内的脂肪也减少得更多。

这一点很重要,因为2型糖尿病患者的低筋膜脂肪与胰岛素抵抗有关,因此减少它对葡萄糖代谢有有益的影响。此外,减少肌肉内脂肪可以帮助增强肌肉的力量和灵活性,特别是在患有糖尿病的老年人中。

Kahleová博士说:"素食证明是减肥最有效的方法。然而,我们也发现素食在减少肌肉脂肪方面更有效,从而改善新陈代谢。这一发现对于那些试图减肥的人来说很重要,包括那些患有代谢综合症和/或2型糖尿病的人。但是,对于重视体重管理,要保持精益健康的人来说,这也是相关的。"
