Short-Term Fasting Made Mice Healthier

短期禁食的小老鼠更健康

When it comes to diet, weight gain and diabetes, it;s not just what we eatbut when we eat.

谈到饮食、体重增加和糖尿病,它不仅关系到我们吃什么的问题还关系到我们什么时候吃的问题。

\Satchidananda Panda, a researcher at the Salk Institute for Biological Studies in La Jolla, California.

萨特旦安达潘达,加利福尼亚州拉荷亚索尔克生物研究所的一名研究员。

Panda and his team had mice engage in what;s called time-restricted-feeding. That is, the mice consumed all their daily calories in an eight-to-12-hour window. And they wound up with markers for health that were better than those of mice free to eat whenever they wanted. For example, time-restricted-feeding reduced whole body fat, inflammation and insulin resistance and improved the mice;s glucose tolerance.

潘达和他的团队找来一些小老鼠进行时间限制饲养实验。即小老鼠所有的日常卡路里都在一个8到12小时的窗口里消费。结果它们身上的健康标签比那些随时可以自由吃食的小老鼠都要好。例如,时间限制饲养降低了它们的全身脂肪、炎症及抗胰岛素性并提高了小老鼠的葡萄糖耐量。

We were surprised to find that the benefits of time restriction persist even if the mice take the weekends off. So binging on Saturday and Sunday did not wipe out the positive effects. The study is in the journal Cell Metabolism.

我们惊讶地发现,即使周末让小老鼠休息不做实验,时间限制饲养的好处仍然有效。所以即使周六周日随意吃食也并没有消除实验的有效性。该项研究发表于《细胞代谢》杂志上。

What is very exciting about this is that it;s much easier to adopt than most of the lifestyle modifications that people are recommended in doctors; offices every day.

最令人兴奋的是,它比大多数医生向人们推荐的改变生活方式的办法都更容易采取。

Gastroenterologist Amir Zarrinpar, one of the study;s authors

胃肠病学家阿米尔,该研究报告的作者之一。

So with this type of therapy you don;t really have to calorie count. What really this works on is your own biology and letting your body use its own evolutionary-developed metabolic pathways to shuttle energy appropriately.

因此用这种治疗方法,你无需再去计算卡路里。这种治疗其实是对你的生理机能起作用,让你的身体通过自身进化发展的代谢途径来适当地运送能量。

These findings are very exciting, but they;re in mice. We need to do further experiments to make sure that they also lead to therapies in humans.

这些发现非常令人振奋,但它们仅适用于小老鼠。我们需要进一步实验来确定,这些发现同样也能适用于治疗人类。
