小编摘要:研究表明,喝咖啡确实有减肥的作用。不过,要达到和做一小时运动同等的减肥效果,要喝的咖啡可不是小数目了!

导读:对于不爱运动却想减肥的的MM,咖啡减肥法貌似是一个福音。然而,科学家却不太提倡此道。由于咖啡能使钙质流失,日积月累可导致肌肉萎缩。因此,各位MM一定要三思而后行。喝五十杯(一加仑)咖啡才能达到运动一小时的效果。这样看来,还是运动容易一些。


There's no shortage of scientific research pointing to exercise being good for you, but if you're just trying to lose weight you probably want all the help you can get. Now, research suggests that caffeine activates the same fat-busting genes as an hour's exercise. Somebody, pass the espresso.

A team of researchers from the Karolinska Institute in Stockholm, Sweden, were interested in the genetic activity in the body during exercise. By taking biopsies from the legs of participants, they were able to work out that several genes associated with metabolizing fat are activated by exercise—but only after an hour or so. That means that your body breaks down fat more effectively after an hour's exercise.

But what they also found was that the exact same genes are activated by large doses of caffeine, a finding they report in Cell Metabolism. In fact, the caffeine causes the body to release calcium, which tricks it into thinking that muscles are being contracted—hence the effect.

Sadly, the doses of caffeine required to achieve the same effect as an hour's exercise are... intimidating to say the least. "[You] would need to consume a caffeine equivalent of about 50 cups [of coffee] per day, almost close to a lethal dose", explains Juleen Zierath, one of the researchers, to Nature. Maybe exercise is easier after all.
