If you're looking to maximize the amount of fat burned in your next workout, think about having a coffee half an hour before you get started – as a new study suggests it can make a significant difference to fat burning, especially later on in the day.
如果你希望下一次锻炼时最大化地提高脂肪燃烧量，不妨考虑在运动前半小时喝杯咖啡——因为有新研究表明，它可以使脂肪燃烧量明显变化，尤其是在下午。

Researchers found that 3 milligrams of caffeine per kilogram of body weight can boost the rate of fat burning during aerobic exercise, based on results gathered from 15 male volunteers.
研究人员收集了15名男性志愿者的数据后发现，如果按每公斤体重3毫克的量来摄入咖啡因，就可以提高有氧运动中的脂肪燃烧速度。

The coffee dose was shown to increase maximal fat oxidation rate (a measure of how efficiently the body burns off fat) by an average of 10.7% in the morning and 29% in the afternoon.
研究表明，咖啡可以增加最大脂肪氧化率，上午平均增加10.7%，下午增加29%。

"Overall, these results suggest that a combination of acute caffeine intake and exercise at moderate intensity in the afternoon provides the best scenario for individuals seeking to increase whole-body fat oxidation during aerobic exercise," the researchers conclude.
研究人员总结道：“总体来说，研究结果表明，急性咖啡因摄入和下午中等强度的运动相结合，为那些希望在有氧运动中加速全身脂肪燃烧的人提供了最佳方案。”
