But the major difference is in fat mass.

主要的区别在于脂肪的重量。

With higher protein intake, fat mass dropped by a significantly higher 1.6 kilograms.

然而高蛋白组的体重却显著降低了1.6千克。

Fat mass decreased, on average, by only 0.3 kilograms in lower-protein subjects, which is not statistically meaningful.

平均的脂肪重量是下降的低蛋白组只下降了0.3千克，这在统计学上差异并不显著。

The data focused primarily on two measurements: changes in fat mass and fat-free mass.

脂肪块的变化和无脂肪块的变化。

And so that's probably having an effect on fat mass.

所以这可能会对脂肪量产生影响。

Also, bulking will not only increase muscle mass but because of the weight gaining nature of it, it will increase your fat mass.

此外，增肌不仅会增加肌肉质量，而且由于体重的自然增加，它也会增加你的脂肪质量。

One lone research in 2016, using sarcopenic older men, did find that 12 weeks of collagen paired with resistance training significantly increased lean mass and strength while reducing fat mass.

在 2016 年有一项研究，针对的是有肌肉流失症的老年人，确实发现12周的胶原蛋白搭配抗组训练显著增加了肌肉量和力量，同时减少了脂肪量。

After the researchers compiled and analyzed the data, the results were pretty clear: Interval training and steady state cardio resulted in similar changes in both fat mass and fat-free mass.

在研究人员整理和分析了数据之后，结果非常清楚：间歇训练和稳定状态的有氧运动在脂肪块和无脂肪块上产生了类似的变化。

Especially when previous studies, like a 2012 study by Bray et al, found a very clear and distinct positive relationship between lean body mass and protein intake with no difference in fat mass.

特别是在2012年，Bray 等人研究发现在去脂体重和蛋白质摄入量之间，有很明显的正相关，同时脂肪含量不受影响。
