Fortunately, people on average only compensate about 30% of the exercise-induced calorie expenditure, which doesn't seem too bad... until we look at the shockingly high variation between individual subjects.

幸运的是，人们平均只代偿了 30% 由运动引起的卡路里消耗，这似乎还不算太糟糕......直到我们看到个体之间惊人的差异。

So, when you take two individual subjects and you join them together, you're creating a two-or-more situation, or a two-or-more subject, therefore you have a plural subject.

所以，当你拿两个单独的主题并将它们连接在一起时，你正在创造一个两个或更多的情况， 或者一个两个或更多的主题， 因此你有一个复数主题。

In some studies, like a study in 2005, this variability in compensation is reflected in the clear variability in weight outcomes between individual subjects, which also shows that compensation tends to be higher in women than men.

在一些研究中，如 2005 年的一项研究，这种代偿的差异反映在个体受试者体重结果的明显差异上，这也表明女性的代偿往往高于男性。
