随着一天天衰老，我们的身体消耗热量的功能逐渐减弱。

As we get older, our bodies become less efficient at burning up calories.

《牛津词典》

减少的肌肉也会降低你的身体消耗热量的速率，这令你保持健康的体重或者减去多余的脂肪变得更具挑战性。

Less muscle mass also decreases the rate at which your body USES calories, which can make it more challenging to maintain a healthy weight or lose excess pounds.
