长难句分析

1. However， this didn't mean they found a relationship between eating later and gaining weight per se（本身），rather that timing of when you consume calories， relative to your own biological timing，may be an important factor for your health.然而，这并不意味着他们发现了吃得晚与体重增长本身的关系，而是发现了什么时候摄入热量，与自己的生物钟相比较，可能是影响健康的重要因素。

这是个复合句。主句是this didn't mean...后面的宾语从句中又有宾语从句，这个宾语从句主语是a relationship，谓语是may be，后面是表语，其中between后面是定语，rather“而不是”后面的内容和between...and...连接的内容并列，relative to的介词短语做calories的定语。

2. We actually hypothesize that the mechanism driving this result is a lower amount of energy expended to break down food that is consumed during the night， as we have shown that to be true during controlled laboratory studies.我们实际上假设导致这一结果的机制是夜晚摄入食物时，分解食物的能量更低，在控制实验研究中，这一假设被证明是正确的。

这是个复合句。第一个that是hypothesize的宾语从句，第二个that是food的定语从句，as引导的是非限制性定语从句，as表示“正如”之义。
