2 句子省略问题

During their two weeks on the ultraprocessed diet, participants gained an average of two pounds and consumed about 500 calories more per day than they did on the unprocessed diet. During their time on the unprocessed diet, they lost about two pounds.这句话的during their是不是有省略?还有这个more放在500 calories后面,怎么理解?修饰哪个词?还有on the unprocesse这句话怎么理解了?特别是这个on,这个介词短语做定语吗?

1.500 calories more中的more是限定词,作后置修饰语,修饰名词中心词calories。一般的限定词都是前置修饰语,放在中心名词之前。但少数限定词既可以前置,也可能后置。more就是这样的限定词。

所以我们既可(后置)说500 calories more,更可以(前置)说500 more calories。意思不变,但说500 more calories的更常见。例如:

We need two more days. ( = We need two days more.

2.on the unprocessed diet意为吃未加工饮食,作名词中心词time的定语。During their time on the unprocessed diet, they lost about two pounds全句意为在吃未加工饮食期间,他们大约减重 2
