我比以前胖英语

我个人觉得如果现在以前都属于瘦，那中心词应该是瘦thin，所以翻译为
I used to be thinner .

如果现在以前都属于胖，那中心词应该是胖fat,所以翻译成
I'm fatter than before.
I'm fatter than I used to be .

你觉得对吗？

I gained much weight than before.
还是含蓄一点吧````外国人一般不这么说"fatter than before"....

I'm becoming fatter than before.

I am fatter than I uesd to

fat不是有贬义么？
i used to be thinner`
