If I was fat, and now I'm not, which is better: 我长胖 or 我长胖了 or 我长了胖 or 我长了胖了? Suppose in the past I was fat, and now I'm no longer fat.  I'm wondering which 了 is appropriate:


我长胖
我长胖了
我长了胖
我长了胖了


I don't think we can just leave off the 了.  It makes sense to put 了 at the end as a change-of-state 了.  However, it also seems to make sense to use a completion 了 after the verb (which I believe is 长).  Yet the double 了 doesn't seem to apply here.

Baidu results indicate both 我长了胖 and 我长了胖了 are plain wrong (but suggests 我长了肥胖 is possible).  I don't understand why.

Question: If I was fat, and now I'm not, which is better: 我长胖 or 我长胖了 or 我长了胖 or 我长了胖了?
Neither.

If you used to be x and you're not any more you'd just use a construct like:


  以前很x


like:


  (我)以前很胖




Of course, 很 doesn't necessarily mean really or very, but if you want to change it to 有点 that's cool too:


  (我)以前有点(儿)胖
