I was reading this [answer](https://japanese.stackexchange.com/a/5926/45630)
and I came across this:

> **(A)** 何もしないで暖かくする (ambiguous)

> **(B)** 何もしなくて暖かくする (unambiguous)

I'm not sure why **A** is ambiguous, but here's my understanding: unlike なくて,
ないで doesn't imply a cause, so it could either mean that not doing anything
keeps you warm or not. However, in the same answer, it says that **B** does
not mean "keep the body warm _by_ not doing any activity," which contradicts
what I know about なくて, that is, it implies a cause. In other words, I would
translate both as follows:

> **(A)** 何もしないで暖かくする。
>

>> Somebody doesn't do anything **and** keeps warm.

>>

>> _not necessarily_ Somebody keeps warm by not doing anything.

> **(B)** 何もしなくて暖かくする。
>

>> Somebody keeps warm **by** not doing anything.

>>

>> _not_ Somebody doesn't do anything and keeps warm.
