Pack on lbs

I gained 10 pounds in one month by eating right before going to bed.

Thats how I would say it

Thanks for the reply. But I want to use the phrasal verb "pack on". I believe they can be interchangeably used.

They can not, in the sense that it sounds weird..perhaps, "I (now) pack 10 extra pounds since i started eating right before going to bed one month ago."

For formal and literal English , "gained 10 pounds.." is good English.

"Packed on pounds..." is more of a amphetic way to mean "gained 10 pounds" colloquially

Are you saying "gain pounds" and "pack on pounds" can't be used interchangeably?

cheers

Aside from the fact that "pack on" is an informal phrase, how does the rest of the sentence sound?

Thank you for the help, DE. I have one more question, though.

ex1) Leonardo DeCaprio packed on the pounds to play 'J. Edgar'.

ex2) These 10 foods, although nutritious, can still pack on the pounds.

Could you explain why the definite article "the" is present in these sentences?
