The combination of eating less and getting exercise

could offer double the health benefits when compared to exercise or dieting alone.

Is the usage above a common one?

I believe that “double” can be used as a verb, so I am more used to the expression, could double the health benefits.

Yes, fairly common. Here it is a predeterminer.

Double can be used as an adjective, verb, noun, adverb and even a predeterminer! What a versatile word it is.



It really is!! Thank you very much, AlpheccaStars.
