Meaning, she's been gaining weight so she can't put on her pants. "You aren't the only one!" Here's the double entendre. He means that he, too, has been gaining weight, but its second meaning is that he hasn't been getting into her pants lately. "I mean, I've put on some pounds myself." Clarification on what he actually meant.
