In an effort to help prolong his playing career, Ben Roethlisberger cut sugar and carbs from his diet this offseason.
Roethlisberger, 36, worked with a personal trainer this summer.
"Knees, ankles, being lighter -- those are all positives when it comes to this age and playing football, where you're pounding on your knees and you've had a couple of knee surgeries," he said. "Anything you can do to lighten the load on your knees is important."
Roethlisberger confirmed he has lost weight but wouldn't reveal the number.
