We've seen several stories recently about NFL offensive lineman dropping serious weight after retiring.

But Alan Faneca, the former Pittsburgh Steelers stalwart who made nine All-Pro teams, took the whole "slimming down" thing to a new level.

Not only did Faneca drop more than 100 pounds, he also has started running marathons. He recently completed his first race, the New Orleans Rock & Roll Marathon.

Faneca, 37, says he has reduced his daily calorie intake to 1,800 a day. He went from a playing weight of 320 pounds to about 215 now.

"For athletes, when you stop [playing] you have to realize you can’t keep eating the things you were eating because you’re not doing the things you were doing,” Faneca told Runners World.

Faneca, who starred collegiately at LSU, was selected by the Steelers with the 26th overall pick of the 1998 NFL draft. He played for the Steelers, Jets and Cardinals during his 13-year career and was named to the Pro Bowl in each season from 2001 to 2009. He retired in 2011.
