When he was an NFL offensive lineman, Alan Faneca weighed 320 pounds. Two years after retiring, Faneca is down to 220.
The 36-year-old Faneca told FOXSportsArizona.com that he cut way down on his caloric intake as soon as he left the NFL, and as a result he lost weight so rapidly that people were getting worried about him.
