Al Thornton changed diet

The 6-foot-8 Thornton hired a personal chef in the off-season and abstained from greasy foods as he dropped from 235 pounds to 230, but felt his quickness came only in spurts. Thornton couldn’t pinpoint when he fully adapted to his diet, but said his energy level recently has been high.

“It took awhile,” said Thornton, who ate chicken breast, pasta and tomatoes after Thursday’s practice. “Once you do it you can tell there’s a major difference to how you feel and how your body feels. It’s an adjustment. But if you want to do well in this game, sometimes you have to make sacrifices.”

Thornton doesn’t want that sacrifice to include a bench role, but Coach Mike Dunleavy strongly hinted that rookie forward Blake Griffin will take Thornton’s place whenever Griffin fully recovers from the stress fracture in his left knee.
