Just so you can see the difference, here is Kevin competing at the 1999 Olympia the next day:
http://www.youtube.com/watch?v=HjWfP5QyahI&mode=related&search=It's true that Kevin had almost nothing in his fridge pre-contest. Maybe some frozen fish and broccoli and that's it.
Levrone was all about discipline with a capital D. 100% dedicated to being the best at whatever he does. The guy never cheated on his diet, never skipped a workout, never sacrificed his sleep to grab some ass. Unlike some guys who get headshots and try to get cast in a movie, Kevin spent big bucks to train with New York and Hollywood's top acting coaches, and the guy hired a PR firm and a top talent manager. The result is that he's done 3 movies already for good money while he continues to improve his acting chops. If you know Kevin, you know that he won't stop until he is headlining a Jerry Bruckheimer-produced Tony Scott-directed action movie. Don't doubt him.
To answer the other question, after the 1999 Olympia, he and his wife separated and the Smiths helped him with his food prep for the 2000 Olympia. They were also co-owners of his World Gym until he bought them out. They were shady people and he no longer associates with them.
