With sweeps over, a British chef gets a second crack at the obesity epidemic at a Los Angeles high school. Yanked for poor ratings “Jamie Oliver’s Food Revolution” (7 p.m. and 8 p.m., ABC) returns with back-to-back repeats tonight.

Oliver, whose “Revolution” was set in West Virginia last season, moves to the City of Angels to help change the attitude and the menu at the schools in LA’s Unified School District. But the school bureaucracy shows him the door. He tries to go around the school’s board and win parents and students over by opening a kitchen in Westwood to provide healthy meals and plenty of information about healthier diets. In a second episode, he goes to greater lengths, even disguising himself as a tomato, to get his message across.

Oliver’s onscreen difficulties and the failure of “Revolution” to find an audience demonstrate just how unreceptive folks can be to an “eat-your-vegetables” approach to diet and nutrition. And while Bravo viewers in search of consumer glamour have been suckers for experts with British accents (“Zoey 101,” “Pregnant in Heels”), Oliver’s message and approach has not yet found a network audience.

• Now in its final season, “Friday Night Lights” (7 p.m., NBC) continues to remind us why it’s one of the best network dramas to come along in many years.

Things get hairy when coach Taylor’s (Kyle Chandler) East Dillon Lions take on his old team and crosstown rivals, the Dillon Panthers. Tensions rise when Taylor suspects that somebody from the richer and more suburban Dillon school staff has leaked ugly information to a blog dedicated to insulting the East Dillon players, kids from the wrong side of the tracks.

And Taylor’s role as a mentor to his team of trouble teens is challenged when his star quarterback Vince (Michael B. Jordan) finds himself under pressure from his formerly estranged dad Ornette (Cress Williams) to hotdog it in front of college scouts. The episode does a good job of conveying Taylor’s plight and his difficulty in determining the boundaries between coach and father, team and family. And it doesn’t exactly help that his own daughter (Aimee Teegarden) finds herself in a crisis of her own.

No other show has so brilliantly blended sports and soap opera. And while that hasn’t exactly resulted in a big audience, “Friday Night Lights” will be remembered (or watched on DVD or streamed on the Internet) long after it’s gone from NBC’s schedule.
