CHRIS POWELL TAKES ON HIS TOUGHEST CASE YET TO HELP WALLY, A SELF-ADMITTED FOOD ADDICT WHO MAY BE TOO FAR GONE FOR THE TRAINER TO HELP ALONE, ON ABC'S "EXTREME MAKEOVER: WEIGHT LOSS EDITION"

"Wally" -- Wally, a 26-year-old caring husband and loving father, is also a self-admitted fast food addict. Turning to food at an early age to cope with a rough childhood, Wally weighs in at 490 pounds when he meets trainer Chris Powell. Wally's weight loss progress appears to be going well, until Chris receives a troubling email that leads to an emotional intervention. Wally's addiction to food has caused him to spiral downward, and Chris wonders if Wally is beyond the kind of help he can offer, on "Extreme Makeover: Weight Loss Edition," airing MONDAY, JULY 11 (10:01-11:00 p.m., ET) on the ABC Television Network.

Chris puts Wally through intense regimens, including a climb to the top of the Sears Tower in Chicago and a 100-mile bike ride. If Wally can lose 110 pounds during the first of his four three-month phases, his reward for his hard work will be a family trip to Disney World to celebrate his daughter's second birthday.

"Extreme Makeover: Weight Loss Edition" is broadcast in 720 Progressive (720P), ABC's selected HDTV format, with 5.1-channel surround sound. This program carries a TV-PG parental guideline.
