"David & Rebecca" -- Twins David & Rebecca didn't think that much about their weight as they were growing up in North Prairie, WI. David, who weighs in at 470 pounds and Rebecca, who weighs 398 pounds, spent their childhood making people laugh. Behind the smiles however, there were tears of pain caused by a difficult upbringing, which led them to use food as an outlet. After Chris Powell decides to help David and Rebecca on their 23rd birthday, he realizes the twins are extremely co-dependent and have been enabling each other's poor decisions for years, especially when it comes to their weight. After a tearful goodbye, the twins are split up for a 90-day challenge, with Rebecca going to Arizona to work alongside Chris's wife, Heidi. At the beginning of his weight loss journey, David said he always wanted to go through Navy SEAL training to show his dad that "he was a man." Chris takes the twins on his toughest milestone challenge to a rigorous "Kokoro" training camp designed to forge mental toughness and modeled off the famous Navy SEAL Hell Week. But when the twins' old habits begin to creep back in, Chris is truly concerned that they may not be able to meet their weight loss goals. Find out what happens on the Season Premiere of "Extreme Weight Loss," (formerly known as "Extreme Makeover: Weight Loss Edition,"), TUESDAY, MAY 28 (8:00-10:00 p.m., ET) on the ABC Television Network.
