6 of 16: EXTREME MAKEOVER: WEIGHT LOSS EDITION - In the premiere episode, "Rachel," trainer and transformation specialist Chris Powell takes on proverbial over-achiever Rachel, who has been able to accomplish nearly everything she has set out to do so far in her young life -- except the one goal that eludes her, to lose weight. At only 21 years old, Rachel weighs nearly 400 pounds. While living at home surrounded by her fit siblings, she feels she's the "elephant in the room." As a result, she believes she can never make her parents truly proud, until she loses weight. However, Rachel soon learns she will get the opportunity of a lifetime when Chris surprises her at the school where, ironically, she teaches young children physical education. "Extreme Makeover: Weight Loss Edition" premieres MONDAY, MAY 30 (10:01-11:00 p.m., ET) on the ABC Television Network. (ABC/Greg Zabilski) RACHEL ( Photo)
