Mona and Andrew

S1 E4: Mona, 41, was a No. 1 Billboard recording artist in the mid-'90s, but the stress of her career caused her to become an out-of-control overeater. After she ballooned to over 400 pounds, she underwent gastric banding surgery, but now binges and purges up to 20 times a day. Meanwhile, Andrew, 23, was a former track star who has battled an eating disorder since childhood. He's frantic to escape the devastating isolation his bulimia has caused, but is afraid to turn to anyone for support. Unless he changes his ways, he is at risk of ending up on the streets or worse--dying.
