Tiffany aka Pearls, 36, has food issues stemming from her junior high days when she starting taking diet pills and starving herself. Now she is looking for a change. Not only is she dealing with her own issues but she a single mom to a special needs son who has autism. She also has an estranged stepson with autism that she wishes to see again. When her husband left her she started her unhealthy relationship with food once again and now she's 150 pounds overweight.

Pearls gets her acceptance to the Chris and Heidi club at the 5k she organized but didn't plan on running. Until Heidi forces her of course. Heidi wants this Pearls challenge because she, too, suffered from eating disorders as a teen. She can relate and she can help. Weighing in at 296 pounds she is kissing that number goodbye and moving on.

The 90 days in Colorado has a goal of losing 220, her choice (Chris thinks she's choosing the easy way out). She also asks Chris to run a high-heel race alongside her as one of her other future goals. He agrees if she meets her Phase I goal. To teach her power over her food she has to take care of a bag of cheese puffs like a baby for the entire 90 days. Good luck. The real issue is her feeling like a failure in life and in this transformation. Too help her with her relationship with food she gets to meet with Rocco Dispirito as a healthy food coach and also gets encouraged by Heidi to reach out to her ex to reunite with her stepson. When he won't return calls or texts Heidi calls him herself, but he still declines the opportunity. Now the challenge is to close that chapter rather than reopening it. There is one drawback already in her journey, however. She has a tear in her medial meniscus. The doctor says she needs to be off her knee for two months causing Pearls to break down emotionally. Heidi says she can still work out other parts of her body and the doctor says Pearls must be 100% on her diet. At her 90 day weigh in she is down to 215, 81 pounds lost. Chris makes good on his promise to run a high-heel run with her. ::Whistles at his sexy legs:: This is what quads and calves really feel like, Chris.

Phase II means another 45 pounds to lose. If she meets her goal she will get to train with Cirque de Soleil. Plus she gets to meet her idol, and fellow autism mom, Holly Robinson Pete who is a huge autism awareness advocate and founder of the Hollyrod Foundation. At her weigh in she is down to 165, 50 pounds down.

Phase III brings on more trouble. She's seeing the weight on the scale go up and it's making her feel fat and depressed again, causing moments of relapse thoughts. She weighs in at 161, only 4 pounds down. Seeing the doctor changes how Pearls feels about her lack of weight loss. She's down to 27% body fat and she's and excellent candidate for skin removal surgery.

At her final weigh in She is down to 147 pounds and looking fabulous! Her son, Mason, is also down 25 pounds thanks to Seth Rollins, the current WWE World Heavyweight Champion.
