Christina Phillips
When she first joined the reality TV show, Christina Phillips weighed 708 pounds. Dr. Nowzaradan was shocked when she learned that the young woman had a daily consumption of 7,000 calories. It was a good thing that this is no longer the case. In the follow-up episode, she revealed that she has since lost 538 pounds. This is the highest figure of anyone who has appeared on the show by then. She now weighs 172 pounds and feels great. Aside from that, she has since completed a 5k run for the first time.
Marla McCants
You just know that it is a serious problem when you are among the heaviest people to appear on the show. Marla McCants weighed almost 800 pounds by the time she appeared on the show. She was traumatized when her violent ex was on the run, so she started emotional eating. She has since put her experience to good use by working as a philanthropist and motivational speaker. After she got gastric bypass surgery, she dropped 266 pounds. It looks like this is only the beginning for her. She has not shared her current weight, but you can tell from her photos that she is now happy and healthy!
