Weight loss reality show My 600-lb Life follows morbidly obese people who have chosen to get medical support and shed pounds for their own wellbeing. While the series is certainly fascinating, it can be frustrating (and even triggering) for some to watch. Many My 600-lb Life stars are unable to lose the weight, or end up relapsing after seeking the professional help from Dr. Younan Nowzaradan (Dr. "Now"). There have even been several deaths after the episodes aired.However, My 600-lb Life success stories do exist, and there have been a number of individuals who have worked hard to lose the weight, adopted a healthier diet and lifestyle, and managed to stay on track. And their transformations are incredible.Brittani Fulfer from Season 4Brittani Fulfer joined My 600-lb Life when she weighed 604 pounds. She now weighs 222 pounds, and is super proud of her progress.

I was miserable, and I knew I had to do something," she told Women's Health.Watch My 600-lb Life on TLC every Wednesday at 8 p.m. EST.
