My 600-lb Life season 8's Dominic Hernandez was a difficult case for the Houston-based Dr. Younan Nowzaradan, and since his episode aired, he's continued on his weight loss journey. Patients seek out the help of Dr. Nowzaradan, usually known as "Dr. Now," in order to lose enough pounds to qualify for bariatric surgery. They also prepare themselves for the lifestyles they'll need to maintain after their operations. While Dr. Now's plans can be tough on patients, his methods work if they are dedicated, and truly prioritize their health. Some patients have difficulty staying on strict diets, and stop following Dr. Now's instructions.

Originally weighing in at over 650 pounds, Dominic had some circumstances that were not necessarily conducive to weight loss. However, My 600-lb Life's Dr. Nowzaradan thought that Dominic would be a great candidate for his plan. Dominic was homeless, which made it difficult for him to maintain a healthy diet or exercise routine.
