My 600-lb Life typically shares the stories of one patient as they work to lose weight, but the series shared the stories of cousins Geno Decunto and Nico Martone in a season 11 episode. While some episodes have featured siblings or twins, Geno and Nico are the first pair of cousins to be featured on the show. The support the pair showed for one another was incredibly memorable, as they worked diligently to lose enough weight to qualify for life-changing weight loss surgery. Their episode aired on February 1, 2023, meaning it was likely all filmed in 2021 and 2022.
