1000-Lb Sistersstar Chris Combs may not be the main star of the series, but his experiences with weight loss surgery have been a huge part of the show in recent years, leaving many curious about the details of his operations. Chris, the older brother of 1000-Lb Sisters season 7 stars Tammy Slaton and Amy Slaton, has been part of the series since its early days. Knowing that the show was meant to focus on Tammy and Amy at first, Chris' journey wasn't a big piece of the series right away, but became interesting as viewers got to know him.
