1000-Lb Sisters focuses on the Slaton family, who all share a genuine bond with one another, but I think the family could use a few boundaries after seeming too close for comfort in the most recent stretch of episodes. While Tammy Slaton and Amy Slaton were originally the main stars of 1000-Lb Sisters, things have changed as the show has continued along. Tammy, Amy, and their three older siblings Misty Slaton, Chris Combs, and Amanda Halterman have all come into the picture on the series, giving a better idea of what the family is like as an entire unit together.
