1000-Lb Sisters star Tammy Slaton has lost an impressive amount of weight over the years, but some of her recent behavior has been concerning. Tammy has come a long way and accomplished a great deal since the beloved unscripted show premiered in 2020. The show centers around the incredible weight-loss journeys of 37-year-old Tammy and her 36-year-old sister, Amy Slaton, who once weighed a combined 1000-plus pounds. When the sisters stepped on industrial size scales during the show’s premiere episode, Amy weighed over 400 pounds, and Tammy weighed in at a stunning 608 pounds.
