Tammy Slaton has lost over 400 pounds since embarking on her weight-loss journey, and the 1000-lb Sisters star has been seen in plenty of posts with family, friends, and fans. While her momentum ahead of 1000-lb Sisters season 6 is commendable, it wasn’t always smooth sailing. Tammy was notably more stubborn than her sister, Amy Slaton, when it came to losing weight. However, in 1000-lb Sisters season 3, Tammy was admitted to a rehab facility after a life-threatening health scare. There, she began making more significant progress toward her weight-loss goals.
