Dottie Perkins, who weighed more than 42 stone (600lb) when she first appeared on My 600lb Life, looks unrecognisable after turning her life around.
The TLC reality star endured a number of tragedies throughout her life, forcing her into unhealthy eating habits and causing her weight to soar.
By the time she was 18, Dottie weighed more than 21 stone (300lb) and had been hospitalised because of her weight several times.
