1000-lb Sisters star Tammy Slaton said she "could have easily" died if she had failed to lose weight.
The 36-year-old is grieving the death of her estranged husband Caleb Willingham, who died last week at just 40 years old. His health had "continued to get worse" after he reportedly gained 30lb (2.1 stone) while in a food rehabilitation centre.
Tammy and Caleb split just two months before his death following a whirlwind romance. It's thought Tammy called time on their relationship because Caleb "wasn't taking care of his health".
