Kelly Bundred weighed a whopping 190 kilograms at her heaviest in 2014, but managed to slim down to approximately 67 kgs by March 2015 after having weight loss surgery.
Having undergone gastric bypass surgery to achieve her dream body, she hanged herself because being thin made her feel worse, her husband claimed.
The mother-of-one, of Chesterton, Staffordshire, had battled with her weight since she was a child.
Her husband Gareth says she 'suffered most of her life', constantly obsessing about her size and developing post-natal depression after the birth of her daughter in 2003.
He was hopeful her weight loss procedure would improve her mental health, but it ended up making it worse.
After two unsuccessful suicide attempts, Mrs Burndred killed herself in April.
Her devastated husband found her unconscious downstairs but paramedics were unable to save her.
The Burndred family has set up Kelly's Legacy to raise awareness of mental health problems in their local area. They have also been placing personalised notes on bridges near their home to reach out to people considering taking their own lives.
