Many people associate eating disorders with young women and anorexia. But in 2002, 35-year-old Charlie Walduck weighed a staggering 45 stone. On the brink of suicide, Charlie knew something had to change.

Growing up in Barrow-on-Furness, painfully shy as a child and over-sensitive for as long as he can remember, Charlie Walduck was drawn to food as an escape. His childhood is mapped by memories of the food he ate - his mum's pies, selection boxes at Christmas, Easter eggs at Easter.

By 2003 and in his mid-thirties, Charlie was close to 50 stone. Every morning he'd phone his local cafe to deliver 2 or 3 full cooked English breakfasts direct to his door. As his weight grew, his self-esteem plummeted. He developed ulcers on his legs so painful he became unable to walk. Working at the time as a bingo caller in Manchester, the catalyst for change came when one day he was up on stage and the chair he was sitting on collapsed. The shame of that moment sent him to rock bottom. And it was at this time that his best friend took Charlie's life in her own hands by penning a letter to Fern Britton on This Morning and asking for help. With the nation watching and with the immeasurable support of the programme's GP Dr Chris Steele, Charlie began his weight loss quest, eventually losing 30 stone in less than two years.

Slimmer Charlie follows Charlie's weight loss journey in his own words, recalling with insight his struggles with food and the associated problems of low self-esteem, lack of confidence and shyness. Recalling vividly growing up in a working class family in the north of England, this is as much a memoir as a self-help guide.

Charlie is looking forward to answering your questions and giving advice on weight-loss.
