One in five people have an eating disorder and of those, three in every five are compulsive eaters, according to the Institute of Psychiatry (IoP).
As reported by The Daily Mail, the IoP's guidelines define binge-eating as "eating an amount of food that is considered excessive ... by an individual ... associated with a feeling of loss of control over eating."
Most, although not all, compulsive eaters are obese, 60% are women and almost half of sufferers experience depression.
The Daily Mail was granted access to Overeaters Anonymous, where Annabel, a project manager, confessed the extent of her condition. "When I got home from work I would lock the door, draw the curtains, turn on the TV and eat," she said. "At the weekend I would spend all day walking from the sofa to the refrigerator and back. I wanted to be with food rather than people."
Annabel continued: "I was unhappy with myself, and my weight, but I couldn't stop. The unhappier I became, the more I buried my feelings with food. Coming here has helped me realise I don't have to do that."
Lisa, another compulsive eater, used to weight 25 stone. "People say, 'well, you're just fat, stop eating.' But it is an illness. The moment I eat something, I'm thinking about the next mouthful and I can't stop."
The 29-year-old property developer from West London told The Daily Mail about her last memorable binge: "It was a Saturday, after lunch, and I went to the Krispy Kreme doughnut shop at Harrods, planning to buy four doughnuts. But the guy behind the counter persuaded me it was better value to buy a dozen."
Lisa told how she ate six doughnuts and felt sick, so she then binged on a litre tub of ice cream in the hope it would make her feel better. It didn't, so she thought something savoury would and cooked two chicken kievs and a huge portion of ships. Then she finished the doughnuts, had another tub of ice cream and some chocolate.
By working with the subconscious, hypnotherapy helps clients understand the reasons behind their binge-eating. Instead of relying on will power to reduce eating, hypnotherapy helps overcome the compulsive eating triggers to help sufferers break free of the addiction.
