BBC Headroom’s campaign tackling the psychological issues surrounding conditions such as anorexia, bulimia and obesity continues on screen with the story of one woman’s attempt to get to the root of her dysfunctional relationship with food, in Fix My Fat Head.

In addition to the campaign’s three documentaries, Headroom – the BBC’s health and well-being initiative – provides a raft of advice and support about eating disorders on the Headroom website, distributes information to doctor’s surgeries around the country and provides an action line to help those affected by the issues raised.

“Growing numbers of people in the UK are affected by eating disorders and obesity and we want to draw attention to some of the extraordinarily complex psychological concerns around those disorders,” explains Headroom campaign executive Nina Bell.

Thirty-six-year-old Hannah is a journalist with a razor-sharp wit and a lifelong problem: at 21-stone, she is clinically obese and has tried everything to lose weight. But nothing ever works and Hannah invariably ends up diving headfirst into a vat of carbohydrates and putting on more weight than she lost in the first place.

In Fix My Fat Head, Hannah takes an honest look at her relationship with food as she considers whether her overeating stems from psychological and emotional issues. Exploring hypnotism, overeaters support groups and cognitive-behavioural therapy, Fix My Fat Head is one woman’s attempt to finally understand the underlying causes of her condition.

“It’s not that I haven’t tried to lose weight,” says Hannah. “In fact I’ve been on every diet going. But I’ve never got to the bottom of my complicated relationship with food. I mean, I know what I should be doing to lose weight but why can’t I stick at it? Is the problem all in my head?”
