They think their tummies are wobbly, their breasts saggy and their bums huge. Yet, these four women stripped off and bared all.
Why? They all appear in the Channel 4 series How To Look Good Naked in which fashion stylist Gok Wan teaches women how to feel confident. Here, they tell MISHAAL KHAN how it changed their lives.
Lisa Mayall, 36, is a full-time mother who lives in Newbury, Berks, with her children Eva, eight, Alfie, six, and Joseph, two. She says:
Until I appeared in the programme, I had a really unhealthy body image. More than anything I hated my stomach, which bulged out at the top of my trousers.
It really got me down. My children lovingly call it "the doughnut" and I used to laugh about it - but deep down I was hurt and my confidence was low.
Confidence boost: Lisa Mayall
My self-esteem was already at rock bottom because a few weeks after I had Joseph, my partner left me for another woman. We'd been together for 13 years, and I thought it was a good relationship.
I was deeply in love with him and that probably explains why I put up with his mental abuse for so long. He always put me down and made me feel bad about myself.
I began to question why he left. I blamed myself for him leaving. I genuinely thought there might be something wrong with me - the way I looked, dressed or behaved.
Looking back, I never really took pride in my appearance. I never felt I deserved it. I just didn't see grooming as essential to being a woman - an opinion I've now changed, thanks to Gok.
I used to hide behind baggy, hippystyle clothes. I was never overweight - I weighed between eight and a half and nine stone, and wore a dress size ten - but I wasn't happy with my body shape.
My boobs sagged and my tummy was soft. I wanted to be more toned.
I finally reached breaking point two years after my partner left. I felt so miserable and told myself I couldn't carry on like this. I was tired of questioning myself.
I was still young, and had three children to look after. If I didn't look after myself, it wouldn't make me a good role model to them.
The TV programme couldn't have come at a better time. I'd watched the first series and applied to appear on the programme last summer. There were more than 6,000 applicants, so to be one of the final eight was exciting.
Gok is fantastic. He is an enormous character, but he is also very genuine. He helped me look beyond my insecurities and love myself again.
The first day I met him, I had to strip down to my underwear. Standing in my smalls in front of a mirror and an entire camera crew was intimidating. But I didn't consider backing down. I knew I had to take the leap if I wanted my life to change. Once I'd done it, I felt instantly lifted.
I gained so much confidence because I felt I was finally taking control of my life.
I saw my old underwear get eaten up by an industrial shredder, and I learnt how to go shopping for clothes that I felt good in.
The best experience for me was the nude image. The idea was I would be forced to confront the way I look and be convinced it was a body I could love.
I thought I'd be horrified for anyone to see the picture - but when Gok had finished with me, I was actually rather proud of it.
He has a skill to be able to convince women they should have confidence in themselves.
In the end, I was surprised at how much I enjoyed it. It was liberating and I didn't feel embarrassed stripping.
Since that epiphany, I've started wearing make-up and properly looking after my body. I've become much more adventurous - I'll wear heels, fitted jeans and skinny T-shirts. I'm feel more positive about life. I laugh more and can see the old Lisa returning. It would have been lovely to have shared this experience with someone special, but I haven't let that hold me back. I'm ready now for a healthy relationship
