     Glynis Davis:

     I first put on the pounds when I was in the family way and I couldn't lose them afterwards. Then I joined

a slimming club. My target was 140 pounds and I lost 30 pounds in six months. I felt great and people kept

saying how good I looked. But Christmas came and I started to slip back into my old eating habits. I told

myself I'd lose the weight at slimming classes in the New Year... but it didn't happen. Instead of losing the

pounds, I put them on. I'd lost will power and tried to believe that a few bags of fish and chips didn't make any

difference but the

scales don't lie.

     Roz Juma:

     To be honest, I never weigh myself any more. I've learnt to be happy with myself. It seemed to me that I

would feel sorry about every spoonful of tasty food that passed my lips. My idea is simple. You shouldn't be

too much thinking about food and dieting. Instead, you should get on with life and stop dreaming of a

super-thin body. This is obviously the size I'm meant to be and, most of all, I'm happy with it.

     Lesley Codwin:

     I was very happy about winning Young Slimmer of the Year. I'd look at the mirror unable to believe this

slim lady was me. That might have been my problem-perhaps from then on I didn't pay any attention to myself. Winning a national competition makes everything worse, though, because you feel the eyes of the world are

fixed upon you. I feel a complete failure because I've put on weight again.

     Ros Langfod:

     Before moving in with my husband Gavin, I'd always been about 110 pounds, but the pleasant housework

went straight to my waist and I put on 15 pounds in a year. Every so often I try to go on a diet... I'm really

good on a few days, then end up having the children's leftovers or eating happily chocolate-my weakness. I'd

like to be slim, but right now my duty is the children and home. I might take more exercise when my kids are

older.
