I'm 13 st 10 and I feel it too. When I was doing the charity walk for Breast Cancer at the weekend I caught sight of myself in the reflection of a large pane of mirrored glass and was instantly disgusted by the heffer I saw staring back at me. I've turned into what I dreaded at 18, FAIR FAT AND FORTY(one) and I despise myself for it.
So take heart that someone is struggling as well as you are and is about to embark on yet another detox to kickstart a pre-holiday weight loss again.
