hi. I am a typical yo yo dieter. I started again last Saturday on my own version of slimfast. I weighed 20st 9.6 last week and I have a hell of a long way to go. But I'm determined this time. My brother has a brain tumour and set me a task in his will of get down to healthy BMi or run a marathon. I am not a runner. Never will be. So let's try for the bmi.
