Hi my name is Irene, I am starting this 12 week programme to lose weight as my bmi is too high to allow me to have surgery on my knees. I have been given a six month window to lose weight; without much exercise as I find walking very painful. I have tried every diet going so I do know a lot about losing weight but sticking to it had always been my downfall. This time I have greater motivation as the pain I am suffering has become unmanageable. Any support would be gratefully received.
