Well, here I am, all 13st 7lbs of me and, having just gone through the first page or two of this site, I've had a reality check!
I now know that my aim of "losing a stone or two" is not going to be enough. My BMI is too high at 27.4 and I need to lose about 3st 4lbs to get to a moderately healthy weight.
So here goes - wish me luck!
