So, I've decided to do weight watchers diet during the week, relax at weekends and eat a bit of what I fancy and walk briskly for about an hour at least three times a week (I can just about have a conversation but not sing when I'm walking, so reasonably brisk but not over quick). I'm not over weight (5'7'' and weigh 10stone 9 lbs) but weight has been creeping up on me since I stopped obsesively walking around with a buggy containing small children and started working more. I would like to lose half a stone or nine pounds at the most. So, will I A) lose half a stone doing what I'm doing? B) Get fitter? C) Do something about my flabby thighs and muffin tops? and D) How long will it take?
