Karen - Hi. Just over 2 yrs ago, my body fat was 40% and I was 10.5 stone. A bit hefty for me at 5ft 3in. So, I increased my activity - initially swimming and gymming. That started to have an effect within a few months. Then a Personal Trainer got me into running, and I found that accelerated my weight loss, and more importantly, my fat loss. I also bought Patrick Holford's book 'The Fat Burning Diet', which I found a bit extreme, but never the less adopted the main principles ie. balanced diet, lots of fruit, veg, seeds, nuts, wholefoods, the right type of fats, not too much caffeine/alcohol. Now my body fat is 23%, and I'm 9 stone. I agree with others that it is difficult not to get obsessed about it, and I do try not to. I tend to try and go by how tight/loose my clothes are, but can't resist the scales every now and again. And I still hate that sinking feeling you get when you have put any weight on. I had an injury-induced lay off from running of about 2 months, and was distraught to have put on 4 lb. Silly isn't it? I just have to remind myself what I've achieved, and how much fitter I am, and how nice it is to be in size 8/10 trousers - sod the odd lb or two!! (besides, that might be muscle I've put on??) NB
