Last year I started training for a sporting event and as a result lost about 2 stone and completely changed my body shape. I never stopped eating but just carried on with my normal diet which is pretty healthy though it does include cakes and some crap, but I must burn a lot of calories. I am now 5ft 10 and weigh 9 stone 10 and have been for a year. I don't exercise as much now - about 3 times a week, but stay around this weight. I have very bony sternum and no boobs (they were always small), and my hip bones do stick out. I have stopped wearing vest tops because I think I look too thin in that area. Friends commented at the time I lost weighr that I was looking skinny but are used to it now. I would possibly look better half a stone heavier but for some reason the thought of putting on weight worries me.
