JenniferEccles I too think people should take responsibility for their weight and health but, believe me as a life-long dieter, it's not easy.
At 5.2 I struggle to stay under 10 stone, currently 9.6 and have to be mindful of what I eat, every day. I have to do it though as have a family history of Type 2, heart disease, stroke, hypertension, etc. Much of our general health is in the genes but figure that if I at least keep my weight in check that that will help to live my healthiest life as possible.
But as I said, it's not easy - you sound smug.
