I just wonder about individual responsibility. If your clothes are beginning to feel a bit tight, if moving around is becoming a little more effortful, if walking to the bus stop (or wherever) is slightly more of a struggle, isn't that a warning sign? Why wait until you are 2 stone, 3 stone, 4 stone… overweight before you think you should do something about it (for your own well-being) when it is going to be so much more difficult and long-term to do so? Great dollops of overweight don't go on (or off) overnight – it's a gradual process. Why not nip it in the bud rather than blame the food industry, the weight loss industry or, perhaps, Vladimir Putin?
