My noble friend brings to mind the quote—I forget who it was by—saying that children never listen to their parents but have never failed to imitate them. There is a point about setting an example, which I agree with. I do not quite agree with the force of his opinion about how health professionals should speak to people suffering weight problems of that kind. These things can be genetic or epigenetic; there can be all sorts of causes. The most important thing is to get people on board with losing weight and motivate them to do so. We have lots of good understanding about how to do that, which is at the heart of the obesity strategy.
