I absolutely agree with that. We must treat people in a fair and compassionate way. We must point that out to them, as medical professionals, and help them to get better. I agree with the hon. Lady about stigma. On obesity strategies, since 1990, we have had 700 separate policies to tackle obesity, yet it has doubled. Clearly, we are doing something wrong. Having looked at the evidence, it is clear that voluntary targets do not work. Voluntary targets for the food industry and relying on individual agency—giving us choice in what we eat—cannot reduce obesity. The food industry, of course, has a vested interest in making money. While education and exercise are really good, there is not much evidence to suggest that they reduce obesity. It is all about food. There has been a lot of research. Nesta, the Obesity Health Alliance and the House of Lords Food, Diet and Obesity Committee have done multiple reports on obesity, and it is clear that we can halve it. All we need to do is reduce everyone’s calorie intake by 200 calories a day. That is the difference between McDonald’s large fries and standard fries—other fries are available—so it is not a massive thing, but we all have to do it. As always with public health, small drops in what we take can have a massive effect on the population.
