First, I thank the hon. Member for Blaenau Gwent (Nick Smith) for securing this debate on such an important topic. It is one of my personal passions, particularly while I have been in this job. It is evident from the contributions of so many colleagues, who made so many thoughtful points, that many share my passion for this area. I do not pretend to think that I can respond to every specific point that was raised, because it has been a varied and wide-ranging debate, which demonstrates Parliament’s appetite to get stuck into this topic. I will return to the powerful role that MPs have in increasing levels of physical activity if I have time towards the end of my remarks.
Society has changed a great deal, and that sits behind everything we have been debating this morning—why we have become more sedentary—and other Members have laid that out. I will not spend too much of my speech going over the evidence base, because it has been well covered by the hon. Gentleman and other Members, but the evidence base is well established for the problems that the level of physical inactivity in our nation is causing. I was pleased to hear Members talk not only about physical conditions, but mental health. I think dementia was also mentioned. There is an important evidence base for the fact that becoming more physically active can benefit people in a great many ways. One of my personal passions is how physical activity can impact on social isolation and exclusion; I will try and touch on that later. I will not reiterate what other Members have said on the statistics on how inactive we have become as a nation, because they are all on the record; I would prefer to use my time—I am conscious of leaving a little bit of time for the hon. Gentleman to wind up—by telling the House what the Government are doing.
I will say a few words about obesity. It is a slightly complex area, as I was saying to the hon. Gentleman just before we came into the Chamber. We are clear that
all the expert evidence suggests that while physical activity brings the important health benefits that we have been discussing—such things as stronger muscles and bones and improved cardiovascular health and metabolic health, as well as some of the psychological well-being aspects—tackling obesity is fundamentally about eating and drinking less. That is what will lead to significant weight loss. That is not to belittle the role of physical activity, but to emphasise its importance. Physical activity cannot just be seen through the narrow prism of its role in weight loss, because it is bigger and more important than that and goes to the heart of so many well-being and other social issues. I am keen that it is not cast only in the light of weight loss. We need to understand its role in tackling obesity, not least in encouraging active lifestyles in children from the very start and not building up problems for future generations, but it is a little more complex than that.
