Obesity: Food and Diet

Simon Opher Excerpts

Monday 20th January 2025 Commons Chamber

[Dr Simon Opher (Stroud) (Lab)]

I beg to move,

That this House has considered the impact of food and diet on obesity.

I thank the Backbench Business Committee for allocating parliamentary time to this crucial issue. We were actually going to have this debate before Christmas, but we decided that before Christmas was not a good time to discuss obesity; we were then going to have it last week, but it was postponed. I am really grateful to colleagues across the House for supporting the debate.

Our country has an obesity crisis that is threatening the health and wellbeing of the whole nation. It is a cross-party issue: since 1990, rates of obesity have doubled. Two thirds of all adults in the UK are carrying excess weight, and a quarter of adults are classified as obese. The figures are even more worrying in children: 10% of children aged four, when they enter school, are obese; that figure rises to 22%—nearly one in four—in year 6. One problem with obesity is that, as many of us know, once someone becomes overweight, it is difficult to shift. That is why the most important age group to concentrate on is young people.

Obesity is now the single most important modifiable risk factor for the prevention of disease, and I will briefly go through its effects—as a doctor, I cannot resist. Around 4 million people in this country have type 2 diabetes, which is five times more likely in obesity. Type 2 diabetes almost doubles a person’s mortality rate, with 22,000 people with diabetes dying early every year. Ischaemic heart disease, the leading cause of death in the UK, is much more common in obesity, as is hypertension and osteoarthritis, which causes joint pain and reduced mobility. Something that a lot of people do not know is that 13 cancers are directly attributable to obesity—it is actually also the second commonest cause of cancer.

As a GP, there are other things I see quite regularly, such as reflux, varicose veins, infertility and even thrombosis, all of which diminish quality of life. The commonest cause of liver disease is now obesity. I will not go into the cost too much but, as we can imagine, obesity costs the country an absolute fortune: on average, four extra sick days a year; and, taking into account the cost to the NHS and so on, an estimated £98 billion a year, or 4% of GDP. The cost to the NHS is £19 billion a year.

What is the cause of obesity? From the evidence, it is clear that the main cause of obesity is diet—it is what we eat. The food system in this country is fundamentally broken. I welcomed the statement from the Secretary of State for Environment, Food and Rural Affairs, my right hon. Friend the Member for Streatham and Croydon North (Steve Reed) about sustainable food production: nutritious foods grown while restoring nature, and farms with good food production at its core, rewarded properly. There is a complicated relationship in food production, whereby farms mostly exist on Government subsidy with very small profit margins and then the supermarkets make profits out of what they sell. We need to look into that complicated relationship.

One problem is that unhealthy and ultra-processed foods—UPFs—that are high in fats, salt and sugar are often the easiest, cheapest and most convenient. Crucially, they make the most profit for the food industry. The other problem with these types of food is that they are addictive—salty, fatty foods are addictive. Another problem, revealed by the Food Foundation, is that healthy foods, calorie for calorie, are twice as expensive as less healthy foods. So there are a lot of issues there to unpick.

Inequalities and deprivation are very, very strong causes of obesity, with less well-off people being twice as likely to be overweight. Therefore, one strategy has to be to increase the living wage, reduce child poverty, improve health and social services, and invest in education —all of which the Government are doing.

On pregnancy, obesity actually begins in the womb—it does not even begin when we are born. In one fascinating experiment, one group of pregnant women were fed a lot of carrots and another group did not have any carrots. The children of the women who ate carrots loved carrots, so a memory is made in utero. It is therefore really important that pregnant women have a very healthy diet, as this is a risk factor for obesity in young people. Another is formula feed. Breastfeeding protects against obesity, but formula feeds do not. Follow-on feeds, hungry baby feeds, are just normal milk packed full of calories, so they tend to increase obesity. That is perhaps something we need to discuss, too.

[Wera Hobhouse (Bath) (LD)]

I am the chair of the eating disorders all-party parliamentary group. To make any progress, we have to understand that eating disorders are highly stigmatised. Many people with obesity also have an eating disorder. To make real progress, is not the first thing to take the stigma away from obesity and get to the people who really want to improve their lives?

[Dr Opher]

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.

[Peter Swallow (Bracknell) (Lab)]

Does my hon. Friend agree that it is important, when there is such a strong correlation between child poverty and child obesity, that we tackle not only the food systems leading to poor health outcomes, but the price of food? We must see those two challenges in lockstep and work to address both the quality of food and the cost.

[Dr Opher]

Absolutely. One of the main pitfalls we must avoid is that there is no point in making cheap food more expensive. That will make people poorer. We need to be much more creative than that.

[Mr Tanmanjeet Singh Dhesi (Slough) (Lab)]

I thank my hon. Friend for securing the debate and for allowing me to intervene. I commend the Government’s new policy of free breakfast clubs for all primary school children, but does he agree that we should not miss the opportunity to ensure that that meal is wholesome and nutritious so that all our kids can get off to the best possible start?

[Dr Opher]

Yes, I could not agree more. As I said in the debate on education, we should be careful about the food industry sponsoring school breakfasts. As I pointed out, there is no such thing as a free breakfast. Companies often make unhealthy and addictive food and get young people addicted to it, so we must be cautious.

I wanted a recipe to solve this crisis and what I am suggesting comes from evidence from Nesta and the House of Lords Select Committee. It should be mandatory that all stores report on the food healthiness of their sales. We need a fully independent Food Standards Agency. We should have a ban on advertising junk food, as has already been proposed, and there should be a watershed for children—that is incredibly important. As is planned in Scotland and Wales, there should be a ban on price promotions, particularly for unhealthy foods, ultra-processed foods and takeaways. We also need to put a lot more resource into breastfeeding and diet in pregnancies—remember the carrots—and we must regulate formula feeds.

One measure, which has worked with the drinks industry in reducing sugar, is a reformulation tax on foods that are high in sugar and salt. Supermarkets and food companies would reformulate their foods to avoid the tax, thereby making them healthier. My hon. Friend the Member for Slough (Mr Dhesi) mentioned breakfast clubs. There is a lot of evidence that free school meals and breakfast clubs reduce obesity. Where free school meals have been introduced in London, childhood obesity has been reduced by 11%. That is because the food is healthy and a healthy hot meal is really important, rather than high-calorie snacks, which are what a lot of packed lunches consist of. If we cannot have free school meals, because of financial problems, we should have auto-enrolment so that children who should be on free school meals actually get enrolled. That would benefit schools, too.

We must have mandatory front-of-packet labelling. I have never met a parent who does not want to buy healthy food for their children. The trouble is that they pick up a packet of cereal and it says, “High in iron and filled with vitamins,” and think it must be healthy. Nothing could be further from the truth, so we must have accurate labelling. Healthy school foods should be sourced locally. In Stroud, I have been working closely with local primary schools to encourage them to eat fresh, locally grown, highly nutritious food. I think the Government’s target is to procure at least 50% of food in schools from local sources.

Then there is the famous hospital food. I was recently in hospital with a relative, and I can tell the House that hospital food is not healthy. We had white-bread sandwiches and some crisps—that was our healthy snack. We must introduce healthy foods in hospitals.

Takeaways are another big barrier to healthy eating—there was a massive explosion in their use during the covid pandemic—and we need to include them in any regulation. As I have said, in Scotland and Wales a ban on takeaway price promotions has been proposed. On average, those in deprived areas order more takeaways than those in non-deprived areas. We certainly must not let takeaway outlets open near schools—that is a planning must.

I would also caution against the treatment of the obesity crisis with injections of drugs such as Ozempic, which could well turn out to be dangerous.

[Jim Shannon (Strangford) (DUP)]

According to today’s press, there is clear evidence of that. Apparently, 400 people across the United Kingdom who took Ozempic experienced poor health as a result. It is not for everyone, and the sooner that people know that, the better.

[Dr Opher]

The hon. Gentleman’s intervention reminds me of the GP I took over from—an old chap; very wise—who said, “Always be a few years out of date, Simon, because we never know what these new drugs are going to cause.” I think that is good advice—not that I am suggesting that doctors are out of date, of course.

Are we proposing the creation of a nanny state? That is the great fear of many people when they are confronted by controls of this kind, but let us look at what happened with the ban on smoking inside pubs. People—particularly in Ireland, but also in England—were saying, “This is crazy; it is never going to work”, but it worked fantastically well. We need to be aware of the vested interests of food companies, and we need to take radical steps.

[Max Wilkinson (Cheltenham) (LD)]

I thank my Gloucestershire neighbour for giving way. He mentioned the nanny state. As a Liberal, I believe in freedom, but there are two sides to it: freedom from and freedom to. Should not freedom from some of those representing the big, powerful vested interests in the food companies, who are not interested in our health, be at the centre of this debate?

[Dr Opher]

I entirely agree. I think that this Parliament could do to obesity what the Government who were in power between 1997 and 2010 did to smoking: we could drastically reduce it. For the sake of our children and our older adults, I urge everyone to accept that we need to act now, and we need to act radically.

--- Later in debate ---

[Dr Opher]

I thank the Minister and all who have spoken because this has been a genuinely interesting debate about an essential topic. I would just like to say in summary that the hon. Member for Chester South and Eddisbury (Aphra Brandreth) needs to go into the supermarket when she is really busy and pick up a tasty healthy snack. If the Government can get people doing that, it will be fantastic. I say to the Minister that the House is behind him being radical; it is not the time for non-intervention.

I thank all who have contributed. I missed supper and am starving, so I am going to go and have a healthy snack.

[Hon. Members]

Hear, hear!

Question put and agreed to.

Resolved,

That this House has considered the impact of food and diet on obesity.
