The number of obese people worldwide has surpassed one billion, according to global analysis.
Research published by The Lancet journal shows 879 million adults and 159 million children were obese in 2022 – the most recent year included in the analysis.
In the UK, around 16.8 million people are living with obesity – which includes eight million women, 7.4 million men, 760,000 boys and 590,000 girls, according to the study.
The study was conducted by the NCD Risk Factor Collaboration – a network of health scientists around the world – in collaboration with the World Health Organisation (WHO).
The data shows that globally, obesity rates among children and adolescents quadrupled from 1990 to 2022, while rates among adults more than doubled.
Meanwhile, the study also revealed that the rates of children and adolescents who were underweight dropped over the same period and more than halved among adults worldwide.
This makes obesity the most common form of malnutrition in many countries, the researchers said.

Senior author Professor Majid Ezzati, of Imperial College London, said: “It is very concerning that the epidemic of obesity that was evident among adults in much of the world in 1990 is now mirrored in school-aged children and adolescents.
“At the same time, hundreds of millions are still affected by undernutrition, particularly in some of the poorest parts of the world.

“To successfully tackle both forms of malnutrition it is vital we significantly improve the availability and affordability of healthy, nutritious foods.”
In the UK, the obesity rate among adults increased from 13.8% in 1990 to 28.3% in 2022 for women and 10.7% to 26.9% in 2022 for men.
For children and adolescents, the rate jumped from 4.7% in 1990 to 10.1% in 2022 for girls and 4.3% to 12.4% in 2022 for boys.
Meanwhile globally, the obesity rate more than doubled in women, nearly tripled in men, and more than quadrupled in girls and boys, from 1990 to 2022.
Places with the highest prevalence of obesity include Tonga, American Samoa, Polynesia and Micronesia, Cook Islands and Niue.
Data also showed that globally, as of 2022, around 532 million people are underweight, including 183 million women, 164 million men, 77 million girls and 108 million boys.
And in the UK, around 981,000 people are underweight, which includes 430,000 women, 360,000 men, 61,000 girls and 130,000 boys.
How was the study carried out?
The researchers used body mass index (BMI), which is calculated using a person’s weight and height, to understand how obesity and underweight levels have changed worldwide over three decades.
The team gathered data from more than 3,000 population studies with 222 million people.
The researchers said that although BMI is an imperfect measure for determining the extent of body fat, it is widely recorded in population-based surveys.
Dr Tedros Adhanom Ghebreyesus, director general of the WHO, said: “This new study highlights the importance of preventing and managing obesity from early life to adulthood, through diet, physical activity and adequate care, as needed.
“Getting back on track to meet the global targets for curbing obesity will take the work of governments and communities, supported by evidence-based policies from WHO and national public health agencies.
“Importantly, it requires the co-operation of the private sector, which must be accountable for the health impacts of their products.”
Figures ‘as alarming to parents as they are to NHS’
Professor Simon Kenny, NHS England’s national clinical director for children and young people, said: “These figures will be as alarming to parents as they are to the NHS.
“Obesity affects every human organ system, and so at a young age can have a major impact on a child’s life, increasing their risk of type 2 diabetes, cancer, mental health issues and many other illnesses, which can lead to shorter and unhappier lives.
“The NHS is committed to helping as many young people and families affected by extreme weight issues as possible through our new network of 30 specialist clinics, which offer tailored packages of physical, psychological and social support – but the NHS cannot solve this issue alone, and continued joined-up action by industry and wider society is needed if we are to avoid a ticking health timebomb for the future.”
The family of a grooming victim say they are “angry” and “heartbroken” that prosecutors didn’t see a video of her police interview during their investigations.
Jodie Sheeran, then 15, was allegedly taken to a hotel and raped in November 2004.
She’s believed to have been groomed by young men of Pakistani heritage for a year beforehand. Jodie’s son, Jayden, was born nine months later.
A man was charged, but the case was dropped a day before the trial was meant to start in 2005.
Her father, David, said they were told it was because Jodie had a “reckless lifestyle” and was “an unreliable witness”, but that they never received a formal reason.
Jodie died in November 2022 from an alcohol-related death.
It’s now emerged the Crown Prosecution Service (CPS) didn’t view the video of Jodie’s police interview as it “was not shared with us” and they didn’t know at the time that it still existed.
Instead, they only had a transcript of what she told officers.
It’s unclear exactly why this happened, but Staffordshire Police said the footage was available in 2019, when the CPS and police reviewed the case, and in 2023, when the investigation was opened again.

“I don’t know if I’ve been misled [or] it was an accident,” Jodie’s mother, Angela, told Sky News’ Sarah-Jane Mee.
“To suddenly say evidence has been there all along – and I’ve got every single letter, every email to tell me they haven’t got the evidence any more… and then it’s emerged Staffordshire Police did have the evidence after all – it was shocking really.”
The CPS watched the video last month and said the transcript is an accurate representation of what Jodie says on the tape.
However, it hasn’t changed their view that there’s no realistic prospect of conviction – and won’t be taking any further action.

Jodie’s father told Sky News he believes it shows the police and CPS “didn’t know what one another were doing – and it makes you so angry”.
“I feel like they’ve gotten away with it,” added Jodie’s son Jayden. “It’s years on now – I’m grateful they’ve found the evidence but what are they doing about it?”
‘I’ll keep fighting until I get justice’
Angela said it shows that other families in a similar situation shouldn’t “take no for an answer” from police or the CPS.
“Since losing a child, nothing else matters, so I’m not going anywhere,” she said.
“So I will keep fighting and fighting and fighting until I get justice for Jodie – and hopefully justice for probably thousands of other victims out there as well.”

A Staffordshire Police spokesperson said their thoughts remain with Jodie’s family and that a “significant amount of work has been undertaken reviewing this case several times”.
They said the interview video was “available to the Senior Investigating Officers in 2019 and 2023” and a “comprehensive contemporaneous written record” of it was given to the CPS on both occasions.
The statement added: “In August 2025, a copy of the recording was provided to the CPS who conducted due diligence to ensure the contemporaneous written record of Jodie’s ABE interview, that they reviewed in 2019 and 2023, was an accurate account of the video recording. They have confirmed this is the case.”
Police said the case had beensubmittedfor a further evidential review.
“Should any new evidence come to light, it will be referred to the CPS for their consideration,” the spokesperson added.
The CPS said: “We carried out reviews of our decision-making in this case in 2019 and 2023 using records provided by Staffordshire Police – both these reviews found that there was not enough evidence to charge the suspect with rape.
“While we requested all available records, Jodie’s video interview from 2005 was not shared with us, we were not informed that it had been retained, and it was only made available to our prosecutors recently after further requests.
“Having cross-referenced the video with detailed accounts of it previously available to us, we have determined that the conclusions we reached in our previous reviews still stand.”

Children sexually abusing other children has become a “crisis” in the UK, experts have told Sky News.
This report contains details you may find distressing.
The National Association for People Abused in Childhood (NAPAC) says there has been a pronounced rise in child-on-child abuse – and data for group-based offending shows it is now more prevalent than incidents involving grooming gangs.
The “shocking” statistics show there has been a “fundamental shift” in offending, NAPAC chief executive Gabrielle Shaw told Sky News.
Latest child sexual abuse and exploitation crime figures from the National Police Chiefs’ Council (NPCC) for England and Wales show that, where age was recorded, 52% of all perpetrators were between the ages of 10-17.

Some 41% of these relate to indecent images of children.
Most of these nude images are taken by teenagers of themselves before they are shared with a partner as part of “experimental” behaviour.
But at the other end of the offending scale, 17% of sexual crimes that are committed against children by other children are rape offences.
Richard Fewkes, director of NPCC’s child sexual exploitation taskforce, warns that consensual exchanging of intimate images can end up in coercion and blackmail, with easy access to violent pornography partly behind this disturbing trend in children abusing children.
“For a generation of boys, in particular, then very often they see that as normal behaviour,” he told Sky News. “They act it out, with girls.”
Teenagers sharing indecent images of each other may be recorded as crimes due to the legal age of consent, according to Richard Fewkes.
Inside the call centre on the frontline
Warning: This section contains references to child sexual abuse
There’s a shrill ring as the first call of the day comes in. “You’re through to someone you can talk to.”
We’ve been given exclusive access to NAPAC’s helpline in Stockport, where call handlers speak to victims who have suffered all types of abuse.
The man who has called the helpline was so badly beaten as a child by his father that he was left with broken bones.
The victim is now having to care for his elderly father, triggering painful memories.
“He just wanted that safe space,” says call handler Claire Tong.
“He said, ‘Thank god there’s people like you that I can talk to’.”
NAPAC’s support service hears from around 10,000 victims every year – and the organisation also works with police in responding to group-based sexual offending.
Through our day at the helpline, we get a grim snapshot into the lives of ordinary people across the UK who have suffered unimaginable pain.
Children ritually abused to ‘raise demon’
Sam Booth has worked at NAPAC for a decade, first as a volunteer and now as a supervisor.
She shows me the themes of last week’s calls written on a whiteboard and one stands out – ritual abuse.
“Satanic ritual abuse is abuse by a group of people,” Sam says.
“They have robes on with hoods. They could be a child or a teenager, they could be ritually, sexually abused ….to raise some kind of demon.”
Sam says multiple people have called, triggered by the smell of soil. As children, they had been buried to the point of death before being revived.
Victims can be signposted to other services, for example if they want to pursue legal action or therapy.
Support can mean difference between life and death
Among those to have been helped by NAPAC is Sadie, who was sexually abused by her biological father when she was a young child.
Sadie, not her real name, says her childhood memories are “the constant feeling of being dissociated from your body, always having stomach aches, feeling unclean”.
Sadie’s email to NAPAC, fully disclosing the abuse for the first time, was the crucial step towards getting direct support.
For some victims, their call could be the difference between life and death.
The rise in young people seeking help
Exclusive data shared with Sky News shows that in 2014, NAPAC received 358 calls in which callers volunteered their age.
16 of these callers were between the ages of 19 and 24 (4.4%).
Over the next decade the percentage doubled.
In 2024 there were 1,487 calls in which callers volunteered their age.
130 of these callers were aged 19-24 (8.8%).
More than half of callers of all ages say they feel anxious or experience anxiety.
Meanwhile, more than a third of callers say they feel isolated.
Holly Aisbett, who has worked for NAPAC for three years, says a conversation that stands out to her was with a suicidal woman calling from a bridge.
“We were probably on the phone for about an hour; she did eventually tell us her location,” says Holly.
“We reported it to the police, we don’t often do that, but obviously when things escalate, we do have a duty of care.”
All the NAPAC staff we spoke to admit to being impacted by challenging calls every day. But they continue to handle them with empathy.
“You get a really good feeling when you get a caller talking to you about something they’ve never told anyone,” says Sam.
“You feel privileged that they’re able to talk to you.”
Mr Fewkes said there is no easy solution to the crisis of children abusing children, but he believes better education for parents and young people is a crucial step in the right direction.
A Home Office spokesperson said: “We are taking forward a wide range of actions to help prevent child sexual abuse, bring more offenders to justice, and improve the support available to victims and survivors.
“A review is currently underway to look at how best to support school staff in handling cases of child sexual abuse. This sits alongside increased funding for the Lucy Faithfull Foundation, which works to prevent harmful sexual behaviour among children and young people.”

Sir Ed Davey will call on US experts fleeing an “anti-science agenda” to come to the UK, and pledge to make curing cancer a “top priority”.
The Liberal Democrat leader will use his keynote speech at the party’s annual conference in Bournemouth today to call for a dedicated fellowship scheme to attract American scientists.
Sir Ed is expected to warn that “what’s happening on the other side of the Atlantic” is the “biggest threat to the fight against cancer”.
“The US is by far the world’s biggest funder of cancer research – mostly through its National Cancer Institute,” the leader will say.
“But since Donald Trump returned to the White House, he has cancelled hundreds of grants for cancer research projects.
“He’s slashing billions of dollars from the National Cancer Institute’s budget.”
Sir Ed will appeal to scientists who have had projects cancelled or funding cut to “come here and finish it in the UK”.
He believes a dedicated scheme should be established to allow them to move to work at British research institutions, without having to pay large visa fees.
Sir Ed has is the only English party leader to explicitly criticise Mr Trump, and refused an invite to the state banquet with the King at Windsor Castle as part of the US president’s state visit last week.

Davey refuses to rule out deal with Starmer
‘Cast-iron guarantee’ for cancer patients
Sir Ed will also use his speech to pledge to boost healthcare and cancer research more widely.
He is expected to tell party members: “The UK should step up and say: if Trump won’t back this research, we will.
“We’ll boost funding for cancer research in the UK. We’ll rebuild a National Cancer Research Institute, after it was closed under the Conservatives, to coordinate research and drive it forward.
“We’ll pass a Cancer Survival Research Act to ensure funding for research into the deadliest cancers.”
He will announce a “cast-iron guarantee” that each patient in the UK diagnosed with cancer will start treatment within two months.
Sir Ed will also accuse Reform members of supporting the Trump administration’s move to cut millions of pounds of research into mRNA vaccines, based on “totally false conspiracy theories”.
He will say they members “enthusiastically applauded” the decision at the party’s conference earlier this month.
It follows the Liberal Democrat leader refusing to rule out making a deal with Labour after the next general election to help keep Reform out of government.

Can Davey stop Farage getting into No 10?
Across the conference, Sir Ed has also:
Accused Elon Musk of being a “criminal [for] allowing online harm to children” on his social media platform X, insisting he’s not concerned about being sued by the billionaire for saying so despite him not being charged;
Suggested the Lib Dems could win “way more” than 100 seats at the next general election;
And accused the BBC of scrutinising Reform less than other political parties.
The Liberal Democrats have already used the conference to announce plans for a windfall tax on big banks to help homeowners install solar panels and insulation, and propose cigarette-style health warnings on social media apps to protect children.
They also want to introduce a law to ban ministers from lobbying on behalf of foreign leaders.
