Major study reveals disappointing reality of what happens to the body a year after coming off Ozempic
People who take weight-loss jabs to shift some pounds pile it all back on within 10 months of stopping, a study found.
Scientists at Oxford University discovered the effects of GLP-1 drugs like Wegovy are short-lived if patients do not maintain a healthy lifestyle afterwards.
Even those taking newer, more powerful jabs drugs like Mounjaro put their weight back on once treatment was removed.
'These drugs are very effective at helping you lose weight, but when you stop them, weight regain is much faster than [after stopping] diets,' said researcher Professor Susan Jebb.
'Is it going to be worth the NHS investing in these drugs if they only have them for a short time and then they pile all the weight back on, or does the NHS have to accept that these are going to be long term therapies?
'Either people really have to accept this as a treatment for life, you're going to have to keep going forever, or we in science need to think really, really hard, how to support people when they stop the drug.'
While the study didn't explain why people pile their weight back on so fast, Professor Jebb speculated it could be because diets are hard. No self restraint is required when taking the drugs, so people don't have 'behavioural strategies in place' when they stop taking them.
The research, presented at the European Congress on Obesity in Malaga, Spain, looked at 6,370 adults in 11 studies.
The findings raise issues for the government, which plans to roll out NHS-funded weight-loss jabs far and wide over the next few years.
Healthcare funding watchdog NICE currently advises that people shouldn't be on the injections for more than two years.
Tam Fry, chairman of the National Obesity Forum, said: 'It shouldn't surprise anyone if people regain weight having used GLP-1 drugs without seriously attempting to improve their lifestyle. Using GLP-1s is not the quick-fix which many users believe it to be.'
Jane Ogden, professor of health psychology at Surrey University, added: 'There's no point just throwing people back out into the world of their own lives [after they stop taking jabs].
'They're going to need psychological counselling, behaviour change, nutritional support from that moment on to help them sustain healthier behaviour and keep the weight off.'

Several US Jolly rancher sweets unsafe to eat, FSA says
A number of products from a brand of US sweets are "unsafe to eat" and contain ingredients which could increase the risk of cancer and cause damage to DNA, the Food Standards Agency (FSA) has businesses and consumers are being urged to stop buying and selling the Jolly Ranchers products, owned by US company FSA says they contain chemical compounds - mineral oil aromatic hydrocarbons (MOAH) and mineral oil saturated hydrocarbons (MOSH) - which are "not compliant with UK laws".The products pose a safety risk if consumed regularly over time but there is "no immediate cause for concern, as [the] food safety risk is low", the agency adds. In a food alert published on Wednesday evening, the FSA said: "MOAH can cause damage to DNA and has the potential to increase the risk of cancer, particularly if consumed in high quantities over a prolonged period of time."MOAH is a genotoxic carcinogen, therefore no exposure is without risk to human health."MOAH and MOSH are used in confectionary to prevent stickiness and create a glossy to the agency, The Hershey Company has been working with the UK government body to remove the affected Jolly Rancher products from the UK market since 2024, but some businesses in Britain have continued to import the affected products are: Jolly Rancher Hard Candy, Jolly Rancher 'Misfits' Gummies, Jolly Rancher Hard Candy Fruity 2 in 1, and Jolly Ranchers Berry food agency is advising people who have any of the listed products to not eat them and dispose of them at home.

Britain morphing into ‘National Health State', says think tank
Britain is turning into a 'National Health State', a think tank has said after the Chancellor gave the NHS a major funding boost in her spending review. The health service was the big winner of Wednesday's spending review, receiving an extra £29 billion per year for day-to-day spending and more cash for capital investment. Overnight, the Resolution Foundation said Rachel Reeves's announcements had followed a recent trend that saw increases for the NHS come at the expense of other public services. Ruth Curtice, chief executive of the Resolution Foundation, said: 'Health accounted for 90% of the extra public service spending, continuing a trend that is seeing the British state morph into a National Health State, with half of public service spending set to be on health by the end of the decade.' Defence was another of Wednesday's winners, Ms Curtice said, receiving a significant increase in capital spending while other departments saw an overall £3.6 billion real-terms cut in investment. The Institute for Fiscal Studies (IFS) made similar arguments about 'substantial' investment in the NHS and defence coming at the expense of other departments, although the think tank's director Paul Johnson warned the money may not be enough. He said: 'Aiming to get back to meeting the NHS 18-week target for hospital waiting times within this Parliament is enormously ambitious – an NHS funding settlement below the long-run average might not measure up. 'And on defence, it's entirely possible that an increase in the Nato spending target will mean that maintaining defence spending at 2.6% of GDP no longer cuts the mustard.' Ms Curtice added that low and middle-income families had also done well out of the spending review 'after two rounds of painful tax rises and welfare cuts', with the poorest fifth of families benefiting from an average of £1,700 in extra spending on schools, hospitals and the police. She warned that, without economic growth, another round of tax rises was likely to come in the autumn as the Chancellor seeks to balance the books. She said: 'The extra money in this spending review has already been accounted for in the last forecast. 'But a weaker economic outlook and the unfunded changes to winter fuel payments mean the Chancellor will likely need to look again at tax rises in the autumn.' Speaking after delivering her spending review, Ms Reeves insisted she would not have to raise taxes to cover her spending review. She told GB News: 'Every penny of this is funded through the tax increases and the changes to the fiscal rules that we set out last autumn.'

UK consumers urged not to buy ‘unsafe' American sweets amid cancer concerns
UK consumers are being urged not to buy a brand of 'unsafe' sweets which could increase the risk of cancer, the Food Standards Agency (FSA) has said. Candies from the Jolly Rancher brand contain mineral oils, a food additive which can pose health risks if consumed regularly over a sustained period of time, the agency said. The chemical compounds in the products: mineral oil aromatic hydrocarbons (Moah); and mineral oil saturated hydrocarbons, (Mosh); are used in confectionary to prevent stickiness and create a glossy appearance, but do not comply with UK law. US producer, Hershey, which owns the brand, has been working with the FSA to remove all Jolly Rancher products from the UK market since 2024 – but some businesses in Britain continue to import their products, the agency added. The affected products include the Jolly Rancher Hard Candy, 'Misfits' Gummies, Hard Candy Fruity 2 in 1, and Berry Gummies, the FSA said. A food alert published by the FSA on Wednesday said: 'Consumption of the affected sweets is of toxicological concern, especially in younger age groups and where consumers eat a lot of the products or eat them regularly. 'Moah can cause damage to DNA and has the potential to increase the risk of cancer, particularly if consumed in high quantities over a prolonged period of time. Moah is a genotoxic carcinogen, therefore no exposure is without risk to human health.' It added: 'If you have bought any of the above products, do not eat them. 'Instead, dispose of them at home. If you are concerned, notify your Trading Standards department or environmental health department in the local authority you purchased it. 'For consumers, don't buy them, and if you've eaten these products, there should be no immediate cause for concern, as food safety risk is low, but don't eat any more.' The agency has also urged UK retailers and food businesses to cease all imports and sales of the candy brand, and asked enforcement authorities to ensure the products are removed from the shelves. The FSA said: 'Food businesses who import these products are advised to discontinue import and distribution of products. 'Food businesses selling these products in the UK are advised to immediately stop sales, undertake product withdrawals and where there have been retail sales, to undertake product recalls. 'The Hershey Company, who is the brand owner, has taken action to remove these products from the UK market. 'We are asking enforcement authorities to make immediate contact with businesses who may have been supplied with or received the affected products, and to take action to ensure that the non-compliant and potentially unsafe products are withdrawn from the market and where sold at retail, recalled. 'We are also asking the local authorities to inform the FSA of product recall and withdrawal actions.'
