'Golden age' of weight loss drugs could trigger surge in number of Britons who live to 100, experts say

Daily Mail​14-05-2025
Weight-loss jabs could usher in a 'golden age' of medicine that could boost the number of Britons living a century, experts say.
The injections, which include the likes of Mounjaro and Wegovy, were originally developed to combat obesity.
But they have been found to have a range of other benefits including delaying diseases associated with ageing and slash the risk of heart attacks in half.
Experts have discovered the drugs, technically called GLP-1 agonists, target the 'underlying biology' of chronic illness meaning they could be given to millions of more patients even if they are a healthy weight.
Doctors have said that the jabs are the start of a new 'golden age' of medicine.
One trial–presented at the European Congress on Obesity in Malaga involving 17,000 patients-found the medications halved deaths from strokes and heart attacks.
Experts have now suggested that up to half of Britons could benefit from the jabs to 'live longer in good health.'
Professor Jason Halford, from the European Association of Obesity, told The Times: 'It is clear that the earlier people start on weight loss drugs, the better.
Currently the drugs are being rationed on the NHS, being given to just 50,000 people but now the Government is being urged to expand access.
Professor Halford added: 'If the Government and the NHS are serious about prevention they need to reconsider their position on the speed of roll out of these drugs.'
It was also revealed at the conference that another 150 similar drugs are now being developed by pharmaceutical firms.
Professor John Deanfield, a cardiologist at University College London, said that this is 'extraordinary' and a 'scenario we have never seen in medicine before.'
'These drugs do remarkable things to improve many diseases,' he said.
'They have shown benefits on heart disease, liver disease, kidney disease, cancer, mood and mental health.
One of the latest breakthroughs is a pill that mimics the effect of a gastric bypass which has been touted as the latest weight loss miracle.
Some experts say it may even be more effective than fat jabs in the long term.
The capsules produce a temporary coating in the gut that prevents food from being absorbed, forcing it into the lower intestine and triggering hormones that make you feel full.
Its manufacturers say it may have advantages over weight-loss injections such as Ozempic and Mounjaro, including having fewer side effects and being easier to take.
It is also far safer and less invasive than actual gastric bypass surgery.
Rahul Dhanda, chief executive of Syntis Bio, makers of the pill, said: 'The problem is [fat jabs] are not very tolerable and patients want to come off them.
'You want to have a long-term maintenance therapy, and an oral pill is the rational choice because it's simple, tolerable and safe.
'What we're seeing now is patients and clinics being more focused on having something safe and sustainable to keep on a manageable, sustainable weight-loss path.
'I anticipate the side effects to be minimal to none, and we haven't seen any yet in human tests. That is because it doesn't enter the bloodstream like injections do.
'It's a mechanical molecule, so it's like we're inserting a stent, as opposed to a drug that is acting with the target, and also off the target.'
By binding to the mucous membrane lining of the duodenum - the top of the intestine near the stomach - the pills create a barrier that stops calories being absorbed.
It forces food directly into the lower part of the digestive system, the pills set off a 'cascade' of hormones including GLP-1, the same chemical mimicked by semaglutide jab Wegovy.
It also causes the body to stop producing ghrelin, which makes you feel hungry, and start producing leptin, which makes you feel satisfied.
The person taking the pill feels full more quickly and stops eating.
The coating created by the pill sheds naturally after about 24 hours, leaving no trace.
The effect is similar to gastric bypass, in which surgeons make the stomach smaller and shorten the small intestine, changing how the body absorbs food and leaving people feeling fuller after eating less.
In rats, the drug caused the animals to lose 1 per cent of their bodyweight per week while preserving 100 per cent of their lean muscle mass.
Trials in humans have not studied weight loss but found the pills cause no harmful side effects.
If they prove effective in further trials, the pills could help patients maintain a healthy weight after intensive weight-loss with jabs, or replace the injections entirely.
Dr Louis Aronne of Weill Cornell Medicine in New York City told the conference that a 'golden age' of treatment had begun with these new drugs.
The Times reported he was pushing for health providers, including the NHS, to 'roll them out at scale', adding: 'I think use of drugs like this will prevent the need for many other medications, procedures, and surgeries.

'I thought snoring was a blocked nose - it was sign of skull-eroding disease'

Claire Barbery, 51, began snoring at night after experiencing a continuous blockage in one side of her nose - and almost cancelled her hospital appointment A mum who started snoring in her sleep after developing a blocked nose was stunned to discover her single symptom was actually a sign of rare cancer. Claire Barbery, 51, almost cancelled the hospital appointment that led to her diagnosis because she didn't want to "waste the time" of the NHS. ‌ She began experiencing a persistent blockage in one side of her nose but initially put it down to the effects of regular Covid testing while working in a care home. Claire also started snoring in her sleep for the first time and decided to get medical help after using a steroid spray without any improvement in January 2023. ‌ She was referred to an ENT specialist and following scans and a biopsy, doctors broke the devastating news that she had olfactory neuroblastoma – a rare cancer that develops in the upper part of the nasal cavity. The 5cm tumour had already started eroding bone at the base of her skull and she underwent complex surgery to have it removed at Birmingham's Queen Elizabeth Hospital. ‌ Claire, from Newquay, Cornwall, is now urging others to seek medical advice for persistent symptoms, no matter how trivial they may seem. She said: "I very nearly cancelled that appointment because I didn't want to be wasting NHS time. There's nothing wrong, I thought. But looking back, that decision could have cost me my life. "I started snoring, which I'd never done before. I was waking myself up, breathing through my mouth rather than my nose. Even then, I nearly cancelled my hospital appointment. I didn't want to waste anyone's time I just left it and thought it was something to do with having had COVID the month before." ‌ Claire has now teamed up with UK charity Get A-Head Charitable Trust to boost awareness of World Head and Neck Cancer Day. She added: "If you know your body, then you've got to push. If there's something wrong, don't ignore it." The operation in January last year was carried out by consultant surgeon Shahz Ahmed, who specialises in skull base procedures. It was captured as part of the Channel 5 documentary 'Surgeons: A Matter of Life or Death'. ‌ Mr Ahmed said: "Claire had a very rare form of cancer that needed to be removed. Untreated, it could have metastasized and spread into the neck and the rest of the body. It had already gone through the skull base into the base of the brain and if left, it would have become harder and harder to treat." The intricate operation involved extracting the tumour, along with Claire's olfactory bulbs – meaning she has permanently lost her sense of smell – and rebuilding the area between her nose and brain. Mr Ahmed added: "The key worries were operating between the left and the right eye. The main blood supply to the brain is in very close proximity so the risk of seizures, stroke, injury to the brain and loss of life, were all very real. Thankfully, the surgery was a huge success and Claire suffered no complications." After her operation, Claire endured six weeks of chemotherapy and radiotherapy and is now regularly reviewed by her medical team. She's slowly getting back to work and since her treatment ended, she's been enjoying holidays with her husband Gary and spending more time with her daughters Lowenna, 27, and Keizha, 25.

If you're losing weight too fast (more than two to three lbs per week after the initial adjustment period), try: Tracking your food intake to ensure you're eating enough calories (apps like MyFitnessPal can help). Increasing protein intake to preserve muscle mass (aim for 0.6–1g per pound of body weight). Adding healthy fats and complex carbs (e.g., avocados, nuts, whole grains) for balanced energy. Adjust Your Dosage (With Doctor's Approval) If your weight loss is too rapid or causing side effects, your doctor may: Pause dose increases or lower your dosage. Adjust your treatment plan to stabilise your weight loss. Strength Training & Exercise To prevent muscle loss: Incorporate resistance training at least two to three times per week. Stay active with low-impact exercises like walking or yoga. Hydrate & Manage Electrolytes Drink enough water (Mounjaro can reduce thirst). Electrolytes matter - Consider adding magnesium, sodium, and potassium if you feel weak or fatigued. Monitor for Malnutrition & Deficiencies Rapid weight loss can cause vitamin/mineral deficiencies (especially B12, iron, and electrolytes). If you experience: Fatigue, hair loss, or dizziness, ask your doctor about supplements. Consider Further Medical Guidance If your weight loss is excessive or causing health concerns, speak with your healthcare provider. They might adjust your dosage, diet, or exercise plan to help stabilise your weight loss.
