While a medicine that reverses the clock would be a miracle, we're not quite there, yet.
But scientists hope the 'game-changing miracle' weight loss injections like Ozempic, Wegovy and Mounjaro, could be the next best thing, helping us live longer.
Just last week, a study found that semaglutide - the active ingredient in Ozempic and Wegovy - could "significantly" slash the risk of the brain-robbing disease dementia, in people with type 2 diabetes.
Researchers at Case Western Reserve School of Medicine in Cleveland, Ohio, studied 1.7million American patients with type 2 diabetes over three years.
Originally designed to treat type 2 diabetes, the jabs mimic a gut hormone called GLP-1.
This leads to a reduction in appetite and regulates blood sugar levels.
Now, they are prescribed to help melt fat away, and are taking the nation's waistline by storm.
And new research is showing that these jabs could reduce the risk of various deadly diseases, from heart disease to Alzheimer's and cancer.
They could also prevent deaths from these conditions, according to results of the SELECT trial, published in 2023.
Funded by Ozempic and Wegovy manufacturer Novo Nordisk, it tracked 17,600 people either given the jab, or a placebo, for three years.
Weight Loss Jabs - Pros vs Cons
All of the volunteers taking part were overweight, over the age of 45 and had been diagnosed with cardiovascular disease.
During the trial, 833 people died. But those who were on fat jabs were 19 per cent less likely to die of any cause, and 15 per cent less likely to die a heart-related death.
Levels of inflammation in the body were also reduced, regardless of how much weight was lost.
This is one of the key theories behind why fat jabs may have additional benefits.
Inflammation, triggered by obesity and associated lifestyle choices, is often what drives heart disease and other major causes of death.
'We know that chronic inflammation speeds up ageing,' Dr Amos Ogunkoya, a GP in London, tells Sun Health.
'It causes DNA damage - and that's the reason diabetes and obesity increase the risk of certain cancers and tissue damage.
'The more inflammation you have, the more DNA damage you have.'
Professor Rameen Shakur, a molecular biologist and director of Brighton Integrative Genomics Unit, says: 'We do know that turning down chronic systemic inflammation helps in healthy longevity.'
But he adds: 'Ageing is a complicated soup of systems and signals which is, over time, weakening and decaying the cells that keep our body fit and well.
'It's a multi-dimensional complex, not one thing.
'Ageing involves free radicals, telomeres and general decay. If I have Botox, I won't have wrinkles, but it won't positively affect my heart.
'There's no study that says, 'I took Ozempic and now I'm Benjamin Button'.
We know that chronic inflammation speeds up ageing

'We don't understand if it 'reverses the clock'. But it has additional effects because it reduces calories [eaten].'
What is certain though is that like all medicines, weight loss jabs do come with a range of side effects, most commonly nausea, diarrhoea and constipation.
But there are also more serious risks, including pancreatitis and gastroparesis.
So while there are risks, for those Brits who are overweight and either already living with, or en route to a chronic illness that could shorten their life, doctors agree these jabs have huge potential to improve lives.
So what does the science say? Here's how Ozempic could extend your life…
HEART OF IT

LOSING weight has huge benefits on the heart.
'Living with excess weight or obesity can increase the chances of developing cardiovascular disease,' Dr Sonya Babu-Narayan, clinical director at the British Heart Foundation and consultant cardiologist, tells Sun Health.
'The SELECT trial, which involved people with pre-existing cardiovascular disease, found that semaglutide can reduce the risk of dying from cardiovascular disease, or having a heart attack or stroke by around 20 per cent.
'Plus, it was found that semaglutide can reduce the risk of heart attacks and strokes in people with pre-existing cardiovascular disease, even if they didn't lose weight.
'This suggests that the medicines are having other positive effects, such as where fat is stored, and regulation of blood sugar, blood pressure and inflammation.'
Diabetes, high blood pressure and high cholesterol are all associated with obesity, and have a negative impact on the heart and blood vessels.
THE BIG C
OBESITY is the second most common cause of cancer in the UK, behind smoking.
But scientists believe the jabs' influence on inflammation, hormones and chemicals in the blood might add extra protection against cancer.
One study compared 3,200 patients who lost weight with GLP-1 injections with 3,200 who had surgery.
The jabs were 41 per cent more effective at preventing cancer, the researchers from Israel reported in eClinicalMedicine.
Dr Matthew Harris, of the Manchester Cancer Research Centre, added: 'Injectable weight loss medications give a genuinely promising possible option for cancer prevention in the future.'
Another study found diabetics on GLP-1 drugs were less likely to get 13 types of cancer associated with obesity over 15 years, from pancreatic to bowel and womb, than those on other meds.
Everything you need to know about fat jabs
Weight loss jabs are all the rage as studies and patient stories reveal they help people shed flab at almost unbelievable rates, as well as appearing to reduce the risk of serious diseases.
Wegovy – a modified version of type 2 diabetes drug Ozempic – and Mounjaro are the leading weight loss injections used in the UK.
Wegovy, real name semaglutide, has been used on the NHS for years while Mounjaro (tirzepatide) is a newer and more powerful addition to the market.
Mounjaro accounts for most private prescriptions for weight loss and is set to join Wegovy as an NHS staple this year.
How do they work?
The jabs work by suppressing your appetite, making you eat less so your body burns fat for energy instead and you lose weight.
They do this my mimicking a hormone called GLP-1, which signals to the brain when the stomach is full, so the drugs are officially called GLP-1 receptor agonists.
They slow down digestion and increase insulin production, lowering blood sugar, which is why they were first developed to treat type 2 diabetes in which patients' sugar levels are too high.
Can I get them?
NHS prescriptions of weight loss drugs, mainly Wegovy and an older version called Saxenda (chemical name liraglutide), are controlled through specialist weight loss clinics.
Typically a patient will have to have a body mass index (BMI) of 30 or higher, classifying them as medically obese, and also have a weight-related health condition such as high blood pressure.
GPs generally do not prescribe the drugs for weight loss.
Private prescribers offer the jabs, most commonly Mounjaro, to anyone who is obese (BMI of 30+) or overweight (BMI 25-30) with a weight-related health risk.
Private pharmacies have been rapped for handing them out too easily and video calls or face-to-face appointments are now mandatory to check a patient is being truthful about their size and health.
Are there any risks?
Yes – side effects are common but most are relatively mild.
Around half of people taking the drug experience gut issues, including sickness, bloating, acid reflux, constipation and diarrhoea.
Dr Sarah Jarvis, GP and clinical consultant at patient.info, said: 'One of the more uncommon side effects is severe acute pancreatitis, which is extremely painful and happens to one in 500 people.'
Other uncommon side effects include altered taste, kidney problems, allergic reactions, gallbladder problems and hypoglycemia.
Evidence has so far been inconclusive about whether the injections are damaging to patients' mental health.
Figures obtained by The Sun show that, up to January 2025, 85 patient deaths in the UK were suspected to be linked to the medicines.
MIND MATTERS
STUDIES suggest semaglutide may reduce the risk of Alzheimer's - the most common form of dementia and the leading cause of death in the UK.
One, published in the journal Alzheimer's and Dementia, found that type 2 diabetics had a 40 to 70 per cent reduced risk of Alzheimer's when they were on semaglutide compared to other diabetic drugs.
Another, published in JAMA Neurology, showed a 33 per cent lower risk.
The researchers said it's not clear how the drugs are protecting the brain, but inflammation is thought to play a major role in the development of Alzheimer's.
Dr Amos says: 'Inflammation causes damage to neurons (in the brain).
'It's also quite common for people's Alzheimer's or their cognitive decline to get worse when they're ill because inflammation markers are high.'
A study by Imperial College London also showed that liraglutide (Saxenda) could reduce brain shrinkage in patients already with Alzheimer's, by 50 per cent.
BUT WHAT ABOUT 'OZEMPIC FACE'?

WHILE Ozempic-like jabs might have internal anti-ageing benefits, there's a danger they could make you look older.
''Ozempic face' is a loss of volume in the face, which can visually make wrinkles look worse,' warns Dr Amos.
'When you lose fat in your face, and your skin doesn't follow, you can look saggy and older.'
Rapid weight loss also means a loss in muscle mass, which helps define a figure and reduce loose skin.
It's also important the more you age to reduce frailty, and protect bones.
Dr Amos recommends weight training while on weight loss jabs.
He says: 'Lots of people are getting Ozempic privately and they're not aware of the side effects of muscle loss and not training or changing their lifestyle.'

Weight-loss injections could make you fitter without exercise
Weight-loss jabs could help people become fitter by making their muscles work more efficiently, evidence suggests. Anecdotally, there is concern among people who use treatments such as Mounjaro that weight loss will make them less muscular, toned and strong. However, a study analysing the body composition of more than 200 people with type 2 diabetes, found they lost no more muscle after a weight-loss jab than if they had lost weight by other means. Meanwhile, they shed significantly more fat from within their muscles than they would have done losing weight another way. • The weight-loss drugs guide: how to avoid the side effects The loss of fat from the muscles after taking tirzepatide, the prescription injection sold as Mounjaro, could also boost someone's capacity to do physical activity. That is because 'ectopic' fat found within the body, which gets into muscles and wraps in and around other organs, has been linked with poorer muscle strength and physical performance in both men and women. Naveed Sattar, the lead author of the study and a professor of metabolic medicine at the Institute of Cardiovascular and Medical Sciences at the University of Glasgow, said: 'For the majority of people using the weight-loss injection tirzepatide, they experience an increase in their capacity for activity, meaning they can often walk for longer or be more active than before. 'Having less muscle fat usually means the remaining fat muscle cells are more efficient in generating power, which could explain the boost to people's exercise abilities. These results are hugely encouraging as less muscle fat is also linked to a reduced risk of cardiovascular disease and type 2 diabetes in many studies. 'However, we don't yet know how weight-loss injections remove additional muscle fat, and more evidence is needed to understand the mechanisms involved.' Fat streaks within the muscles tend to increase when someone is more overweight or sedentary. They can be reduced through aerobic exercise such as jogging, walking and cycling. But the use of weight-loss injections to achieve a similar result could be useful for people who are unable to be as active because of their excess weight. • 'After taking weight-loss drugs, my life fell apart' The research, published in the journal The Lancet Diabetes & Endocrinology, looked at 246 people given varying doses of tirzepatide, or insulin in a previous study. An MRI scan was used to quantify the amount of muscle and fat each person had in their thighs before the treatment, and a year after starting it. The amount of muscle lost by people using tirzepatide was compared to typical muscle loss in people of the same age and sex, losing the same amount of weight. Muscle loss was broadly similar for both groups. However, the percentage of fat lost from their muscles was 0.5 per cent higher if they took tirzepatide than would be expected from losing the same amount of weight without the drug. Researchers worked this out using data for almost 3,000 people taken from the long-running UK Biobank health study. It may be that tirzepatide not only makes people feel fuller for longer and less hungry, but also removes ectopic fat from different parts of the body better than conventional weight loss. That could help to explain evidence suggesting weight-loss injections may reduce the risk of diabetes and many other chronic diseases.

Urgent weight loss jab warning as 'common mistake' can lead to organ failure
Around 1.5 million people in the UK are thought to be using weight loss jabs, with many paying privately as NHS supplies remain limited - but some dangerous side effects have been reported A nurse has issued a stark warning to Brits using Mounjaro, claiming a "common mistake" could put them at risk of life-threatening organ failure. Dubbed the "King Kong" of slimming injections, Mounjaro is now available on the NHS to help tackle the UK's obesity crisis. But experts warn thousands of patients may be vulnerable to serious side effects because GPs are failing to carry out one crucial blood test. Rachael Joy, a nurse and chief clinical officer at private healthcare provider SheMed, told Mail Online: "The safest way for people to use these jabs is through mandatory blood screening." She explained that simple blood tests could flag up hidden health issues that might make the jabs unsuitable, such as liver problems, uncontrolled diabetes or dangerously high levels of triglycerides - a type of fat in the blood that can raise the risk of pancreatitis. 'If someone has really high triglycerides, they may be at higher risk of pancreatitis,' she warned. Pancreatitis - an inflammation of the pancreas, the organ behind your stomach - can trigger organ failure and even prove fatal in severe cases. Experts believe high fat levels, combined with dehydration and other factors, could make certain people more vulnerable. Ms Joy added: "People with uncontrolled diabetes are also at greater risk of becoming severely dehydrated, which can be very serious. Without a blood test, this could be missed." The warning comes as the UK's medicines regulator investigates whether some people have a genetic trait that increases their risk of dangerous side effects from "GLP-1" drugs like Ozempic, Mounjaro and Wegovy. The Medicines and Healthcare products Regulatory Agency (MHRA) confirmed it is probing more than 560 reports of pancreatitis linked to the jabs since their launch, including 10 deaths. Dr Alison Cave, the MHRA's chief safety officer, said: 'Evidence shows almost a third of side effects to medicines could be prevented with genetic testing.' Adverse drug reactions already cost the NHS an estimated £2.2 billion a year in hospital stays alone, and account for one in six hospital admissions. While Mounjaro has been hailed as a game-changer for weight loss and for lowering blood sugar in people with type 2 diabetes, Ms Joy cautioned it is 'not a silver bullet' and can cause serious side effects, including nausea, diarrhoea and dehydration. Severe dehydration can lead to headaches, dizziness and, in rare cases, seizures or kidney failure if untreated. She is now urging healthcare bosses to impose stricter safety guidelines for prescribing the jabs, warning that busy GPs are under huge time pressures. At SheMed, blood tests are mandatory before patients are approved for treatment, but Ms Joy fears this isn't always happening elsewhere. The MHRA is also urging anyone who suffers side effects to report them through its Yellow Card scheme. Genetic screening is being explored as a way to make prescribing safer in future. Professor Matt Brown, chief scientific officer of Genomics England, said: 'Medicines like GLP-1s can be transformative, but like all treatments, there's a risk of serious side effects. Many adverse reactions may have a genetic cause, and genetic screening could be the key to safer, more personalised treatment.' Around 1.5 million people in the UK are thought to be using weight loss jabs, with many paying privately as NHS supplies remain limited. The main warning sign of pancreatitis is severe stomach pain radiating to the back that doesn't go away. Anyone experiencing this is urged to seek urgent medical attention.
