IT'S impossible to escape the hype around weight loss jabs.
Whether it's wild before-and-after pictures flooding social media or the feral gossip each time a celebrity posts a snap of themselves appearing to look far slimmer than before.
The surprising ways science says fat jabs could boost your healthNow, we're being faced with a barrage of studies claiming the jabs might be good for more than just shedding the pounds.
Most recently, scientists said the medicines could be the cancer hope of the future, and after early studies suggested they could reduce the risk of tumours, for example.
The jabs work by mimicking a hormone called GLP-1, which is normally released after eating.

Over the last few years, several medicines containing synthetic hormones have become available in the UK.
Ozempic - whose active ingredient is semaglutide - is prescribed to treat type 2 diabetes and has the added benefit of making users lose weight.
Its manufacturer, Novo Nordisk, released a higher dose of semaglutide under the brand name Wegovy to treat obesity, which was rolled out in the UK last year.
The Mounjaro KwikPen, which contains tirzepatide but works in a similar way, has been approved by UK regulators as a diabetes and weight loss treatment.
Another option is liraglutide, which is prescribed on the NHS as Saxenda to tackle obesity.
But away from weight loss, here are all the other benefits scientists are claiming the jabs might have.
It could slash the risk of cancer...
Fat jabs could be the cancer hope of the future after early studies found they reduce the risk of tumours growing.
The world’s top experts are preparing for a research boom to find out if the wonder drugs can head off the most feared disease.
Research by Case Western Reserve University in Ohio found obese people were 19 per cent less likely to get cancer if they used the injections than people who did not.

Other findings also suggest the injections’ rapid weight loss could help breast cancer survivors avoid relapse, which is more likely in fat patients.
Experts suggest about four in 10 cancers are linked to obesity, particularly bowel and breast tumours which are some of the most common.
It might cure snoring...
Researchers say the fat-blasting jabs can silence snoring by treating an underlying health condition called sleep apnoea.
It happens when your breathing stops and starts while you are asleep, causing people to gasp, snore and wake up spluttering during the night.
Around 10million Brits are thought to have it, according to the Sleep Apnoea Trust.
Being overweight or obese can increase a person's risk of the condition by narrowing the airways.
After conducting two studies on adults with obesity and sleep apnoea, drug maker Eli Lilly claimed its fat jab Mounjaro could cut down the number of times people had breathing issues during the night.
After 52 weeks, those given 10 to 15 mg injections of Mounjaro, on average, experienced almost 30 fewer dangerous breathing events per hour, amounting to a 55 per cent drop.
By contrast, participants taking a placebo medication only had 4.8 fewer events, a five per cent reduction.
At the same time, those taking the weight loss drug also shed about 18 per cent of their body weight, which the pharma giant has said could be directly behind the reduction in nighttime disturbances.
It may ward off Alzheimer's...
Medications like Ozempic and Wegovy could affect cognitive disorders and even ward off Alzheimer's.
The thought stems from a Danish study that followed people with type 2 diabetes for five years.
The scientists found those on weight loss jabs were less likely to develop dementia compared to those not on the drug.
However, obesity - which is associated with type 2 diabetes - is already known to increase the risk of Alzheimer's, according to the Alzheimer's Society.
This suggests it could just be the slimming effects that give it benefits against the disease.
More than 600,000 people in the UK have Alzheimer’s disease, the number one cause of dementia.
It is a brain disorder that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks.
Two trials which started in 2021 are assessing the effects of semaglutide versus placebo in people with early stages of the disease.
However, since the disease takes a long time to take hold, the results are not expected until after 2026.
In the meantime, there are lifestyle changes you can make to reduce your risk of developing the condition.
These include keeping active, eating a healthy diet, maintaining a healthy weight, and quitting smoking.
It could boost your fertility...
Some women have reportedly become pregnant unexpectedly after taking semaglutide jabs.
This has led to some doctors in the US prescribing the medicine to treat polycystic ovary syndrome (PCOS), one of the leading causes of infertility in women.
Many people with the condition are overweight and found to have higher levels of testosterone, which is usually thought of as a 'male hormone'.
Researchers reckon weight loss drugs could help regulate hormones in people with PCOS and so reduce symptoms and complications.
A study involving 27 obese patients diagnosed with PCOS found that after six months of taking semaglutide, they lost an average of 25lbs (11.5kg) and had more regular periods, suggesting their PCOS was improving.
Another, carried out by the Women's Hospital in Los Angeles, found that liraglutide - the active ingredient in Victoza and Saxenda - significantly reduced testosterone levels.
However, British scientists have recently warned these jabs could cause birth defects and should not be taken within two months of trying to conceive.
Weight loss, on the whole, can increase fertility because being overweight can interfere with hormone levels.
But semaglutide has never been tested on pregnant women, so we don't know how it would affect them or their babies.
Weight loss injections could do far more than that, scientists hopeCredit: GettyIt might slow down ageing...
As people get older, they tend to shed muscle and gain body fat, which feeds into conditions often seen in older adults, such as frailty and loss of muscle mass and strength.
There are some trials happening now which are looking into whether drugs such as semaglutide can slow this process down.
Dr Tiffany Cortes, of the University of Texas, is running one such trial.
She said the hope was that the ingredients used in fat jabs could help older people regain physical function, whether through direct weight loss or other means.
While fat jabs might keep your body looking young, they might have the opposite effect on the face.
Users have been sharing their experiences of side effects dubbed 'Ozempic face' - a term used to describe the gaunt look caused by the skin losing collagen after major weight loss.
It might help people give up drugs, cigarettes or booze...
As it turns out, weight loss jabs can crush drug cravings in the same way they stop the urge to eat.
The jabs are known to promote feelings of fullness and, it seems, dampen the reward associated not only with food but also drugs.
A Penn University study found liraglutide was as good as a fortnight in rehab for people addicted to painkillers.
Tests on 20 people recovering from opioid addictions revealed patients who took the jabs once a day rated cravings 40 per cent lower than those having rehab.
While some patients experienced no cravings at all.
And earlier studies on rodents suggested the treatment could also work for nicotine and cocaine addiction.
Other scientists are looking into its effects on alcohol addiction.
The idea came about after people given GLP-1 drugs for diabetes reported reductions in their booze consumption.
It can reduce your chance of heart attack or stroke...
The skinny jab could also cut your risk of a heart attack, according to researchers.
Being a healthy weight can slash your risk of developing heart and circulatory diseases like strokes and vascular dementia.
That's because carrying excess weight can lead to fatty substances building up in your arteries, the British Heart Foundation (BHF) warns.
If an artery that's job is to carry blood to the heart gets clogged, it can trigger a heart attack.
And if the same thing happens in an artery carrying blood to the brain, this can cause a stroke.
So, perhaps it is hardly surprising that injections that can help you lose weight might also reduce your risk of cardiovascular problems.
One study found getting 2.4mg injections of semaglutide like Wegovy a week could reduce the risk of 'major adverse cardiovascular events' by 20 per cent.
That's according to a piece of research conducted by the drugs maker Novo Nordisk, which makes Wegovy.
The 2023 study involved 17,604 adults over 45 who were overweight or obese with cardiovascular disease and no history of diabetes.
The participants were split into two groups. One group was given the Wegovy injection, while the other received the placebo.
It might be able to slow down Parkinson's...
For decades there have been few advancements in the battle against Parkinson's.
But French researchers reported the first glimmer of hope - a modest slowing of the disease in a one-year study among people who used the weight-loss jabs.
Parkinson's is a devastating nervous system disorder affecting 10 million people worldwide, with no current cure.
Symptoms include tremors, slowness and stiffness, and difficulty with balance.
That can lead to difficulty walking, talking and swallowing. Many patients develop dementia.
The paper, published in The New England Journal of Medicine, involved 156 people with early Parkinson’s disease who were randomly assigned to take the drug — lixisenatide -or a placebo and followed for a year.
During that time, Parkinson’s symptoms like tremor, stiffness, slowness and balance worsened in those taking the placebo but not in those taking the drug.
The effect was "modest" according to the researchers.
However, this may just be because Parkinson's disease worsens slowly, and with another year of follow-up, the differences might become much bigger, they added.
Studies have repeatedly found that people with type 2 diabetes are at increased risk for Parkinson’s disease.
However, that increased risk declines in those who take a GLP-1 drug to treat their diabetes.
According to Parkinson's UK, diabetes drugs like lixisenatide are being scrutinised by scientists for treating Parkinson's because GLP-1 receptors are also found in the brain.
Previous experiments have found that activating them could boost dopamine, have anti-inflammatory properties, improve energy production, and switch on cell survival signals.
Lixisenatide is the second diabetes drug to go through clinical trials for Parkinson’s, the first being exenatide.
