Experts warn weight loss drug semaglutide isn’t a miracle fix 

A weight-loss jab loved by celebs and now available on the NHS is not a miracle fix for obesity, leading experts warned today.

Tens of thousands of overweight Brits will be given Wegovy after health watchdogs gave the weekly injection the green light, in a move described as a pivotal moment in the country’s battle against the bulge.

Yet questions are already being asked about whether semaglutide is really a ‘game-changer’.

Trials have shown that users can rapidly pile pounds back on once they stop taking the fat-fighting drug, dubbed ‘Hollywood’s worst-kept secret’ and used by the likes of Elon Musk.

Professor Jane Ogden, a health psychologist at the University of Surrey, said: ‘It’s no magic pill.’ 

Dr Adam Collins, an associate professor of nutrition, also at the University of Surrey, added: ‘The most concerning aspect of these therapies is their longevity. The drug is very effective when you are taking it, and so far, has been shown to take for several months. 

‘Yet the guidelines currently are that this is only advocated for use over two years.

Alex Guevara, 46, (pictured) is a paramedic practitioner from Milton Keynes. He has three children, and lives with his wife Christina, 29. He said: ‘When a friend told me about semaglutide I felt I had nothing to lose. I went to a private clinic, and paid £250 a month for six months’

Semaglutide, marketed as Wegovy, will be available in pharmacies from the spring

‘So, what happens when you come off of the drug? The answer is, your hunger will return in spades.’

Dr Collins added: ‘With the shackles off your appetite, plus other changes… you are super primed to regain that lost weight. 

‘We also know in this scenario people are highly susceptible to overshooting their original weight. 

‘In this context, semaglutide is just another, albeit very effective, means of getting people to lose weight. 

‘But the trick is not losing weight, that is easy, It is maintaining that weight that is the true challenge. It remains to be seen how the emergence of this new class of drugs can be used to meet this challenge.’

Professor Jason Halford, from the School of Psychology at the University of Leeds, told BBC Radio 4: ‘I think it’s one of the most powerful pharmaceutical tools to date that we’ve had access to.’

However, he said that the drug needs to be taken in the context of specialist weight management services, which he claimed there are not enough of in the UK, making the treatment hard for many to access.

He added: ‘What we know when you come off the drug at two years, you see rapid weight gain because you’ve no longer got that drug-suppressing appetite systems.’

But Professor Halford added that once data of the drug’s longer-term effects is available, providing it is deemed safe, it may be used for a much longer period by people who struggle to keep weight off.

Semaglutide – sold under the brand name Wegovy – works by hijacking the brain to suppress appetite and reduce calorie intake, resulting in substantial weight loss. 

It does this by mimicking the hormone glucagon-like peptide-1 (GLP-1), which is released after eating. 

Trials found those on it lost around 12 per cent of their body weight – and slashed their chances of type 2 diabetes by more than half.

Alongside the drug, participants ate 500 calories fewer than they burned each day — so they had a calorie deficit — and were told to exercise for two-and-a-half hours per week.

But one study found that patients then put back on two-thirds of the weight in the next year, once the trial stopped.

The drug is already given at much lower doses to treat patients with type 2 diabetes, under the brand name Ozempic. Private clinics in the UK have given clients Ozempic off-label for just under £200 per month.

TikTok star Remi Bader, who has 2.2million followers on the social media site, was prescribed Ozempic by her doctor in 2020. This drug also contains semaglutide, at a lower dose, and is used to treat patients with type 2 diabetes.

She said she put on ‘double the weight’ she lost when she came off the drug because her binge eating got ‘so much worse’.

Ciara Lawless, 40, from Dublin, lost 2st (28lbs/12.7kg) in May 2020 after getting semaglutide injections when she weighed around 12 and a half stone. She said she maintained her weight after coming off the jab through healthy eating and a weekly treat but has since used the jab ‘for help’ when she ‘needs it’

Danielle Breckenridge, 31, (pictured before the weight loss, left, and after, right) says she also lost more than 2st after taking semaglutide injections

Some patients have told of how they have had to stop taking the drug due to side effects. 

Users commonly complaining of nausea, constipation and diarrhoea after taking the medication.

It has also been known to make food less appealing, potentially ruining the enjoyment of eating altogether.

US comedian and TV host Chelsea Handler revealed she took the drug after being prescribed it by her doctor — but said it made her nauseous. 

Some also suffer from acid reflux, fatigue and complain that food tastes different after taking the drug.

It is this side effect that some people credit for further assisting their weight loss — by making their favourite junk food taste bad. 

Thyroid cancer, pancreatitis — when the organ becomes inflamed — and kidney failure are rare but serious side effects.

Patients have also warned of their face appearing gaunt, exhausted and old — a side effect that has been labelled ‘Ozempic face’.

And all the trials so far have seen it dished out alongside strict exercise and calorie-restrictive diets – two proven ways of losing weight. 

Doctors have warned that while the drug is an example of ‘very smart science’, it is ‘not a panacea for everyone’, as it doesn’t work for one in five patients. 

However, experts welcomed NICE’s recommendation for Wegovy for those with a Body Mass Index (BMI) of 30 and above, as part of a weight-loss programme of diet and exercise.

Tam Fry, from the National Obesity Forum, said this is ‘the weight-loss drug that we’ve been waiting for’ and urged health leaders to ration supplies to those in greatest need.

He said: ‘It’s a game-changer and so successful that Hollywood A-listers are now using it to slim and show off their figures.

‘The real danger is that there may not be enough to go round in the short-term.

‘You should not be using it just to lose a few pounds because that might will jeopardise the health of those who really need it, those who have diabetes type 2 and morbid obesity.’

Ashton Olivia Smith, 33, from Tulsa, Oklahoma , shared before and after photos of her 40lb weight loss on TikTok after taking the weight loss drug for nearly a year and a half. The mother-of-four said: ‘If you’re looking for a sign to start Wegovy/Ozempic, HERE IT IS!’

Khalin Grant, 41, from Florida, says she lost 75lbs in seven months while taking weekly injections of Wegovy. Ms Grant says she now fits into smaller dress sizes than when she was in college

The drug has been hailed a miracle cure by some who have taken it. 

Alex Guevara, 46, is a paramedic practitioner from Milton Keynes. He has two children from his first marriage, and a third with wife Christina, 29, who’s also a paramedic.

He said by April last year he was touching 20st and his weight left him feeling suicidal. 

Mr Guevara started on semaglutide and within a few days said he started feeling less hungry and felt much happier. He quickly lost four stone.

‘I needed something dramatic to break the cycle and stop me hurtling towards type 2 diabetes, cardiovascular diseases and stroke,’ he added. ‘Semaglutide should be available to anyone who needs it.’ 

Made by Novo Nordisk, it is hoped the jabs – which will initially help around 35,000 people a year – will be available to patients within weeks as part of NHS specialist weight management services.

Adults with a BMI classed as obese and at least one weight-related illness such as pre-diabetes, type 2 diabetes, high blood pressure, cardiovascular disease or high blood pressure, could qualify.

The jabs are self-administered by patients once a week using pre-filled pens, for a minimum of 16 weeks.

They can initially be placed on the drug for a maximum of two years, although regulators say there is scope to increase this if real-world data shows it continues to be an effective weight loss tool.

Around 19million people in England are obese, which costs the NHS more than £6billion a year.

Trials found patients given the weekly jab lost a tenth of their body weight in just 20 weeks – 25 times more than those on a placebo – consuming around 35 per cent fewer calories.

Wegovy works by triggering the body to produce a hormone called glucagon-like peptide-1 that is released naturally from the intestines after meals

A UK study found that people who used Wegovy experienced rapid weight loss, dropping 18% of their weight over 68 weeks. They regained two-thirds of that weight, or 12% of their original body weight in the year after dropping the weekly injections. Experts says the drug needs to be used over a lifetime to keep off the pounds

Kim Kardashian is rumoured to have used Wegovy to rapidly lose weight in order to fit in Marilyn Monroe’s famous ‘Happy Birthday Mr President’ dress at the 2022 Met Gala (pictured) 

Overweight and obese participants given regular doses also saw their odds of suffering type 2 diabetes fall by up to 61 per cent.

Professor Alex Miras, an endocrinologist and obesity expert at Ulster University in Northern Ireland, said the drug will make a massive difference to people living with obesity.

‘This decision made by NICE is a pivotal moment for the treatment of people living with obesity,’ he said, adding: ‘The weight loss that can be achieved with this safe medication is substantial and likely to lead to the improvement of obesity related complications in a large number of patients.’

It has led celebrities Elon Musk and Jeremy Clarkson to both publicly credit it with helping them to shift the pounds.

Meanwhile, Kim Kardashian was rumoured to have used it to rapidly lose 16lbs (7.3kg) to fit into Marilyn Monroe’s iconic ‘Happy Birthday Mr President’ dress at the 2022 Met Gala.

Helen Knight, director of medicines evaluation at NICE, said: ‘For some people losing weight is a real challenge which is why a medicine like semaglutide is a welcome option.’

Dietitian Dr Duane Mellor, of Aston Medical School at Aston University in Birmingham, said: ‘It is important to remember that semaglutide works alongside and supports healthy lifestyle changes.

‘When people are being offered semaglutide they are also given ongoing support to make changes and maintain these changes with respect to diet and lifestyle.

‘As all individuals initially being offered semaglutide via the NHS will be supported by specialist weight management services this should including support from a specialist dietitian.’
