'Golden age' weight-loss pill that mimics gastric bypass op is hailed a 'miracle' - and said to be better than fat jabs
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', addding: 'I think use of drugs like this will prevent the need for many other medications, procedures, and surgeries.

Obese to get soups and shakes diet instead of weight-loss jabs
Low-calorie soups and shakes are to be prescribed to thousands of overweight people in Scotland in an attempt to reduce their dependence on expensive weight-loss drugs and provide longer-lasting health benefits. From January, 3,000 patients who have been newly diagnosed with type 2 diabetes will be recruited for a clinical trial. About 300,000 Scots live with type 2 diabetes, a condition commonly linked to obesity, in which badly regulated blood sugar levels can increase the risk of heart disease, kidney disease, strokes or nerve conditions. About 10,000 of them are being treated with weight-loss drugs such as Ozempic, Wegovy and Mounjaro, with injections costing the NHS £3,000 a year. The estimated annual bill of £30 million is expected to rise as manufacturers raise prices. NHS chiefs believe that not only will the soups and shakes plan be less expensive, it will also bring longer-term health benefits. In the Total Diet Replacement (TDR) plan, to be rolled out over three years, patients who have recently been diagnosed with type 2 diabetes and are deemed eligible will be given low-calorie substitutes for their breakfast, lunch and dinner. The replacement meals, containing a maximum of 900 calories a day, will be delivered to patients for between three and five months. • What to do now Mounjaro's hiking its prices, by an obesity expert After this initial period, normal food will be reintroduced, but with guidance given on healthy meals through online consultations and an app. The ambition is for patients to lose up to 10 per cent of their body weight over a year. Doctors are also optimistic that up to 40 per cent of the trial participants will achieve remission from type 2 diabetes within a year. There are fears that the weight lost through injections — which work by suppressing the appetite — may last only as long as the patient is taking the drug. By contrast, the effects of diet changes should prove more long-lasting and cost effective, NHS officials believe. The TDR scheme is set to cost £5.6 million for 3,000 patients, a one-off cost of about £1,866 per person. Doctors hope the plan will help patients to fundamentally alter their diet and lifestyle. A spokesman for the Scottish government said: 'We anticipate that around 35 to 40 per cent will achieve remission from type 2 diabetes at the end of their first year on the programme, with a majority of patients benefiting from a clinically significant average weight loss of 10 per cent.' This would lead to reductions in blood pressure and contribute to a reduced risk of cardiovascular disease. He added: 'We will measure impact by the number of patients recruited into this programme, the number who achieve remission and the number with clinically significant weight loss.'

This is how we do it: ‘Our lives are absorbed by raising kids, and we struggle to find time for sex'
Sex is still so important to me and I'm happier after – I'm just struggling to get in the mood We have two children under 10, and being a mother to them nearly always takes priority. I rarely have time to do the things that nourish and sustain me – go to the gym, wash my hair, see friends – and by the end of the day I'm too exhausted from mothering to have sex. But when I'm more relaxed and rested, and able to prioritise myself, I'm more in the mood. Scheduling also helps, so if we say, 'Let's have sex on Wednesday,' I go to bed earlier and make time for it. Rich is a great dad and does loads around the house, but I take on more of the mental load and have lost more of myself in parenthood. It's just the way it is. Rich and I met at college. When we reconnected in our 30s, I immediately knew I wanted to have sex with him. We went on a couple of dates and the sex was great; it felt natural, but also exciting and full of desire. We fitted together perfectly. I thought it was just a sexual thing at first, but the morning after the first time, I had this knowing feeling that it was going to last. After a difficult first birth, I couldn't physically have sex for nine months. I had scarring, didn't want anything near there and thought it was the ultimate turnoff. Rich was supportive and patient. We took it slowly, and when we eventually had sex again it felt like a huge relief. Sex is still so important to me, and I'm happier after. I'm just struggling to get in the mood, balancing being a mum with looking after myself and being a sexual being. We now have sex once every month or two, which isn't often enough for Rich. I've never had a high sex drive, and before we had kids we had sex about once a week, usually on a long, lazy Sunday morning. We're going through a tough time, and Rich isn't happy about a few things in our relationship, sex being one of them. I love him, so I'm trying to be more available, but I don't want to have sex out of duty. We're going to start marriage counselling, and I hope that this busy parent stage will pass, and our love, sexual chemistry and commitment will get us through. If you're keen to talk to us about your sex lives you can get in touch by filling in the form below. It is very important that both sexual partners are happy to participate. When Laura does initiate out of the blue, it feels reassuring. I'm careful not to reject her advances Laura and I are very compatible; we have shared values and similar temperaments. My previous relationships were more challenging, so I was surprised how easy it was with her. But once kids came along, that changed. Our lives are now completely absorbed by raising our kids, and we struggle to find time for each other. I was the one who pushed to have children; Laura took some convincing. When trying to conceive took a year, sex became less about pleasure and more of a chore. Then, when you have kids, there's less mystery, and having the same mundane, routine interactions doesn't help to create an erotic environment. Our sex life doesn't fulfil me the way it used to, and I've stopped initiating because it's hard to keep doing that and getting rejected. What we need is to have fun outside the home, get out and be ourselves in the world, and bring more joy and colour back into our lives. When Laura does initiate sex out of the blue, it feels reassuring. I'm careful not to reject her advances, even when I'm feeling a bit unwell, because I don't want months without sex to lead into more. We try to make time four to six times a year to enjoy and pleasure each other. It can be hard to get into the headspace, but we build up anticipation by talking about it, so half the work is already done before we've even taken off our clothes. As I get older, I am reminded that life is finite. I'd love to have the joy and possibility of being more sexual, to feel confident to initiate again, and even get that dynamic back from 10 years ago, when we had sex once a week. Just non-spectacular, comfort sex that says: 'I see you, I want to be with you, I love you.' Sex makes everything feel more positive, and life is a little easier.

Dylan Sprouse's wife Barbara Palvin, 30, gets secret surgery after suffering 'sleepless nights on the floor'
Barbara Palvin opened up about a private health struggle and why she stepped away from the spotlight for several months. In a candid post, the 30-year-old supermodel revealed that she recently underwent surgery after years of painful and debilitating periods led doctors to suspect endometriosis. 'Hi guys, it's been a while!' she began, before explaining that she had long believed her severe symptoms were simply part of her cycle. She continued: 'For some years now I've been dealing with the difficulties that can come with my periods. Fatigue, severe pain, heavy and irregular flow, sleepless nights on the bathroom floor. I thought this was just how it works for me.' It wasn't until she was advised to see an endometriosis specialist that she began to understand the root cause. 'I've been going to checkups to my gynecologist every year, I thought if I had endometriosis I would have known about it by now, but as it turns out, endometriosis can't be diagnosed with general examinations,' Palvin explained. 'So I went, and 3 months later I got operated on.' Barbara Palvin opened up about a private health struggle and why she stepped away from the spotlight for several months Since the surgery, Palvin says she finally knows what it feels like to have a manageable cycle. 'Since then I finally experienced a period that was easier, and now I know the difference,' she said, adding that she wants to encourage others who may be struggling with similar symptoms to seek medical guidance. She added: 'If you suspect that you could have endometriosis I encourage you to find it out. It helped me a lot, and I'm grateful I did it. Early diagnosis and treatment are very important to prevent long-term complications, and now I'm more mindful about my body to act fast if needed.' The Hungarian model — who married actor Dylan Sprouse in 2023 — also shared that she took time to rest and recover after the procedure. 'That's also why I took the past 3 months to rest and fully heal. I'm excited about this new chapter of my life and now ready to get back to work,' she concluded. Palvin, who has walked runways for Victoria's Secret and Armani, joins a growing number of celebrities speaking out about endometriosis, a condition estimated to affect 1 in 10 women of reproductive age worldwide. By sharing her story, she hopes to raise awareness and encourage others not to ignore symptoms that may signal something more serious.
