10 questions everyone’s asking about weight loss jabs right now
Anna-Louise Dearden | Last update: 6th August 2025
From Mounjaro to Wegovy, weight-loss jabs are the hottest topic in health right now. But with all the hype comes confusion. Whether you’re just starting out, or already a dozen doses in – here are the big questions real SlimrChat users are asking – answered clearly, simply and with no fluff (and if you have a little spare time, all the questions have links to more detailed answers)
1. How do these weight loss jabs actually work?
Weight loss medications like Wegovy (semaglutide) and Mounjaro (tirzepatide) mimic hormones called GLP-1 and GIP. These hormones regulate appetite, blood sugar, and digestion – basically they help you feel fuller, eat less, and lose weight without white-knuckling it. Read our explainer: How GLP-1 jabs work
2. What’s the difference between Wegovy and Mounjaro?
Wegovy is GLP-1 only; Mounjaro combines GLP-1 with another hormone (GIP) and tends to work faster for some. People report bigger losses with Mounjaro – but it also comes with stronger side effects.

3. Is it true you can get gallstones or pancreatitis from the jabs?
Recent headlines have flagged a small number of cases where people taking GLP-1 weight loss drugs experienced acute pancreatitis. The UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) is now looking into these reports. But topline – these are rare side effects and often linked more to rapid weight loss or pre-existing conditions than the drugs themselves.

4. Will I regain all the weight if I stop taking it?
Not necessarily. But without changing habits around food and movement, it’s a risk. You have to work with the meds, and not let them do all of the hard work. And then moving forward, maintenance and good habits will be easier. Read: For long term weight loss Mounjaro won’t do it all
5. What should I eat when I’m not hungry?
If you’re taking GLP-1 meds like Wegovy or Mounjaro, chances are your appetite’s already taken a hike, so protein is queen. Your body still needs nutrients to preserve muscle and energy. Think smoothies, yoghurt bowls, eggs, and soft proteins. Try our roundup: 7 summer-friendly high-protein meals for jab users
6. Can the jabs actually help fight cancer?
A new study in Science Daily says Mounjaro may slow the growth of obesity-linked breast tumours. It seems that for people living with obesity, the benefits of GLP-1 medications like Mounjaro go far beyond just weight loss. It’s early days – but promising.

7. Do I have to give up everything I like?
Losing weight with GLP-1 medications is a powerful step toward a healthier you, but it should never mean giving up the things you enjoy in life. Life doesn’tt stop when you start GLP-1 treatment – you can still enjoy good food, travel, social events, and hobbies. Focus on creating a lifestyle that feels good and keeps you motivated over the long term. Read: Set lifestyle goals, not just weight goals.
8. Can I drink alcohol while on these meds?
Technically, yes – but many users find their tolerance changes. Plus, alcohol can irritate your gut and reduce progress, but it’s not a no-no. Check out our chat threads on this and read: Managing booze on weight loss drug.
9. Where can I get weight loss drugs safely in the UK?
It’s crucial to go through regulated providers. Counterfeit jabs are in the market, and the FDA (in the USA) recently cracked down on fake versions of Mounjaro and Ozempic. These unlicensed products often look convincing, complete with packaging that mimics real brands, but they can contain dangerous substances, the wrong dose, or no active ingredient at all. The authorities in the UK are hyper vigilant too. Read: The danger of fake weight loss jabs – what you need to know
10. Is this just another diet trend – or a proper medical treatment?
GLP-1s aren’t a fad – they were developed for diabetes and are now being used to treat obesity, a recognised chronic disease. The science is solid, and the NHS is even rolling it out in pilot schemes. But it’s not a magic fix – think of it as a tool, not a cure.
