Fat Jabs. A Gym Owner’s Nightmare or Best Friend?
Over the last 12 months, weight loss injections like Ozempic, Wegovy, and Mounjaro have gone from obscure medical treatments to mainstream weight-loss hacks, splashed across celebrity Instagram feeds and national headlines.
But while they’re helping some people drop significant amounts of weight…
They’re also raising alarm bells in the fitness industry.
So, are these so-called “fat jabs” a gym owner’s nightmare - stealing your members and undercutting your message?
Or could they actually be your best friend in disguise?
Let’s break it down.
⸻
What are fat jabs, and how do they work?
Fat jabs like Ozempic and Wegovy are GLP-1 receptor agonists.
They were originally developed for people with type 2 diabetes, but one of their most noticeable side effects? Significant weight loss.
These injections mimic a hormone that helps regulate appetite and insulin. The result? People feel fuller, eat less, and lose weight — without setting foot in a gym.

The Pros & Cons of Fat Jabs
✅ Pros:
• Clinically proven to help people lose 10–15%+ of their body weight.
• Can help people with obesity-related health issues.
• Reduce food cravings and emotional eating.
• Offer a quick solution in a world full of “quick fixes.”
❌ Cons:
• Nausea, vomiting, and digestion issues are common side effects.
• Can lead to muscle loss if not combined with strength training.
• Long-term use is unclear — what happens when people stop?
• Expensive and often not covered by insurance.
• Doesn’t teach sustainable habits or lifestyle change.

So… are people swapping gym memberships for syringes?
According to a 2024 YouGov survey, over 1 in 10 adults in the UK have tried or are considering weight loss injections.
And among those, a large portion don’t plan on joining a gym.
Why? Because they believe the jab is a shortcut to weight loss — and many see exercise as optional.
That’s a worrying stat for gym owners.
⸻
But here’s the twist: Fat jabs NEED fitness.
Here’s what isn’t being said loudly enough:
💡 Up to 40% of the weight lost on fat jabs can come from MUSCLE.
Which means while the scales might drop… so does strength, metabolism, posture, and long-term health.
That’s where gyms (especially coaching-based gyms) - come back into play.
You have an opportunity to educate and empower these clients.

From competition to collaboration
Instead of seeing fat jabs as the enemy, some smart gym owners are asking:
“How can we support people who are using these jabs and help them get better results?”
Here’s what that might look like:
• Running strength & stability programmes for those losing weight quickly.
• Offering muscle-preservation training to those on jabs.
• Providing accountability and nutrition education that jabs alone don’t deliver.
• Creating a non-judgemental space where clients don’t feel embarrassed about using medication.
⸻
The future? It’s not either/or. It’s both.
Fat jabs are here to stay - but that doesn’t mean gyms are obsolete.
In fact, as more people turn to medication to lose weight, they’ll need expert help to stay healthy.
And that’s where you come in.
