Here's a number that stopped me mid-scroll.
The HSE spent an average of €550,000 a day in 2025 on weight-loss and diabetes injections — Ozempic and Saxenda — for patients on free drugs schemes. That's from figures released to BreakingNews.ie under Freedom of Information. The total since January 2023: €212 million. Around 80,000 people got the injections through free drugs schemes in 2025 alone.
And if you're paying privately? Wegovy launched in Ireland in March 2025 at roughly €220 a month. That's €2,640 a year, out of your own pocket, potentially for years.
First things first: this isn't a go at anyone on the injections
Let's be clear before anything else. Some people genuinely need these medications. For people with type 2 diabetes, Ozempic is a diabetes drug first — that's what the HSE funds it for. For people with significant obesity, GLP-1 medications prescribed by a doctor can be the thing that finally makes progress possible after decades of struggling. If that's you, fair play — you're doing something about it, and that takes more courage than most people give it credit for.
This isn't anti-medication. It's a question about the other side of the equation.
Because here's what the €212 million tells me: an enormous number of Irish people want to lose weight badly enough to inject themselves every week. The demand is real. The struggle is real. The Healthy Ireland Survey 2024 found 56% of us aged 15+ are overweight or obese — 63% of men. (I've compiled all the Irish figures, sources linked, on one page: Ireland Fitness & Obesity Statistics.)
And yet almost nobody was ever actually taught the basics of how fat loss works. Not in school. Not by their GP in a rushed ten-minute appointment. Nowhere.
The national bill behind that number
The injections are the newest line item, not the whole cost. Safefood-funded research by University College Cork put the direct and indirect cost of overweight and obesity in the Republic at €1.13 billion a year. That is the 2012 Safefood/UCC costing and still the most recent full study, so today's real figure is almost certainly higher. Northern Ireland adds an estimated €510 million on top.
How that splits, from the same research:
- 35% direct healthcare: drugs, hospital inpatient and day care, driven mainly by cardiovascular disease, type 2 diabetes, colon cancer, stroke and gallbladder disease.
- 65% indirect: absenteeism, where low back pain is the single biggest driver, and lost productivity from premature death, where coronary heart disease leads.
Worth sitting with: that costing predates the GLP-1 spend entirely. The €550,000 a day is on top of a bill that was already over a billion, and none of it buys anyone the one thing that keeps the result once the prescription stops.
What the injections actually do
In plain English: GLP-1 medications reduce your appetite. You feel full sooner and stay full longer, so you eat less.
That's it. That's the mechanism that matters for weight loss. They make a calorie deficit easier to sustain.
They don't burn fat directly. They don't change your metabolism into a furnace. They get you to eat fewer calories than you burn — which is the same thing every diet that has ever worked does, and the same thing you can do without a prescription.
That's also why so many people regain weight after coming off them: if the appetite control was doing all the work and nothing else changed — no new eating habits, no walking, no strength work, no awareness of what's actually in your food — the old pattern comes straight back.
What losing fat for free actually takes
The unsexy truth is that fat loss runs on four basics, and all four cost nothing.
1. A calorie deficit. Eat slightly fewer calories than your body burns, consistently, and fat comes off. Not a crash diet — a modest, boring, sustainable deficit. Everything else in fat loss is in service of this one thing. If you've never worked out what your body actually burns in a day, our free TDEE calculator does it in about 30 seconds.
2. Enough protein. Protein keeps you full — the same appetite effect the injections are selling, just milder and free. It also protects your muscle while you lose fat, which is what makes the difference between "lost weight" and "look and feel better".
3. Walking. Not a punishing gym programme. Walking. The HSE recommendation is 30 minutes of moderate activity, 5 days a week. Only 41% of us hit that — down from 46% in 2019. It's the cheapest fat-loss tool in existence and most of us are leaving it on the table.
4. Tracking. Not forever — just long enough to see what you're actually eating, because almost everyone underestimates it. A few weeks of honest tracking teaches you more about your own eating than years of guessing. Our free tracker exists for exactly this, no subscription, no catch.
That's the whole system. I've laid it out step by step in Fat Loss Basics — it's free and it always will be.
"If it's that simple, why isn't everyone lean?"
Fair question. Because simple isn't easy.
The basics are boring. They take weeks to show results, and we live in a world engineered to make you eat more — bigger portions, delivery apps, snacks at every till. A weekly injection that switches your appetite off is genuinely easier. Nobody should pretend otherwise.
But easier isn't the same as better for everyone. The medication route has real costs — €220 a month privately, side effects for some people, and the open question of what happens when you stop. The basics route costs nothing and builds habits that stay with you when nothing external is propping you up.
And here's the bit nobody says out loud: the basics are exactly what makes the medication work long-term too. Every sensible clinician says the injections should sit on top of diet and activity changes, not replace them. So whether you're on them or not, you still need the same four fundamentals. There is no version of this where the basics don't matter.
The bit that actually annoys me
We're spending over half a million euro a day treating the end result, and roughly nothing teaching people the basics that would help prevent it. Safefood-funded research put the annual cost of overweight and obesity in the Republic at €1.13 billion — and that estimate is from 2012, before any of this.
Meanwhile "how many calories does my body actually burn" is a question most Irish adults have never been shown how to answer.
I'm not going to fix health policy from a blog. But I can put the basics where anyone can get them for free. That's the whole point of this site.

Read Fat Loss BasicsFrequently Asked Questions
Are weight-loss injections like Ozempic and Wegovy actually free in Ireland?
Only through specific HSE schemes, and even then it's the taxpayer footing the bill. The HSE spent an average of €550,000 a day in 2025 on these injections for patients on free drugs schemes, €212 million since January 2023. If you're paying privately, Wegovy launched in Ireland in March 2025 at roughly €220 a month, around €2,640 a year out of your own pocket.
What do GLP-1 injections like Ozempic actually do?
In plain English, they reduce your appetite. You feel full sooner and stay full longer, so you eat less. That's the mechanism that matters for weight loss. They don't burn fat directly or rev up your metabolism, they just make a calorie deficit easier to stick to.
Why do people regain weight after stopping the injections?
Because if the appetite suppression was doing all the work and nothing else changed, no new eating habits, no walking, no awareness of what you're actually eating, the old pattern comes straight back once the drug stops working. The habits underneath have to be built regardless of whether you're on the injection or not.
Is this article saying people shouldn't use weight-loss injections?
No, this isn't a go at anyone on them. For people with type 2 diabetes or significant obesity, a GLP-1 medication prescribed by a doctor can be exactly the right call, and every sensible clinician says it should sit on top of diet and activity changes, not replace them. This article is about the free side of that equation that gets talked about far less.
What are the free basics that do the same job as the injections?
Four things, and all of them cost nothing: a modest calorie deficit, enough protein to stay full and protect muscle, walking (the HSE guideline is 30 minutes, 5 days a week, only 41% of us hit that), and tracking your food for a couple of honest weeks so you actually know what you're eating. That's the free engine underneath every route to fat loss, injections or not.
