GLP-1 programme · Barcelona and online
The medicine takes away your appetite. What you eat even when you have less appetite, and what happens when you stop it, is what we work on here.
Five-phase programme validated by Juana Mª González, Technical Director (Col. CAT000921) · Updated on 21/09/2026. Your doctor always decides the dose.
Where are you right now?
If you’re starting, have a plan: what to eat when you have very little appetite, and how to look after your muscle from the first week.
We review what you actually eat, help you with nausea or constipation, and measure whether what you lose is fat rather than muscle.
Whatever your doctor’s plan, we prepare in good time: gradual reintroduction, strength work and more frequent appointments during the first few months.
What you tell us
These aren’t patients’ opinions: they’re the questions we hear most often in appointments, and how we answer them.
‘I know lots of people who are injecting themselves. What do you think?’
It’s a medical treatment, not a trend, and it’s prescribed by your doctor. If you take it, our job is to help it work in your favour: to make sure you eat enough, preserve muscle and learn habits that stay with you when you stop taking it.
‘I’ve been told to eat high-protein yoghurts.’
They can help sometimes, but they aren’t a plan. Spread protein across all your meals, using foods you can manage even when your appetite is low: eggs, pulses, fish, meat, dairy or tofu. We give you specific amounts tailored to you.
‘My doctor said I might be able to keep taking it at a low dose afterwards.’
That may be an option, and your doctor decides. Whether you continue or stop, what supports the result is what you’ve learnt about eating and the strength you’ve built while taking it. That’s what we work on with you.
What the scales don't show
Three things we see in appointments that don’t depend on the dose.
When you lose weight quickly while eating very little, some of what you lose is muscle: in studies of these medicines, between a quarter and almost two-fifths of the weight lost. That’s why we measure fat and muscle, not just weight.
Are you losing muscle? Take the quiz →When your appetite is suppressed, it’s easy to miss meals without realising. We see it often: without someone keeping an eye on things, some people end up eating very little. Too little protein, fluid and fibre can lead to tiredness, constipation or hair loss.
Work out the protein you need →When you stop the medication, your hunger returns. Studies show that, on average, more than half the weight lost is regained within a year of stopping. It isn’t your fault: that’s how the treatment works. That’s why we prepare for coming off it from day one.

Each phase lasts as long as you need; the timings are only a guide. Choose a phase to see what we do, what we measure and how often we meet.
Phase 0 · Before you start or when you join
You have your prescription, or you’ve just started, and you have lots of questions.
Phase 1 · Weeks 0 to 16-20
Each dose increase can bring nausea, feeling full very quickly or constipation.
Phase 2 · Months 4 to 12, roughly
You’re losing weight and many people feel more upbeat and more inclined to move. This is the time to make the most of it.
Phase 3 · From month 12-18, roughly
Your weight stabilises and the question comes up: should I carry on, reduce the dose or stop?
Phase 4 · Up to 12 months after stopping
Hunger returns, along with the fear of regaining what you’ve lost. This is the phase when we stay closest to you.
Your doctor always decides the dose and when to increase, reduce or stop it. We work with the dose they prescribe and, if you ask us, we can coordinate with them in writing.
A year from now
This isn’t a promise about kilos. It’s what we work towards with you, phase by phase.
You eat when you’re hungry, without fear. You know what to put on your plate on an ordinary Tuesday, in a restaurant or at a family meal.
You walk upstairs carrying the shopping and notice the difference. You’ve lost fat and looked after your muscle along the way.
What you’ve lost is supported by how you eat, move and rest, not just by a dose.
Whether you’re still taking the medication or have stopped, you know what to do. You make the decision with your doctor, with a plan and without rushing.
To be honest, no one can guarantee that you won’t regain weight. What we can offer is a method with progress measured at every stage, and a team that stays by your side when you stop the medication.
What's included
At in-person appointments, we measure your body composition, not just your weight.
A questionnaire before your first appointment. If needed, psychology support is involved from the outset.
A message or phone call 48–72 hours after each change, when side effects often appear.
You can email us between appointments if anything changes.
If you ask us, we’ll send them a report. Your doctor always decides the dose.
A schedule for reintroducing foods and appointments for when you decide to stop the medication.
Free tools
No appointment, no commitment. If you'd like to go through it together afterwards, we're here.
