The GLP-1 Maintenance Guide: keeping weight off after Wegovy or Mounjaro

GLP-1 medications like Wegovy and Mounjaro have changed what is possible for people managing obesity. But there is a question I hear from almost every client at some point: what happens when I stop, or when the dose is reduced?

Maintenance is not a failure of the medication. It is the second half of the journey, and it deserves just as much thought and support as the weight loss phase. This guide is a practical, evidence-based walk-through of what to focus on if you want to protect your progress long term.

1. Expect appetite to return

When medication levels drop, appetite signals come back. This is biology, not weakness. Hunger, food noise and cravings often return within weeks. Plan for it: keep meal structure predictable, protect protein at every meal, and do not let yourself get overly hungry, which is when old patterns tend to return.

2. Protein and fibre are non-negotiable

The single most useful nutritional habit for maintenance is prioritising protein (roughly 1.2 to 1.6 g per kg of body weight, spread across the day) and fibre (30 g target for most adults). Protein helps preserve muscle and manage appetite. Fibre supports fullness, blood sugar and gut health. Between them, they do most of the heavy lifting.

3. Protect muscle deliberately

Weight loss on GLP-1 often includes some loss of lean tissue. In maintenance, muscle matters more than ever: it supports metabolism, strength, energy and long-term health. Two to three strength sessions a week, even short ones, plus adequate protein, make a real difference. You do not need a gym; bodyweight or resistance bands at home are enough to start.

4. Anchor your day around real meals

Grazing tends to creep back when appetite returns. Structured meals help you notice hunger and fullness again, which is a skill you can rebuild. Aim for three meals a day, each built around a palm of protein, a fist of complex carbs, and half a plate of vegetables. Simple, repeatable, flexible.

5. Keep an eye on the number, gently

A common recommendation is to weigh weekly, at the same time, and to act early on trends rather than individual readings. A 2 to 3 kg upward trend over a few weeks is a signal to review habits, not a reason to panic or restrict. Early, small adjustments are much easier than large corrections later.

6. Sleep, stress and alcohol still count

When the medication was doing more of the work, small lifestyle drift often went unnoticed. In maintenance, sleep debt, chronic stress and regular alcohol all pull appetite and cravings in the wrong direction. None of this needs to be perfect. Aim for consistency, not perfection.

7. Plan for the wobble

Life happens. Holidays, illness, work stress and grief all disrupt routines. Maintenance is not about never going off track. It is about noticing sooner and returning to your basics faster: protein, fibre, meals, sleep, movement. The people who maintain weight long term are not the ones with the most willpower. They are the ones with the shortest recovery time.

8. Get support before you need it

The best time to think about maintenance is before you come off the medication, not after weight regain starts. Whether that means working with a nutritional therapist, a coach, or a supportive peer group, having someone to reflect with makes maintenance dramatically easier.
