Life After Mounjaro: What's Changed, What We Now Know, and How to Maintain the Weight Loss for Good

A year ago, I wrote about the challenge of coming off Mounjaro and other GLP-1 weight loss medications, and what women in midlife need to do to hold onto their results – you can read the blog here. Since then, this topic has exploded – in the media, in GP surgeries, and in my own practice. So it felt like exactly the right time to revisit it with fresh eyes and a significant amount of new evidence.

If you’re currently on Mounjaro, Ozempic, Wegovy, or another GLP-1 medication – or you’re planning to come off one – this post is for you.

Mounjaro is one of the most popular GLP-1 medications currently available

What’s Changed in the Last Year?

The weight regain reality is now better understood

A 2026 study confirmed that people regain approximately 0.8kg per month after stopping GLP-1 medication, with most returning to their pre-treatment weight within 18 months without support. That’s a sobering statistic, but it comes with an important caveat.

Research also shows that around 25% of the weight lost can be sustained long-term, and that regain after medication is around four times faster than after behavioural programmes. The reason is straightforward: GLP-1s suppress your appetite for you. When you stop, that support ends. If you haven’t built the habits to replace it, your body defaults back to what it knows.

The NHS landscape has shifted significantly

A 2026 government obesity strategy has introduced financial incentives for GPs to manage weight loss medication within local surgeries, making these drugs more accessible. However, a British Medical Journal investigation found that one in five local areas still lacks a functional NHS pathway. An £85 million programme co-funded by the government and Eli Lilly is expanding access through community pharmacies and digital health platforms. More access is welcome – but more access without structured nutritional support is still a concern.

A new oral medication is now available (but not on the NHS)

Orforglipron (Foundayo) was approved by the MHRA in August 2026 as a daily pill to help maintain weight loss after stopping GLP-1 injections. Early trial data showed it helped people maintain 75-79% of their weight loss, compared to 38% in those taking a placebo. While it’s not yet available on the NHS, its approval signals that this category of medication is here to stay, but it also underlines why building genuine nutritional habits matters so much. Because medication alone, whether injections or pills, doesn’t address the underlying relationship with food.

HRT and Mounjaro together – a significant new finding

A landmark study published in The Lancet Obstetrics, Gynaecology & Women’s Health in January 2026 found that postmenopausal women using both tirzepatide (Mounjaro) and hormone therapy lost around 35% more weight than those on Mounjaro alone – 17% vs 14% of body weight, with nearly half achieving 20% or more weight loss. This is the first major study to look at this combination, and it’s genuinely exciting for women navigating both menopause and weight management. If you’re on HRT and considering GLP-1 medication, or vice versa, it’s worth discussing this with your doctor.

⚠️ Important safety note for women on HRT: The British Menopause Society published guidance in April 2025 recommending that women using GLP-1 injections alongside HRT should consider switching from oral progesterone to a non-oral form – a patch, gel, or the Mirena coil – because GLP-1 medications slow digestion and may reduce the absorption of oral progesterone. Please do discuss this with your doctor or menopause specialist if this applies to you.

Why Midlife Women Face a Particular Challenge

Perimenopause and menopause change the rules of weight management in ways that go far beyond appetite. Declining oestrogen affects where fat is stored – hello, muffin top – and how quickly the metabolism operates. Sleep disruption, stress, and the hormonal rollercoaster all interact with hunger signals and food choices in ways that no medication fully addresses.

Mounjaro works by mimicking two hormones – GLP-1 and GIP – that regulate blood sugar and appetite. It does this very effectively. But it doesn’t change your relationship with food, your meal planning habits, your ability to read hunger cues, or your understanding of what your body actually needs to thrive in midlife. That’s the gap that nutrition coaching fills.

What to Focus On When Coming Off GLP-1 Medication

The core advice hasn’t changed, but I’d now emphasise a few things more strongly than I did a year ago:

Start before you stop

The best time to build nutritional habits is while you’re still on the medication – when your appetite is reduced and you have the mental space to focus on food quality rather than quantity. Don’t wait until you’ve stopped to think about what comes next.

Protein is non-negotiable

Aim for around 30g at every meal. This is the single most important nutritional lever for maintaining muscle mass, managing hunger, and stabilising blood sugar – all of which are particularly important in midlife. Think eggs, fish, chicken, Greek yoghurt, legumes, and good quality protein powders if needed.

Blood sugar management becomes your main job

Without the medication keeping appetite in check, blood sugar swings can drive cravings quickly. Focus on low-GI carbohydrates – oats, sweet potatoes, brown rice, quinoa – eat regularly, and pair carbohydrates with protein and healthy fats at every meal.

Build in accountability

Research is clear that structured support dramatically improves outcomes after stopping GLP-1 medication. NICE recommends at least a year of support – and that guidance stands. Whether that’s a nutrition coach, a GP, a structured programme, or a combination, don’t try to navigate this alone.

Watch for emotional eating patterns

GLP-1 medications have a quietening effect on "food noise" – the constant background hum of thinking about food. When that effect lifts, it can feel like a wave. This is normal, and it’s worth being prepared for it rather than surprised by it.

Focus on high protein, low GI-carbs and plenty of fibre to keep you feeling fuller between meals

My Approach: Before, During and After Mounjaro Weight Loss Medication

I work with women at every stage of this weight loss medication journey – but particularly those who are currently on it and want to build solid habits alongside it – and those who have stopped and want to protect their results.

Deborah, one of my clients, started working with me while still on Mounjaro, and found that having a nutrition plan in place gave her confidence about what comes next:

“I’m so glad I reached out for support before coming off Mounjaro. Having a personalised nutrition plan in place makes me feel confident about keeping the weight off for good. Working with Carolyn while still on Mounjaro is helping me build new habits I know will last.”Deborah, 60

That’s the approach I’d recommend to anyone: don’t wait until you’ve stopped to start building the foundation.

A Final Thought

Coming off weight loss medication is not the end of your journey, it’s a transition to a new chapter. The medication does an important job, but it was never designed to be the whole answer. The women who keep the weight off are the ones who use the time on medication to build something lasting: a way of eating that nourishes them, a relationship with food that isn’t driven by restriction, and the knowledge and confidence to manage midlife on their own terms.
