When choosing between Second Nature and Morrisons Clinic for weight loss medication, the main difference is how much support you get alongside your medication.
Second Nature combines Mounjaro with support from registered dietitians or nutritionists, building on six years of working with the NHS.
Morrisons Clinic, launched in January 2025, offers quick access to medication through its supermarket partnership, along with basic check-ins from pharmacists.
The choice comes down to two different approaches: learning new habits for lasting change versus getting medication with minimal support and managing the rest yourself.
Both services give you access to effective weight-loss medications, but the level of support, expertise, and planning for life after medication is completely different.
Understanding these differences helps you determine which approach best fits your health goals and the level of guidance you prefer.
The biggest differences include the type of professional support you get, help with planning for after you stop medication, a proven track record, and how much help you receive for changing your eating habits alongside medication.

Core approach differences
The basic philosophy behind these services shapes everything about your experience.
Second Nature: learning habits that last
At Second Nature, we view weight loss medication as a tool that creates the space you need to develop healthy habits that keep the weight off long-term.
Our approach recognises that keeping weight off requires understanding why you gained weight in the first place: the habits, emotions, and situations that influence how you eat.
This means working with registered dietitians or nutritionists who understand both how the medication affects you and the complex relationship between food, emotions, and daily habits.
Our app gives you step-by-step guidance, peer support groups, and practical tools for handling real-world situations.
We know that successful weight management goes far beyond medication. You need skills in meal planning, eating out socially, managing stress without food, and building a healthier relationship with eating.
Morrisons Clinic: quick medication access
Morrisons Clinic focuses on getting you medication quickly and conveniently through their supermarket partnership with Phlo Digital Pharmacy.
Their approach prioritises speed and convenience, letting you complete a short online consultation and get medication delivered within 24 hours. The service includes basic safety monitoring through pharmacist check-ins.
They expect you to manage the lifestyle changes needed for weight loss on your own, providing medication as the main intervention with minimal structured support.
This works well if you prefer managing things yourself and feel confident making dietary and habit changes alongside medication without much guidance.
Clinical credibility & expertise
The level of medical supervision and research backing differs significantly between these services.
Second Nature: NHS-backed approach
Since 2017, the NHS has chosen Second Nature to deliver weight loss and type 2 diabetes programmes across the UK.
Over half of UK NHS Health and Care boards now use our services, showing healthcare professionals trust our approach.
Our results are backed by research published in the British Medical Journal, showing members lose an average of 5.9kg at 12 weeks with 62.5% losing at least 5% of their weight.
Recent research on our medication programme, published in JMIR Formative Research, showed that participants lost an average of 6.5 kg (6.4% of body weight) after 3 months, with 62.5% achieving clinically meaningful weight loss.
Our team includes UK-registered dietitians and nutritionists who specialise in supporting people taking weight-loss medications.
These qualified professionals understand both how medications affect your body and the strategies needed for lasting success.
Morrisons Clinic: pharmacy-based service
Morrisons Clinic works through a partnership with Phlo Digital Pharmacy, a licensed pharmacy that provides medication access with pharmacist supervision.
Their team consists of qualified pharmacists who review online consultations and provide monthly check-ins via email. The service launched in January 2025, so it’s very new without an established track record.
For effectiveness, Morrisons Clinic cites the clinical trial data for the medications themselves (such as Mounjaro’s 20% weight loss in trials) rather than its own programme results.
While pharmacists provide valuable medication expertise, they don’t typically have the specialised training in nutrition habits and behaviour change that registered dietitians and nutritionists offer.
Programme structure & support
Your day-to-day experience using these services is quite different in terms of structure and ongoing guidance.
Second Nature: proper support for changing habits
Our programme is built around proven strategies for changing eating habits, delivered through multiple ways designed to support lasting change.
You get access to UK-registered dietitians and nutritionists who are available five days a week via both group and private chat.
These professionals have specific training in supporting people taking weight-loss medications, understanding both side effect management and optimising nutrition during treatment.
Our custom app includes over 300 recipes designed for people taking weight-loss medications, habit-tracking tools, educational content, and progress monitoring.
You’re placed in small peer support groups with others on similar journeys, creating community and accountability.
The programme prepares you for life after medication from day one, focusing on building habits that will maintain your progress in the long term.
Our approach includes meal planning skills, social eating strategies, and developing a healthy relationship with food and exercise.
Morrisons Clinic: basic monitoring with self-management
Morrisons Clinic provides basic medication management through its pharmacy partnership.
After completing an online consultation, you get monthly check-ins via email from pharmacists who monitor your progress and adjust dosing as needed.
The service includes practical elements, such as free sharps disposal bins, needles, and alcohol wipes, with medication orders.
They offer bundles for 8-week supplies, providing flexibility for those who prefer longer supplies.
Their approach expects you to manage the lifestyle parts of weight loss yourself. While they stress the importance of combining medication with diet and exercise, they don’t provide structured guidance for actually implementing these changes.
This works well if you’re confident in managing your own dietary changes and prefer minimal programme structure alongside your medication.

What you get for your money
While Morrisons Clinic’s medication-only pricing looks much lower, you need to consider what’s included in each service.
Second Nature’s monthly fee covers medication costs plus full support for changing habits, structured education, peer community, and planning for after you stop medication.
Our programme teaches you skills that support long-term weight management beyond medication use.
Morrisons Clinic offers medication access with basic safety monitoring, expecting you to independently develop the lifestyle strategies necessary for maintaining weight loss.
The cost difference reflects the level of support provided. If you want medication with minimal programme structure, Morrisons offers good value.
For comprehensive support in changing habits, Second Nature offers a more rounded package, albeit with higher upfront costs.
Long-term outcomes
The real test of any weight management programme is keeping results that improve your health and quality of life over the years, not just months.
Second Nature: building for lasting results
Our approach focuses on keeping weight off through building habits and developing skills.
Our NHS research shows 6.2kg average weight loss at 12 months, with many participants maintaining results beyond the programme period.
We recognise that medication provides a window of opportunity to establish healthier patterns, but lasting success requires addressing the behaviours and psychological factors that contributed to weight gain initially.
Our programme teaches practical skills like meal planning, navigating social eating, and managing stress without relying on food. These capabilities support weight maintenance long after medication use ends.
User satisfaction reflects this approach, with 4.6/5 stars on Trustpilot from over 7,600 reviews, many highlighting the lasting habit changes developed during the programme.
Morrisons Clinic: medication-focused results
As a newly launched service (January 2025), Morrisons Clinic doesn’t yet have their own results data. Their effectiveness claims reference medication clinical trials showing up to 20% weight loss with tirzepatide.
Their approach expects you to independently develop the lifestyle strategies needed to maintain weight loss after stopping medication. Success depends mainly on personal motivation and self-directed habit change.
The service provides medication access with basic monitoring, but doesn’t include structured support for building the long-term habits typically needed to keep weight off.

At Second Nature, we believe keeping weight off requires more than medication alone. Our programme teaches you to build a healthier relationship with food and your body by understanding habits, rather than relying solely on medication.
If you’re confident in managing lifestyle changes independently and primarily need medication access, Morrisons Clinic offers a convenient, cost-effective solution.
If you want full support for building habits that work long after medication ends, our NHS-backed approach provides the foundation for lasting change.
Remember that successful weight management is ultimately about creating a lifestyle that supports your health for years to come, not just losing weight quickly.
