Juniper vs Second Nature

Jump to: Quick comparison | Clinical evidence | Support and coaching | Who should choose each | FAQs | Take home message

When choosing between Juniper and Second Nature for medication-supported weight loss, the key differences come down to clinical background, UK healthcare integration, and the type of support you receive alongside medication.

Second Nature has focused exclusively on weight management since 2017 and is NHS-commissioned across 43 ICBs and Health Boards. Our 12-month outcomes are published in JMIR Formative Research¹.

Juniper is a digital weight-loss programme owned by Eucalyptus, an Australian health technology company. Since launching in the UK in 2022, Juniper has grown to 150,000 members globally and has published peer-reviewed UK outcomes data in the Journal of Diabetes, Obesity and Metabolism².

Both services prescribe the same medications. The differences lie in clinical track record, how support is delivered, and the programme’s philosophy on long-term weight maintenance.

This guide was written by Second Nature, so it naturally reflects our perspective, but we’ve aimed to present Juniper’s strengths and limitations as fairly as possible.

Juniper vs Second Nature: quick comparison

Clinical evidence and NHS partnership

Second Nature: NHS-commissioned, with published 12-month outcomes

Second Nature has focused exclusively on weight management and behaviour change for over eight years. The NHS has commissioned our programmes since 2017, with 43 ICBs and Health Boards across the UK using our services to support over 250,000 patients.

Our published research in JMIR Formative Research shows specific outcomes for our medication-supported programme¹:

• 19.1% average weight loss at 12 months
• 77.7% achieved at least 10% weight loss
• 69% reported no side effects by month 12

Separately, NHS England’s evaluation of the Digital Weight Management Programme found that Second Nature achieved substantially higher weight loss compared to other providers at 12 months³. This is independent validation from the NHS itself, not our own marketing.

Juniper: peer-reviewed UK outcomes at shorter timeframes

Juniper has invested meaningfully in clinical research through its parent company Eucalyptus. Their UK-specific study, published in the peer-reviewed Journal of Diabetes, Obesity and Metabolism, reported²:

• 10.73% average weight loss at 5 months
• 82% achieved at least 5% weight loss
• 52% achieved at least 10% weight loss

Juniper has also published a separate study on tirzepatide (Mounjaro) outcomes in Telemedicine Reports, showing 13.79% average weight loss in 16 weeks among their UK patients.

It’s worth noting that these are studies at different timeframes, so a direct comparison with Second Nature’s 12-month data isn’t straightforward.

What we can say is that both programmes have committed to publishing their outcomes in peer-reviewed journals, which is more than many competitors in this space can claim.

Juniper also has a randomised controlled trial (RCT) underway, with its protocol published in Diabetes, Obesity and Metabolism. If completed and published, this would add a higher level of evidence to their clinical data.

The key research difference is that Second Nature’s data covers a full 12 months, which gives a clearer picture of long-term weight loss and side-effect profiles.

Second Nature also benefits from independent NHS validation through the DWMP evaluation, rather than relying solely on company-funded research.

Support and coaching

Second Nature: registered dietitians and structured behaviour change

Second Nature provides UK-registered dietitians and nutritionists, available five days a week through both group and private messaging. These professionals are:

• Registered with the Health and Care Professions Council (HCPC) or the Association for Nutrition (AfN)
• Trained specifically in GLP-1 medication support
• Supervised by senior dietitians
• Supported by in-house psychologists on behaviour change coaching

You’re also placed in a small peer group with others on similar programmes. Research consistently shows that peer support improves weight-loss maintenance⁴, and this community element is built into every Second Nature membership.

Our programme follows the COM-B model (Capability, Opportunity, Motivation, Behaviour)⁵ and runs across four phases: Core, Grow, Maintain, and Sustain. This structured approach is designed to help you build habits that last beyond medication, which matters because research shows around two-thirds of people regain weight within a year of stopping GLP-1 medication without behaviour change support⁶.

Second Nature’s app includes:

• 300+ recipes designed for weight-loss medications
• Food and mood journals identifying patterns
• Daily educational content (audio or written)
• Habit tracking with behavioural insights
• Medication management with side-effect support

Juniper: women-focused coaching with strength and nutrition

Juniper takes a different approach, with a programme specifically designed around women’s weight loss. Their support model includes:

• Access to health coaches, dietitians, and nutritionists
• Unlimited follow-up consultations with pharmacist prescribers
• An AI health companion (‘June’) for day-to-day questions about nutrition, exercise, and side effects
• A structured coaching course designed by physiotherapists and dietitians
• A private Facebook community for peer support

Juniper’s distinctive focus is on muscle maintenance during weight loss, with a high-protein nutrition philosophy and strength training programme built into their app. This is a genuine differentiator; preserving lean muscle mass is an important consideration during medication-supported weight loss, and Juniper has made it central to their programme design.

Juniper claims to be the ‘only medicated weight loss programme focused on fat loss and muscle maintenance’, and their coaching course includes zone 2 cardio and low-impact strength exercises.

Their own adherence study found that the average Juniper patient stays on the programme for about six months (183 days), with cost being the most common reason for discontinuation (38.7%).

The main difference in support quality comes down to the professional framework. Second Nature’s dietitians are individually registered with UK regulatory bodies (HCPC or AfN), which provides a clear, verifiable standard of clinical expertise.

Juniper’s team includes dietitians and nutritionists, but the specific regulatory registrations and qualifications of their coaching staff are not as clearly detailed in their public-facing materials.

Frequently asked questions

Is Juniper or Second Nature better for Mounjaro?

Both services prescribe Mounjaro and include clinical monitoring alongside the medication. The difference is in the support that comes with it.

Second Nature provides registered dietitians trained in GLP-1 medications, a structured four-phase behaviour change programme, and small peer support groups. Our published research shows 77.7% of participants achieved at least 10% weight loss at 12 months¹.

Juniper includes health coaching, unlimited prescriber consultations, and a focus on high-protein nutrition with strength training for muscle maintenance.

Their published UK data covers shorter timeframes (5 months), but shows strong early outcomes². If preserving muscle mass is a top priority for you, Juniper’s approach may be particularly appealing.

Does Juniper have peer-reviewed research?

Yes. Juniper has published UK-specific outcomes data in the Journal of Diabetes, Obesity and Metabolism², which is a respected peer-reviewed journal. This study reported 10.73% average weight loss at 5 months among UK patients.

They’ve also published a tirzepatide-specific study in Telemedicine Reports, and their parent company Eucalyptus claims over 20 peer-reviewed publications globally. Additionally, Juniper has an RCT underway that could provide higher-quality evidence in future.

Second Nature’s published research covers a longer 12-month timeframe and is supplemented by independent NHS validation through the Digital Weight Management Programme evaluation³. The distinction is in the duration of follow-up and the independent validation rather than research quality.

Is Juniper available on the NHS?

No. Juniper is a private programme with no NHS commissioning or partnerships. Second Nature has been NHS-commissioned since 2017, with 43 ICBs and Health Boards across the UK using our services.

This NHS relationship reflects confidence in our clinical approach, governance standards, and data security. It’s worth noting that NHS commissioning is not a requirement to prescribe weight-loss medications safely; it’s an additional layer of institutional validation that indicates a programme has met rigorous public healthcare standards.

Is Juniper only for women?

Juniper is primarily designed as a women-focused weight-loss programme. Their marketing, coaching content, and community are built around women’s health concerns, including menopause-related weight gain.

Second Nature’s programme is open to all adults, with support from dietitians who tailor advice to individual needs regardless of gender. If you’re looking for a programme that isn’t gender-specific, Second Nature may be a better fit.

Can I switch from Juniper to Second Nature?

Yes. We’ll review your medical history and current medication to ensure a safe transition. A 7-day gap between your last Juniper prescription and your first Second Nature prescription is usually recommended.

Many members join Second Nature after starting with other providers, often seeking more structured behaviour change support alongside their medication. Our dietitians will work with you to continue your progress without disruption.

Which has better customer reviews?

Both services have strong Trustpilot ratings. Juniper has 4.5/5 from over 9,300 reviews, while Second Nature has 4.5/5 from over 7,800 reviews.

Juniper’s higher review volume reflects its larger global membership base and rapid growth since entering the UK market. Second Nature’s reviews have been built consistently over eight years of operation.

Both ratings suggest genuine member satisfaction, and it’s worth reading recent reviews on both platforms to get a feel for the specific experiences that matter most to you.

Is Juniper an Australian company?

Juniper is owned by Eucalyptus, an Australian digital health company that operates across Australia, the UK, Germany, and Japan. Juniper launched in the UK in 2022 and is registered with the Care Quality Commission (CQC) and the General Pharmaceutical Council (GPhC).

While Juniper’s parent company is Australian, its UK operations are regulated by UK bodies, and its published UK research uses data from UK-based patients. Second Nature, by contrast, was founded in the UK and has focused exclusively on UK patients and NHS partnerships since 2017.

Does Juniper offer a money-back guarantee?

Yes. Juniper offers a 25-day money-back guarantee on your first order. If you’re not satisfied for any reason within the first 25 days of receiving your first delivery, you can cancel for a full refund (subject to their terms and conditions).

Second Nature does not offer a money-back guarantee. Our confidence comes from NHS-validated outcomes, published 12-month clinical research, and eight years of results demonstrating the effectiveness of our approach.

Take home message

Second Nature and Juniper both prescribe effective weight-loss medications at broadly comparable prices. Both have published peer-reviewed UK outcomes data, and both have strong Trustpilot ratings from thousands of members. The choice comes down to what matters most to you.

Second Nature brings eight years of specialist weight management experience, NHS commissioning across 43 health boards, the longest published outcome data (12 months), and support from individually registered dietitians.

Our structured behaviour change programme is specifically designed to help you maintain results after medication, supported by evidence that most people regain weight without this kind of support⁶.

Juniper has built significant scale quickly (150,000 global members), offers a women-focused programme with a distinctive emphasis on muscle maintenance and strength training, and provides AI-powered tools alongside coaching. Their published UK research covers shorter timeframes but demonstrates strong early outcomes, and an RCT is underway.

If NHS validation, longer-term evidence, and structured behaviour change are your priorities, Second Nature is likely the better fit. If you prefer a women-focused programme with a focus on muscle maintenance and app-first engagement, Juniper may suit you better.
