When choosing between Voy and Second Nature, clinical credibility and specialised experience matter. Second Nature has focused exclusively on weight management since 2017, with NHS partnerships and published research backing our approach.
Voy launched in 2024 as a sub-brand of Manual, a men’s health company known for treating hair loss and erectile dysfunction. While both offer weight-loss injections, only Second Nature brings seven years of specialist expertise.
Important safety information: Weight-loss medications like Mounjaro and Wegovy are prescription-only medicines. This article is for informational purposes only. Always consult with your healthcare provider before starting any new medication or weight-loss programme.

Clinical evidence and NHS partnership
Second Nature: Specialist expertise since 2017
Second Nature has focused exclusively on weight management and behaviour change for over seven years. This specialisation shows in our results.
Our recently published JMIR research demonstrates1:
- 19.1% average weight loss at 12 months for those on medication support
- 77.7% achieved ≥10% weight loss
- 69% reported no side effects by month 12
The NHS has commissioned Second Nature since 2017, with over half of UK health boards using our services. This partnership validates our clinical approach and data security standards.
Voy: New entrant from a men’s health company
Voy launched in 2024 as Manual’s expansion into weight loss. Manual has operated since 2018, focusing on hair loss treatments and erectile dysfunction medications.
While Manual has experience in telemedicine, weight management requires different expertise. Voy cites that users “lost 5 times more weight,” but this comes from customer surveys, not clinical trials.
Key difference: When you need heart surgery, you choose a cardiac specialist, not a general surgeon. The same principle applies to weight management programmes.
Support structure: Specialists vs generalists
Professional qualifications matter
Second Nature provides:
- UK-registered dietitians and nutritionists
- Professionals trained specifically in GLP-1 medications
- Supervised by senior dietitians
- Trained by in-house psychologists on behaviour change coaching
Voy offers:
- “Health coaches” without specified qualifications
- General wellness support approach
- Limited medication-specific expertise
- Unknown supervision structure
Community support proven to improve outcomes
Research shows peer support improves weight-loss maintenance2. Second Nature places you in small groups with others on similar journeys.
These groups provide:
- Shared experiences with medication side effects
- Motivation during challenging periods
- Real-world tips from successful members
- Accountability beyond just your coach
Voy’s individual-only approach misses this crucial element of sustainable weight loss.
Technology and tools
Second Nature’s comprehensive 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
Who should choose each programme?
Choose Second Nature if you:
- Want specialist weight management expertise
- Value NHS-validated approaches
- Prefer registered healthcare professionals
- Benefit from peer support communities
- Seek comprehensive behaviour change
- Want options with or without medication
Consider Voy if you:
- Only need basic medication access
- Prefer newer, less established services
- Don’t want peer group interaction
- Are comfortable with generalist support

Take home message
Choosing between Voy and Second Nature means deciding between a weight-loss specialist and a generalist health company’s new venture.
Second Nature brings seven years of exclusive weight management focus, NHS partnerships, and published clinical evidence. Our registered dietitians provide expert support proven to help 77.7% achieve significant weight loss.
Voy offers basic medication access from a company better known for hair loss treatments. While adequate for simple prescription needs, they lack the specialised expertise for optimal outcomes.
Weight-loss medications are most effective when taken alongside comprehensive support. Investing in specialist care often proves more valuable than saving money with generalist services.
Second Nature's Mounjaro and Wegovy programmes
Second Nature provides Mounjaro or Wegovy as part of our Mounjaro and Wegovy weight-loss programmes.
Why choose Second Nature over other medication providers, assuming you're eligible?
Because peace of mind matters.
We've had the privilege of working with the NHS for over eight years, helping people across the UK take meaningful steps toward a healthier, happier life.
Our programmes are designed to meet people where they are, whether that means support with weight loss through compassionate one-to-one health coaching, or access to the latest weight-loss medications (like Mounjaro and Wegovy) delivered alongside expert care from a multidisciplinary team of doctors, psychologists, dietitians, and personal trainers.
At the heart of everything we do is a simple belief: real, lasting change comes from building better habits, not relying on quick fixes. We're here to support that change every step of the way.
With over a decade of experience, thousands of lives changed, and a long-standing record of delivering programmes used by the NHS, we believe we're the UK's most trusted weight-loss programme.
We hope to offer you something invaluable: peace of mind, and the support you need to take that first step.
