slimmr vs Second Nature

Jump to: Key differences | NHS partnership & clinical evidence | Programme structure | Support & coaching | Cost comparison | Take home message

When choosing between slimmr and Second Nature for medication-supported weight loss, the most important difference is clinical credibility.

Second Nature has been delivering NHS-commissioned weight-loss services since 2017, with over six years of published clinical outcomes supporting its effectiveness.

In contrast, slimmr launched in 2024 as a newer medication provider focused primarily on drug access with optional add-on support packages.

Both programmes offer weight-loss injections like Mounjaro and Wegovy alongside digital support, but Second Nature’s longer track record and included comprehensive support provides greater peace of mind for patients seeking a clinically-proven approach to sustainable weight loss.

The most significant differences between these programmes are clinical experience, support structure, and value proposition. While slimmr offers competitive medication pricing, Second Nature includes comprehensive behavioural support as standard rather than charging separately for each service.

NHS partnership & clinical evidence

Second Nature’s relationship with the NHS sets it apart as the most clinically trusted medication-supported weight loss programme in the UK.

Since 2017, the NHS has commissioned Second Nature to deliver weight loss and type 2 diabetes programmes across the UK, with over half of all UK NHS Health and Care boards using our services.

This NHS partnership ensures robust clinical oversight, data security, and evidence-based approaches that have been tested at scale.

Our published clinical results show participants lost an average of 5.9kg at 12 weeks, with 62.5% achieving at least 5% weight loss by 3 months. For our medication-supported programme, participants lost an average of 6.5kg after 12 weeks.

The National Institute of Health and Care Excellence (NICE) recently announced that Wegovy would be available via digital weight management services provided by Second Nature and three other companies supporting the NHS.

slimmr operates as a newer service without NHS partnerships or published programme-specific clinical data. While they reference clinical trials of the medications themselves, there are no independent studies evaluating slimmr’s specific approach or outcomes.

slimmr was founded by medical professionals with NHS experience, but the service itself hasn’t established the institutional partnerships or published clinical evidence that Second Nature provides.

Programme structure

Both programmes offer medication access with digital support, but their approaches differ significantly in structure and comprehensiveness.

Second Nature’s integrated approach

Our programme is built on a foundation of behavioural science developed through years of NHS collaboration. The approach includes:

• Building sustainable habits alongside medication support from day one
• Non-restrictive nutrition philosophy that doesn’t require calorie counting
• Structured educational content based on clinical evidence
• Comprehensive app with food journals, recipes, and progress tracking
• Both medication-supported and non-medication options
• Focus on post-medication planning from the start

slimmr’s medication-first model

slimmr positions itself as a medication provider with basic included support:

• Primary emphasis on GLP-1 medications as the main intervention
• Included weekly exercise classes and CBT videos
• Some 1:1 coaching and prescriber support included
• Optional add-on packages for specialist dietitian or psychology support
• No medication-free programme option

The key difference lies in philosophy. Second Nature emphasises habit formation and behavioural change from day one, preparing you for sustainable results even after medication use ends. slimmr focuses primarily on medication provision with supportive elements.

Support & coaching

The quality and accessibility of support can make all the difference when taking weight-loss medications like Mounjaro or Wegovy.

Comprehensive included support at Second Nature

Second Nature provides access to UK-registered dietitians and nutritionists who specialise in supporting members on weight-loss injections as part of your standard programme cost.

Our health coaches are available five days a week via both group and private chat, receiving specific training in side effect management and medication-supported weight loss.

We place you in a small group with others on similar journeys, creating a supportive community where you can share experiences and strategies.

The programme is designed with post-medication life in mind, including focus on sustainable habit formation, personalised transition plans for maintaining results after medication, and ongoing access to support resources even after completing the programme.

slimmr’s tiered support model

slimmr includes basic support with their medication service:

• Weekly exercise classes with a qualified trainer
• CBT videos focusing on psychological aspects of weight loss
• Basic 1:1 coaching and prescriber support included
• Regular patient support calls from their team

However, specialist support requires additional payment:

• Individual dietitian sessions: £150 per session
• Dietitian support group: £175
• Individual psychotherapy: Cost varies (£840 for six sessions mentioned in some sources)

slimmr’s approach allows you to choose your level of support, but this means accessing comprehensive guidance requires significant additional investment beyond the medication cost.

Cost comparison

Understanding the total investment helps determine which programme offers better value for your specific needs.

Second Nature pricing:

• Mounjaro programme: £229-£299 monthly (increases with higher doses)
• Includes all medication, comprehensive app, registered dietitian/nutritionist support, group coaching, and educational content
• £100 discount on first month

slimmr pricing:

• Wegovy: £189-£299 monthly (increases with dose)
• Mounjaro: £189-£249 monthly (increases with dose)
• Includes medication, weekly exercise classes, CBT videos, basic coaching, and prescriber support
• Additional specialist support costs extra

Total cost comparison for comprehensive support:

If you want the equivalent level of professional guidance at slimmr, the monthly costs would be:

• Medication: £189-£299
• Plus individual dietitian support: £150+ per session
• Plus psychology support: £140+ per session (based on six-session packages)

This means accessing specialist nutrition and psychology support at slimmr could cost £400-600+ monthly, significantly more than Second Nature’s all-inclusive approach.

Patient satisfaction:

• Second Nature: 4.6/5 from >7,600 Trustpilot reviews
• slimmr: 4.8/5 from >100 reviews

While both services receive excellent reviews, Second Nature’s rating is based on over 75 times more reviews, demonstrating consistent quality at scale.

Take home message

Weight-loss medications like Mounjaro and Wegovy can be transformative when paired with the right support programme. They help silence food-related thoughts and provide the mental space to develop sustainable habits for long-term success.

Choose Second Nature if you value:

• Clinical confidence through NHS partnership and published outcomes
• Comprehensive support included as standard
• Experienced registered dietitians with extensive medication expertise
• Proven results with transparent outcome data
• Post-medication planning and sustainable habit formation
• Consistent quality demonstrated across thousands of patients

Choose slimmr if you prefer:

• Lower initial medication costs
• Flexibility to add specialist support as needed
• Newer service with responsive customer support
• Basic included support with optional upgrades

The fundamental difference lies in approach: Second Nature provides comprehensive support as standard, while slimmr operates on a tiered model where specialist guidance costs extra.

For most people seeking medication-supported weight loss, Second Nature’s inclusive approach offers better value and peace of mind.

The combination of NHS validation, clinical evidence, and comprehensive support provides the foundation for lasting success.

If you’re confident in managing your weight loss journey independently and primarily need medication access with basic support, slimmr’s tiered approach may suit your preferences.

Remember that the ultimate goal isn’t just weight loss, but creating a healthier relationship with food and your body that supports long-term wellbeing. This requires more than medication alone.
