Obesity Coaching Standard™
A complete solution that turns your biggest retention problem into your most profitable service line.
The Biggest Untapped Business Opportunity
GLP-1 medications are reshaping the fitness industry. 1 in 8 US adults is already using them, with 39 more in development. These clients are walking into your gym right now — motivated, paying, and looking for support. But most gyms have nothing structured to offer them.
Without a successful framework, they churn. With the wrong advice, they become a liability. And every one who leaves takes their subscription, their referrals, and their loyalty with them.
GLP-1 users and metabolically complex members exist in enormous numbers. They just haven't found a gym that speaks their language or provides them the right solution.
This is not a pricing problem. It is not solved by better equipment, AI, or cheaper memberships. It is a competence problem, a language problem, and a business framework problem — all at once.
A 10-location gym chain with 10,000 members that improves retention by 20%, attracts 2% new clients through refined marketing, and moves 5% of members to a health subscription generates £644,400 in additional annual revenue.
Year two ROI: 6.1x.
The gym that figures out how to offer coherent, structured support to these clients with consistently good results will not have a retention problem.
It will have a waiting list.

OCS™ - The Complete System
OCS is a turnkey system that gives your business a new service line, a new client segment, and the trained staff to deliver both. It's built on a highly successful clinical framework — developed and tested by Dr. Ritva Mettänen, an obesity medicine doctor, in a clinical setting for nearly a decade — and it's designed to make your business money from month one.
It's built around a new health subscription revenue stream, retention improvement, increasing staff knowledge and confidence, risk mitigation, and client safety.
At its core is a 6-month competency-based online certification that trains your fitness professionals to support GLP-1 users and metabolically complex clients safely, ethically, and effectively — from the first session through long-term maintenance.
What makes OCS unique is not just its depth. It is the first solution that gives both the business and a personal trainer a ready-to-implement coaching and business framework and a product rooted in your success and your client's success.
Your certified professionals will understand not just the science of weight loss and metabolic health, but the minds, hormones, history, and shame of these clients.
That understanding is the difference between a member who leaves after three months and one who stays for years — and sends their friends.
Enterprise Licensing — A New Revenue Stream
Your gym already monetises memberships, personal training, and supplements. OCS adds a fourth: a structured health subscription service for the fastest-growing client segment in fitness — GLP-1 users, metabolically complex members, perimenopausal women, and the millions who haven't joined a gym yet because no gym has spoken their language.
OCS enterprise licensing gives your organisation the complete system to build and sell this service: the certification trains your team to deliver it safely, the business framework shows you how to structure and price it, and the marketing language brings the right clients through the door.
Every enterprise licence includes
OCS certification for your team — your fitness professionals complete the full 6-month program and receive the Obesity Coaching Standard credential upon meeting the competency threshold.
Marketing language framework — ready-to-use language that speaks to the clients you are now equipped to serve. The overweight, the hormonally complex, the GLP-1 user, the 40+ woman who has never felt like the gym was for her, the 50-year-old man who just got his first hypertension diagnosis.
Customer journey framework — a structured and detailed pathway from first contact to long-term health subscription membership. Your team knows exactly how to welcome, support, and retain these clients from day one.
Foundational Awareness Module — a short, but critical training for every client-facing member of your staff that sets the minimum standard for safe, respectful interaction with clients living with obesity or using weight loss medication.
Coming soon: Client-facing health guidance app — clinical-grade content on nutrition, sleep, recovery, hormonal health, and weight management, white-labelled for your gym. Currently in development - available to early enterprise clients.
Licensing is structured per location and scales with your organisation.
The framework is designed to adapt to your market — including local regulatory context, cultural considerations, and client demographics.
Pricing is available on request.
Annual licence renewal and recertification are separate costs, tailored to your organisation.
Enterprise clients also have access to optional additional services:
Business consultations — strategic advisory sessions to help your organisation implement the OCS framework, build customer pathways, refine your service model, and maximise results.
Staff training days — on-site or remote training sessions for your wider team, beyond the certified professionals.

Your Instructor
Dr. Ritva Mettänen, MD
Obesity Medicine Doctor | Founder
With nearly a decade of clinical experience and 34 years of lived experience with obesity, Dr. Ritva brings a rare insight into what it takes to create long-term metabolic health and true results in weight loss.
That combination is why the framework she's developed works - a framework with a long-term patient adherence rate consistently close to 100%, at a time when research shows most patients discontinue treatment within two years.
She doesn't just understand the science. She understands the client perspective deeply: the resistance, the shame, the turning points, and what makes clients return year after year. OCS is her way to make that framework available beyond her own practice.
She is known for translating complex clinical science into guidance that professionals can use immediately, without oversimplifying the truth.
Built For Fitness & Wellness Operators
OCS scales with your organisation. Whether you're certifying five trainers or fifty across multiple locations, the licensing model is structured per site with cohort scheduling, progress tracking, and ongoing support built in.
You get a standardised service across every location — same quality, same language, same client experience.
The Opportunity You're Losing
Every month, your gym is losing the clients who would have stayed the longest and paid the most — if someone on your team had known how to serve them.
OCS gives you the trained staff, the service framework, and the revenue model to stop that loss and turn it into growth.
OCA partners with fitness and wellness operators globally, currently working with businesses across the UK and Middle East.
