OCS Method was created by highly experienced weight loss doctor with 34 years of lived experience of obesity.
This comprehensive 6-month training combines current science with a clear understanding of what it takes to create lasting change. It gives you deep insight into the mind of a person who is living with obesity, and gives you practical tools and language to overcome the blocks with your client.

Dr. Ritva Mettänen, MD, is an expert in obesity coaching and obesity medicine.
With a decade of clinical experience and 34 years of lived experience with obesity and overweight, she brings rare insight into what weight loss truly takes.
She is known for translating research into clear, practical guidance – without oversimplifying the truth.
Her mission is real, long-term transformation made possible for everyone.
Anyone and everyone already working or planning to work with clients who wish to lose or maintain their weight: Health coaches, personal trainers, and healthcare practitioners who want a science-led, high-standard method for supporting their clients with weight loss and long-term weight management.
Absolutely not. You'd preferably have experience working with clients and a willingness to follow evidence-based practice and scope-of-practice boundaries.
Real-life experience will not give you the same broad scientific knowledge or competence that this training will. If you’re already coaching or training clients, you take ethics seriously, you want structured competency (not “tips and tricks” or second-hand knowledge), and you’re ready to do the work required to support complex cases safely, you are the ideal candidate for the training.
This is not for people looking for quick weight-loss hacks, unverified methods, or a course to “add credentials” without applying the skills. It’s also not for anyone unwilling to work within the scope of practice limits.
Yes, absolutely. If you support clients with weight loss, plateaus, adherence, or long-term maintenance, and want clearer communication, risk awareness, and a coaching structure, this training is exactly for you.
Yes. The program is built to strengthen safety, strategy, communication, and long-term support - especially in the GLP-1 era.
Yes. The focus is not just nutrition - it’s the full complexity of obesity: behavior, stigma, medication realities, red flags, and long-term change support. Many clinicians appreciate the coaching and adherence frameworks.
Yes, if you have a relevant background and/or a clear plan to work with this clientele. You’ll be expected to apply the methods in practice.
No. This certification does not train or authorize prescribing. It trains coaching competence: communication, safety awareness, behavior change support, and working alongside medical care within professional boundaries.
