Daniel O’Shaughnessy

I am a London-based, award-winning nutritionist, Certified Functional Medicine Practitioner, and mindset coach with more than fifteen years of clinical experience, following an earlier career in drug addiction counselling.

My work sits at the intersection of physiology, psychology, and lived experience, shaped by postgraduate training in trauma, psychedelics, and integrative approaches to mental health, and supported by more than four hundred hours of breathwork facilitator training.

Across my career I have been particularly committed to LGBTQ+ health. I am recognised as one of the practitioners pioneering a more holistic and evidence-informed approach in this space, bringing the realities of identity, stress, and cultural pressure into conversations about wellbeing that have often stayed at the surface.

This work shaped my first book, Naked Nutrition, now being rewritten as The Queer Guide to Nutrition and Lifestyle (August 2026), and my second, Letting Go of Perfect: A Gay Man’s Guide to Healing from Body Dysmorphia, which explores body image, shame, and self-worth through the lens of the Gay lived experience.

My approach is informed by my own healing. For years, body dysmorphia and perfectionism were the outward expressions of deeper, long-standing trauma and the pressure to perform strength. The strategies that once helped me cope eventually stopped supporting the life I wanted to lead. Through therapy, functional nutrition, breathwork, and carefully held psychedelic integration, I began to understand how the past lives in the body and how change becomes possible when the nervous system, mind, and physiology are worked with together. That process gave me perspective, humility, and clarity about what real change requires.

All of this guides the way I work now. I support clients to steady their nervous system, understand the patterns behind their symptoms, and rebuild their health in a way that reflects who they are and what they have lived. My background, training, and lived experience sit alongside one another, shaping the space I hold and the conversations I believe health needs to include.
