Daniel O’Shaughnessy is an award-winning nutritionist, Functional Medicine Certified Practitioner and speaker whose work explores the intersection of physiology, psychology and behaviour. His talks focus on the deeper forces that shape mental wellbeing, including stress physiology, identity, culture and the psychological patterns that influence how people relate to their bodies and their health.

Drawing on more than fifteen years of clinical experience, Daniel brings together functional medicine, behavioural insight and lived experience to examine why many modern health struggles persist despite people trying to do everything “right”. His work looks closely at body image, perfectionism, nervous system stress and the cultural pressures that shape self-perception.

Daniel is the author of Letting Go of Perfect: A Gay Man’s Guide to Healing from Body Dysmorphia and The Queer Guide to Nutrition & Lifestyle. His writing explores how shame, identity pressure and the search for control can influence mental health and behaviour, particularly within environments shaped by performance and comparison.

Through his speaking and writing, Daniel encourages audiences to rethink wellbeing beyond optimisation and perfection, helping them understand how physiology, psychology and lived experience interact to shape mental health and long-term wellbeing.

Official Testimonials

“I invited Daniel to speak at our corporate retreats because our clients need wisdom that is practical, clear, and deeply human. Daniel has a rare gift for taking complex ideas about health, identity, stress, and healing and presenting them in a way that is easy to understand and immediately applicable. His talks combine evidence-informed frameworks with lived experience, so the material feels grounded and real, not abstract or esoteric. Daniel makes healing accessible for audiences who typically expect business language and logic, and he consistently receives the highest praise from participants for changing how they think about wellbeing, resilience, and the connection between mind and body. I recommend him without reservation for any corporate event where you want insight that feels both intelligent and deeply human.”
