Hello, I’m Natalie

Natalie Hayllar is an Accredited Practising Dietitian (APD) and the founder of Santé Logic, offering one-on-one nutrition consultations alongside food, nutrition and communications consulting for organisations.

Her clinical work focuses on general nutrition counselling, helping people navigate the often-confusing world of food with clarity, confidence and practicality. Natalie works across a range of needs, with specialist interests in women’s health (including peri- and menopause), nutrition support during cancer treatment and recovery, lifestyle medicine and sports nutrition. Her approach is evidence-based, compassionate and realistic, supporting sustainable change that fits real lives.

Natalie blends nutrition science with culinary insight, food culture and behaviour change, recognising that what we eat is shaped not just by health needs, but by habits, emotions, social connection and enjoyment. Early in her career, she worked as a clinical dietitian in oncology at St George Hospital in Kogarah — an experience that continues to inform her empathetic, practical approach to cancer nutrition support.

Alongside clinical practice, Natalie brings more than two decades of experience in food and nutrition communications, strategy and consulting. She has worked across FMCG, agency, media, publishing and not-for-profit sectors, helping organisations translate complex nutrition science into clear, credible and engaging communication.

Natalie has completed advanced studies in Culinary Nutrition at Australian Catholic University (ACU), including immersive study in Rome exploring food culture and conviviality. She also holds qualifications in nutrition and dietetics, psychology and marketing, positioning her at the intersection of health, behaviour and food communication.

Outside of work, Natalie is a mother of two teenage boys, a first degree black belt in Taekwondo and a passionate advocate for sports nutrition in martial arts. She balances clinical work, consulting and creative projects with time in the dojo, travel and a lifelong love of food and culture..

Santé = “to your health”

A little “toast” to your personal and professional brand health, and reflecting an absolute love for French culture and their approach to food and health.

Logic = “sound reasoning”

The method behind the madness, the theory behind the practice. The science and rigour, the marketing process and the substantiated science to support the claims.

Natalie has spent more than 30 years studying and working across psychology, nutrition and business. She is committed to ongoing professional development and has recently completed advanced training in culinary nutrition and sports nutrition to ensure her work remains current, practical and evidence-based.

Her approach blends nutrition science with behaviour change, food culture and real-world application — supporting individuals and organisations with clarity, confidence and care.
