Dr. Katarina Melzer is the Founder and Principal Consultant of Equiliberty Consulting and an accomplished body weight regulation expert, with a scientific background in physiology and nutrition. With over 20 years of experience as a scientist and lecturer, she brings a multi-dimensional approach to health promotion and body weight regulation. While most specialists focus strictly on diet or exercise alone, Dr. Melzer unifies both under a single framework — connecting the mechanics of energy intake (nutrition), energy expenditure (physical activity), and the emotional drivers that shape human choices.
Her career spans high-impact clinical research, national leadership in nutrition and sports science, and humanitarian fieldwork on the ground:
- Clinical Education & Leadership — Faculty Member for the European Society for Clinical Nutrition and Metabolism (ESPEN). From 2010 to 2025, she chaired the ESPEN Life-Long Learning (LLL) module on Nutrition and Physical Activity, directing its organizational framework, designing its curriculum, and delivering key scientific presentations.
- National Research & Education — Former Head of Unit for Physical Activity in Children, and later Head of Unit for Nutrition and Energy Metabolism, at the Swiss Federal Institute of Sports. She directed national research initiatives and led both the core Nutrition course and the Health Prevention through Physical Activity and Sports course.
- Clinical Trials — Managed complex metabolic and nutritional studies at the University Hospitals of Geneva (HUG), and the Universities of Geneva (UNIGE) and Lausanne (UNIL).
- Humanitarian Fieldwork — Led nutritional assessments for the International Committee of the Red Cross (ICRC) in rural Ethiopia.
Recognizing that vital scientific breakthroughs often remain confined to academic circles rather than reaching everyday health practices, Dr. Melzer founded Equiliberty Consulting to bridge that divide. Through this platform, she translates complex research into practical strategies — advocating for a holistic, systemic approach where nutrition, physical activity, and emotional drivers are treated as one interconnected system, not isolated factors. As a trusted expert and thought leader, she extends this work across educational settings and media platforms through expert commentary, podcast appearances, and public-facing content.
Dr. Melzer holds a Ph.D. in Life Sciences (Physiology) with Highest Distinction from the University of Lausanne, Switzerland, along with Master’s degrees in Nutrition from the American University of Beirut and Food Technology from the University of Belgrade.
