Naras Lapsys, BSc(Hons), MSc, PhD, APD, ACAAM, ABAAHP
Chief Clinical Officer and Senior Dietitian · Chi Longevity
PhD molecular geneticist turned longevity dietitian, with 20+ years translating metabolic research into food plans
About
Dr. Naras Lapsys, PhD began at Sydney's Garvan Institute of Medical Research, studying the molecular genetics of obesity and insulin resistance in its Metabolism and Diabetes Research Group. After nearly a decade in research, he moved into clinical nutrition, completing an MSc in Nutrition and Dietetics and founding The Body Doctor in Sydney in 2004. He relocated to Singapore in 2018 and joined Chi Longevity as Chief Clinical Officer and Senior Dietitian, bringing molecular genetics, anti-ageing board certifications, and 20+ years of nutrition practice into Chi's programme model.
What to Know
Signature approach
Lapsys reads nutrition through a molecular-genetics lens. Food plans are built from the client's metabolic data, body composition, goals, and practical life rather than a standard diet template. He is comfortable with fasting, caloric restriction, wearables, sleep, and geroprotective compounds, but his public stance is context-first: restriction is not useful if someone is already under-muscled or under-recovered.
What sets them apart
- Research-to-practice arc. PhD molecular genetics and Garvan Institute obesity and insulin-resistance research before clinical nutrition.
- 20+ years in nutrition practice. Founded The Body Doctor in 2004, moved to Singapore in 2018, and joined Chi in 2023.
- Early anti-ageing credentials. ACAAM and ABAAHP board certifications before longevity medicine became mainstream.
- Public educator. Speaker, podcast guest, and media source on nutrition, fasting, sleep, wearables, and healthy ageing.
Before You Book
- Nutrition-led, physician-supported. Lapsys leads nutrition and lifestyle strategy; prescribing and medical diagnosis stay with Chi's physicians.
- Programme-based access. Expect to work with him through a Chi programme rather than a standalone dietitian booking.
- Independent practice also exists. He maintains separate nutrition affiliations in Singapore, so confirm whether you want the Chi programme pathway or his private-practice route.
