Dr Leonard Leng’s Professional Background

Dr Leonard Leng completed his MBBS at the National University of Singapore, where he later read for a Master of Medicine in Family Medicine and a Graduate Diploma in Occupational Medicine. He is a Registered Family Physician with the Family Physicians Accreditation Board (FPAB).

Before moving into family practice, he rotated through internal medicine, emergency medicine, general surgery, orthopaedic surgery, sports medicine and paediatrics across Singapore’s hospital system.

His interest in prevention led to board certification in Lifestyle Medicine with the American College of Lifestyle Medicine. He is a founding member and Vice-President of the Singaporean Society of Lifestyle Medicine, and holds the Basic Obesity Management Accreditation (BOMA) alongside Practical Obesity Management Skills (POMS) certification.

As a Designated Workplace Doctor, he also conducts occupational and workplace health assessments.

Dr Leonard’s Areas of Clinical Focus

Lifestyle Medicine

Evidence-based changes to nutrition, activity, sleep and stress, used as part of treating and preventing chronic conditions rather than as an afterthought to medication — including high blood pressure, diabetes, raised cholesterol and thyroid conditions.

Longevity Medicine

Focused on healthspan — the years lived in good health — through strategies for healthy ageing, rather than lifespan alone. Usually starts with a health screening to set a baseline.

Disease Prevention

Risk assessment aimed at identifying problems early, when there is more that can be done about them — blood tests reviewed at a follow-up consultation, and vaccinations for adults, travel and occupational requirements.

Family Medicine

General primary care for everyday health concerns, plus men’s health and sexual health including STI testing. Couples also attend together for pre-marital screening or fertility assessment.

Obesity Management

BOMA accredited and POMS certified, with an emphasis on approaches a patient can sustain rather than short-term restriction, including medical weight management where clinically appropriate.

Occupational Medicine

Workplace health assessments as a Designated Workplace Doctor, including the statutory examinations required in certain occupations.

Our team includes both female and male doctors — let us know if you have a preference when you book.

Through lifestyle medicine, I help patients prevent disease, improve their health, and extend their healthspan using evidence-based strategies. Whether you’re here for yourself or with your partner, the goal is always sustainable changes that last.
