Specialist Plastic Surgeon

Dr Rohit Kumar

MBBS · MMedSci (Burns) · FRACS (Plas) · ANZBCPS Board Certified

Dr Rohit Kumar is a Fellow of the Royal Australasian College of Surgeons (FRACS) in Plastic and Reconstructive Surgery, practising in Sydney's Western suburbs across clinics at Westmead, Penrith and Orange NSW.

His practice has a strong focus on body contouring after significant weight loss — a field that demands not just surgical skill, but a deep understanding of the physical and emotional journey patients have been through before they sit across from him in consultation. Whether the weight was lost through GLP-1 medications, bariatric surgery, or years of disciplined diet and exercise, the commitment behind it is the same — and the final stage needs the same level of care.

International patients from the Pacific region (Fiji, PNG), the Middle East and South Asia are welcome at Dr Kumar's practice. Consultations are available via video for international and regional patients prior to in-person assessment.

Accredited Practising Dietitian

Amy Kellner

APD · The Cosmetic Dietitian

Amy Kellner is an Accredited Practising Dietitian (APD) operating under her brand The Cosmetic Dietitian — a practice specifically focused on the nutritional aspects of cosmetic and body contouring, GLP-1 medication management, and the dietary needs of patients throughout the weight loss journey.

Amy's scope within My Weight Loss Journey covers the nutritional arc that runs alongside the surgical one — from the pre-operative optimisation of protein and micronutrient status that determines wound healing and recovery outcomes, through the post-operative dietary management that protects against muscle loss and nutritional deficiency, to the long-term lifestyle strategy that ensures results are maintained.

Consultations with Amy are available nationally via Telehealth, as well as in-person where available. Amy works closely with Dr Kumar's team to ensure patients approaching body contouring are nutritionally prepared and that the two clinical approaches are genuinely integrated.

Areas of focus

  • Pre-surgical nutrition optimisation — protein loading, micronutrient correction, liver reduction diet
  • GLP-1 medication dietary management — protein preservation, muscle protection, appetite management
  • Post-bariatric surgery nutrition — lifelong supplementation, deficiency monitoring, food tolerance
  • Post-body contouring recovery nutrition — wound healing, collagen synthesis support
  • Body composition — working with DEXA data to optimise fat loss and muscle preservation
  • Long-term weight maintenance — metabolic adaptation management, sustainable dietary frameworks

Why we built this together

The weight loss journey doesn't end at surgery.
It begins again.

Most surgical practices tell patients to lose weight before surgery. Most nutrition practices tell patients to prepare for the operation. This site brings both together, with shared knowledge of where a patient is up to and what they need next.

My Weight Loss Journey exists because major weight loss has phases — and different clinical expertise is needed at each one. Nutrition support during weight loss helps protect muscle and prepare for surgery and recovery. Surgery, when it is appropriate, deals with what weight loss cannot: loose skin. The two are not separate. They are a sequence.

International patients

We welcome patients from across the Pacific and beyond

Dr Kumar's practice has a strong tradition of caring for patients travelling from Fiji, Papua New Guinea, the Pacific Islands, Dubai and India. The quality of specialist plastic surgery available in Sydney — at Australian private hospital standards — is high, and for many patients travelling for surgery represents both clinical excellence and significant cost advantage relative to other international destinations.
