Metabolic Health Mosman — Insulin Resistance, Diabetes & Weight Loss
Why am I not losing weight — despite doing everything right?
If you have tried every diet, reduced your calories, and increased your exercise — yet the weight simply won’t shift — you are not failing. Your metabolism is not working the way it should, and the reason is almost never as simple as ‘eating too much’.
At World of Health in Mosman, Dr Ranga Premaratna takes a science-based approach to metabolic health. He investigates the underlying biochemical drivers of weight loss resistance, insulin resistance, and metabolic dysfunction — and creates a personalised program to address them directly.
This isn’t a generic weight loss clinic. It’s a clinical practice grounded in nutritional biochemistry, functional medicine testing, and over 35 years of clinical experience.

Understanding Insulin Resistance: The Root of Most Metabolic Problems
Insulin resistance is one of the most common — and most commonly missed — metabolic disorders in Australia. It occurs when the body’s cells stop responding effectively to insulin, causing the pancreas to produce more and more insulin to compensate. Over time, this creates a cascade of metabolic dysfunction.
Insulin resistance symptoms in females and males may include:
- → Stubborn abdominal fat that doesn't respond to dieting
- → Constant hunger and sugar cravings
- → Fatigue — particularly after meals
- → Difficulty concentrating and brain fog
- → High blood sugar levels (even in the pre-diabetic range)
- → Polycystic ovarian syndrome (PCOS) in women
- → Skin changes such as skin tags and dark patches (acanthosis nigricans)
- → High triglycerides and low HDL cholesterol
Many people searching for ‘what are the signs of insulin resistance’ or ‘how do I know if I’m insulin resistant’ are surprised to learn that standard GP blood tests often don’t detect it until it has progressed significantly. Dr Ranga uses advanced functional testing to identify insulin resistance earlier and with greater precision.
How to Reverse Insulin Resistance Naturally
Dr Ranga’s clinically-tested approach to reversing insulin resistance combines:
- A personalised low-carbohydrate diet appropriate to your health status and preferences
- Targeted nutritional supplementation to improve insulin sensitivity (including magnesium, chromium, berberine, and specific B vitamins)
- Gut health optimisation — emerging evidence strongly links gut microbiome health to insulin resistance
- Reduction of inflammatory burden, including addressing environmental toxin exposure
- Lifestyle interventions targeting cortisol, sleep, and movement
- Regular monitoring of blood glucose levels and metabolic markers
His insulin resistance diet protocols are not generic. They are designed around your unique metabolic profile, food preferences, and health history — maximising effectiveness and long-term adherence.
Type 2 Diabetes: Management and Reversal
Type 2 Diabetes is not a life sentence. While conventional medicine often focuses on managing blood sugar levels with medication, Dr Ranga’s approach goes further — addressing the metabolic dysfunction that drives the disease.
His clinically-tested Low Carbohydrate Diet protocol, combined with targeted nutritional supplementation and lifestyle support, has helped many clients achieve:
- Significant reduction in HbA1c levels
- Reduced reliance on diabetes medication (in consultation with their GP)
- Improved energy and cognitive function
- Sustainable weight loss
- Better control of blood glucose levels day-to-day
Dr Ranga works collaboratively alongside your GP and specialist team. His role is to provide the nutritional, lifestyle, and supplementation framework that supports the best possible outcome — including the best diet for Type 2 diabetes management specific to your profile.
If you have been searching ‘what is the best treatment for reversing Type 2 diabetes?’ — we encourage you to book a consultation to discuss what is possible in your specific case.
Weight Loss That Actually Works: A Scientific Approach
Most weight loss programs fail because they treat body weight as a simple equation of calories in versus calories out. The reality is far more complex. Factors including insulin levels, cortisol, thyroid function, gut bacteria composition, sleep quality, and nutritional deficiencies all powerfully influence the body’s ability to burn fat.
Dr Ranga’s holistic weight loss approach investigates and addresses these factors. His programs are not about restriction and willpower — they are about correcting the underlying metabolic dysfunction that is preventing your body from burning fat efficiently.
His approach includes:
- → Comprehensive metabolic testing — going far beyond a standard weight loss assessment
- → Personalised low-carbohydrate or ketogenic dietary protocols
- → Nutritional support for hormonal balance and thyroid function
- → Gut health optimisation to improve metabolic signalling
- → Stress and cortisol management strategies
- → Evidence-based nutritional supplements for metabolic support
If you have been asking ‘why am I not losing weight?’ or searching for a ‘holistic weight loss clinic’ in Mosman, our clinic offers the depth of investigation and personalised support your body needs.
Metabolic Health Testing: Know What's Really Going On
- → Fasting insulin and glucose, and glucose tolerance testing
- → HbA1c and advanced glycaemic markers
- → Comprehensive thyroid panel (TSH, T3, T4, reverse T3, thyroid antibodies)
- → Advanced lipid panel (not just total cholesterol)
- → Inflammatory markers (CRP, homocysteine)
- → Nutritional deficiency testing (vitamin D, B12, magnesium, zinc, and more)
- → Hormonal panel including cortisol, DHEA, and sex hormones
This level of testing moves far beyond a standard health check, allowing Dr Ranga to identify the specific factors driving your metabolic dysfunction — and target them precisely.
