We provide the option of reversal for those with, or at risk of, type 2 diabetes.

Better sleep. Walking without pain. Playing with the kids. We know for those diagnosed with type 2 diabetes or pre-diabetes, reversal is not just about losing weight. It’s about the freedom that living without diabetes will allow you to have.

We know your journey, because we’ve lived it.

Nearly 1.7 million Australians have diabetes or prediabetes, but those suffering often feel isolated, confused and scared.

That’s certainly how our founder Dr Rob Szabo felt after being diagnosed with type 2 diabetes seven years ago. Determined to stay healthy, Rob experimented with different ways to manage his diabetes and learned about the powerful effects of a low carb lifestyle.

After just three months, he noticed something incredible. He could not only control his diabetes, but he could even completely reverse it – all without medications.

Dr Szabo founded Diversa, not only to show others how to prevent, treat and reverse their type 2 diabetes through nutritional changes, but to form a community: so that no one in Australia ever needs to feel that they are doing this alone.

When you join Diversa, you’ll receive ongoing support from your clinical team and many others who are on the same journey.

how it works

We’ve given thousands of patients a revitalised attitude towards life.

Since establishing Australia’s first Low Carb Clinic in Melbourne 5 years ago, we are proud to have helped thousands lose weight, reverse their diabetes and turn their health around.

In 2020, prior to the coronavirus lockdown, we transitioned to provide personalised, expert guidance from qualified health professionals entirely through our remote-care, subscription service.

We realised that while some patients were seeing us for their diabetes, this was only a tiny fraction of the 1.7 million Australians with type 2 diabetes who we could be helping. Our new model expands our reach and means we can provide the best personalised care and unite people with diabetes across the country.

The Journey of Diversa Health

After 4 years of serving thousands of patients in-person as The Low Carb Clinic, we have now become Diversa Health.

Diversa is a portmanteau, a fancy word that means the blending of the sounds and combining meanings of two other words, in this case “diabetes” and “reverse”. Diversa also means “diverse” in Spanish.

The core issue we’re addressing is insulin-induced conditions. In fact, perhaps the majority of Australians have some form of insulin resistance which is manifested in a variety (or diverse) types of conditions. Type 2 diabetes just happens to be the most recognisable.

Historically, the majority of patients we have helped came to us primarily for assistance with sustained weight loss, and we will continue to serve such patients.

However, with approximately 1.7 million Australians with type 2 diabetes or prediabetes, nearly all of them only “manage” their conditions with medications and carbohydrate-rich diets.

We aim to completely change the paradigm. For those Australians with or at risk of developing type 2 diabetes. Diversa provides the option of reversal.

In so doing, we seek to help Australians be healthier while reducing the healthcare costs.

Our core team

Our team of clinical experts are making that future possible. Through a combination of medical nutrition therapy and removing the barriers of one-on-one care.

Dr Nicoletta Fisicaro


General Practitioner

Treating food as medicine, Nikki is a metabolic doctor who firmly believes in prescribing diet and lifestyle changes before drugs. For a long time, Nikki felt frustrated and unfulfilled as a GP treating diabetic and obese patients with standard medical advice. Despite effort from herself and her patients she’d watch their blood sugars continue to rise over the years and felt there was nothing she could do other than prescribe more medications. When Nikki discovered that standard dietary advice was based on weak unreliable science, and that low carb, real food nutrition could not only treat but actually reverse diabetes, she has never looked back.


Pete Clarke


Co-Founder and Managing Director

With more than a decade of experience in leading teams to provide dialysis services to patients around the globe, Pete knew well that type 2 diabetes was a primary contributor to end stage renal disease. However, it came as a bit of a shock to him in recent years to learn that the epidemic was actually reversible. He became determined to help patients and key stakeholders consider a low carb lifestyle as the first line of treatment and prevention.


Dr Rob Szabo


Co-Founder and Chief Medical Officer

A GP with over 15 years experience. Having successfully reversed his own type 2 diabetes in 2014, Rob is passionate about providing the option of reversal to the many Australians suffering type 2 diabetes. He believes in empowering people to take control of their own health journey through nutritional strategies that encourage disease reversal.

As seen in


Although there is no universally agreed upon definition for the reversal of type 2 diabetes, Diversa uses HbA1c to assist in defining diabetes and pre-diabetes reversal.

Type 2 diabetes reversal is when a patient who previously had an HbA1c in the diabetic range (>6.4%) returning an HbA1c in the non-diabetic range (<6.4%) (along with the absence of medications used to manage diabetes). Pre-diabetes reversal is when a patient who previously had an HbA1c in the pre-diabetic range (5.7-6.4%) returning an HbA1c to the non pre-diabetic range (less than 5.7%).

It is important to recognise that although not everybody may be able to completely reverse type 2 diabetes, partial reversal, the reduction of medication dosages, along with the simultaneous lowering of HbA1c, will unquestionably achieve a better quality of life and improve health outcomes for those living with type 2 diabetes.
