Important Information

For the duration of the the COVID-19 pandemic we are offering Telehealth consultations with Dr Johnson at no cost to you. You will be offered the opportunity to have an assessment made of your metabolic health, relevant investigations ordered and then a follow up discussion of these results and recommendations.

Our normal range of medical services will be restricted to the above, however we can offer supervision for ketogenic diets where appropriate . This service has an hourly rate, not covered by Medicare.

Please either: call 3357 3470 or send an email inquiry via our contact page.

Our current office hours are Monday to Thursday 9.00 am to 4.00 pm.

The glucose ketone index (GKI) calculator:

GKI = glucose reading divided by ketones  reading, in Australia these values are given in mmo/L. For therapeutic value this number should be less than 1.

A device is widely available in Australia that gives both of these reading albeit with separate strips it is the Abbott Opita Freestyle.

Background: Metabolic therapy using ketogenic diets (KD) is emerging as an alternative or complementary approach
to the current standard of care for brain cancer management. This therapeutic strategy targets the aerobic fermentation
of glucose (Warburg effect), which is the common metabolic malady of most cancers including brain tumors. Th
KD targets tumor energy metabolism by lowering blood glucose and elevating blood ketones (β-hydroxybutyrate).
Brain tumor cells, unlike normal brain cells, cannot use ketone bodies effectively for energy when glucose becomes
limiting. Although plasma levels of glucose and ketone bodies have been used separately to predict the therapeutic
success of metabolic therapy, daily glucose levels can fluctuate widely in brain cancer patients. This can create difficult
in linking changes in blood glucose and ketones to efficacy of metabolic therapy.
Methods: A program was developed (Glucose Ketone Index Calculator, GKIC) that tracks the ratio of blood glucose to
ketones as a single value. We have termed this ratio the Glucose Ketone Index (GKI).
Results: The GKIC was used to compute the GKI for data published on blood glucose and ketone levels in humans
and mice with brain tumors. The results showed a clear relationship between the GKI and therapeutic efficacy using
ketogenic diets and calorie restriction.
Conclusions: The GKIC is a simple tool that can help monitor the efficacy of metabolic therapy in preclinical animal
models and in clinical trials for malignant brain cancer and possibly other cancers that express aerobic fermentation.
