Speaker Bio

Martha is a Registered Dietitian in Ontario, Canada, with over 30 years experience working in many areas of nutrition.  She currently works in Long Term Care (nursing homes, gerontology) and has a private practice, Primal RD, promoting a LCHF diet and lifestyle for healthy aging and chronic disease prevention. 

In August 2018, she discovered the presence of a large ovarian cyst and after its laparoscopic removal in October, she was informed that it was Stage 1C ovarian cancer, unfortunately ruptured in the removal process.  Chemotherapy was recommended, leading Martha to do a deep dive into the research around the metabolic nature of cancer and how nutritional modifications can have a powerful impact on these metabolic abnormalities.  This led her to develop and use a protocol of ketogenic diet and targeted therapeutic fasting to significantly impact on her response to the recommended chemotherapy.  This combination of conventional cancer treatment and supportive metabolic interventions has proven to be powerful and has started a new passion in Martha to share this information with others who are travelling the journey of cancer treatment.

Protecting Your NEST – Dr Tony Hampton





As a Registered Dietitian, I am a registered health professional and my practice is regulated by the guidelines of my professional organization. I am not a medical doctor and cannot communicate a diagnosis or adjust medications.  It is recommended that clients who are under medical care for specific conditions communicate with their MD’s regarding their intention to follow a Low Carb High Fat diet, a Ketogenic Diet, or Therapeutic Fasting, as adjustments to medications may be required. Each person is responsible for their own lifestyle choices and the consequences of those choices. The goal of  Powerful Beyond Measure and Primal RD is to give clients the tools and support to make choices that empower the best health outcomes.
