Paleolithic ketogenic diet (PKD) as a stand-alone therapy in cancer: Case studies

Zsófia Clemens, Andrea Dabóczi, Csaba Tóth


INTRODUCTION: Outlook for cancer patients remains poor despite ”best available treatment” which includes surgery, chemotherapy and radiotherapy in most solid cancers. Genetic profiling attempts to use matched chemotherapy and the use of high-cost biological therapies, so far, did result in no major breakthrough (1). Metabolic therapies have been suggested as a promising alternative option. Yet, clinical group studies that have been published, provide next to no evidence for a benefit in hard clinical endpoints of cancer. Previously, we put forward (2) that the apparent ineffectivity of the ketogenic diet in cancer is likely due to two factors. First, all published studies included cancer patients that also used chemo- and/or radiation therapy. Second, all group studies used the classical version of the ketogenic diet which is based on vegetable oils and dairy, an evolutionary maladapted, erroneous version of the ketogenic diet.

METHOD: Since 2011 we have been using the paleolithic ketogenic diet (PKD) in the treatment of chronic diseases including cancer. The PKD is an animal meat-fat-based diet similar to that originally proposed by Voegtlin in 1975 (3). In our database, there are 70 cancer patients who meet the criteria of following the PKD for at least two months. Out of these patients, we present two cases where the disease first recurred after the standard oncological treatment. Later on, both patients stopped standard oncotherapy, and decided to use PKD as a stand-alone therapy. The two patients were in a close follow-up and experienced stable disease and regression, respectively. In addition, out of our database, we have selected the best-performing patients (having a follow-up of and being progression-free for 2< years, and being alive at the time of the current analysis). It was our aim to find out what they have in common.




Cancer type: Recurrent glioblastoma (grade 4 brain cancer)
Age: 53 years old (at diagnosis)
Medical history: bladder cancer, high blood pressure
Therapy 1 (Jan – May 2016: 4 months):
Surgery+chemotherapy+radiotherapy → Aug 2016 recurrence
Therapy 2 (Sep 2016 – currently: 30 months):
PKD alone → progression-free, symptom-free, medicine-free


Follow-up MRI scans



Intestinal permeability measurement (PEG400): normal at 17 months on the PKD.



Kaplan-Meier curve for glioblastoma survival for 10,743 patients from the National Cancer Registration Service (UK) vs. Pat#1 survival




Cancer type: recurrent cancer (metastasis of breast cancer in new locations: in the liver and in the hip bone)
Age: 46 years old (at recurrence)
Medical history: invasive ductal carcinoma of the breast (2013)
Therapy 1: surgery, chemotherapy, radiotherapy, hormone therapy (2013 – 2018) → metastasis (liver, hip bone)
Therapy 2: PKD alone (Oct 2018 – currently: 5 months) → regression in the size and metabolic activity of the metastases

PATIENTS #3,4,5,6,7

* Stable for 25 months, then slight progression with decreasing adherence (see graphs for blood glucose, urinary ketones, ESR and CRP)





CONCLUSIONS: Pat#1 with recurrent glioblastoma showed stable tumor size for the last 30 months. Pat#2 with recurrent metastasis showed a significant decrease in the size and the metabolic activity of the metastasis in five months. Both patients used the PKD as a stand-alone therapy. Retrospective analysis showed that our best performing cancer patients strictly adhered to the diet and received no chemotherapy or radiotherapy. These patients were also not taking supplements or medicines. By contrast, out of the 70 patients in our database, no patient receiving chemotherapy or radiotherapy was progression-free at two years (even with strict PKD adherence). Chemo- and/or radiation therapy possibly decreasing efficacy of metabolic therapies was previously also suggested by Seyfried et al (4).

We are managing patients with chronic internal diseases using a dietary intervention method. These diseases include all types of diabetes, autoimmune diseases, such as Crohn’s disease and rheumatoid arthritis. But it also includes atherosclerosis.

We are working with specialists who are highly experienced in epilepsy and cancer as well. We provide complex rehabilitation from diagnostics to complete recovery.

In case you wish to consult us, we will ask for your medical documentation in advance. You may send it electronically or by surface mail. Only having read your documentation we are able to fix an appointment with you.

Dear Patient,
