Cancer and Low Carbohydrate Ketogenic Diets

Posted on July 01, 2015 by Ruth Buttigieg | 0 comments

Over the past few years more and more interest has been growing into the use of dietary therapies - ketogenic diets to be precise. Interest is growing into their potential use as an adjuvant therapy alongside more traditional cancer treatments such as chemotherapy and radiation therapy. Earlier this month, an interesting paper was published which looked further into the use of ketogenic diets as a viable treatment option for cancer. In this blog we hope to shed some more light on how lifestyle changes, especially dietary, can have a role in cancer treatment.


The World Health Organisation (WHO) estimates that around one third of cancer deaths are due to the 5 leading behavioural and dietary risks: high body mass index, low fruit and vegetable intake, lack of physical activity, tobacco use, alcohol use. Therefore, our dietary choices have a greater impact than simply providing fuel for our body.


How do our food choices contribute to ill health?


The simple answer to this question is that we are not eating enough nutrient rich foods to help meet our body’s daily vitamin and mineral needs. It is also not just a question of eating too much, but also about eating items that our body is simply not designed to eat. This is when the “quality” factor comes in, in that we need to be mindful of opting for food choices that are naturally more nutrient dense.


Research continues to show that energy rich and nutrient poor foods do have a role to play in disease and that we need to decrease the frequency at which we eat these items to improve health.


So, how does a low carbohydrate ketogenic diet help with cancer management?


Cancer cells are sugar addicts.


This particular feature of cancerous cells was first discovered in 1924 by Dr. Otto Warburg and he proposed that cancer is a metabolic disease i.e. a disease brought about by the cells changing the way they fuel themselves. In this case, he noticed that cancer cells much preferred using sugar as fuel and were unable to use any other sources to provide themselves with energy.


Therefore, the theory he put forward was that by changing the way the healthy cells fuelled themselves (the unaffected healthy cells are able to switch to other energy sources without they themselves being compromised), one would be able to “starve” cancer cells as they lacked the facility of fuelling themselves through other sources.


It is in fact, this metabolic inflexibility of cancer cells that makes the ketogenic diet effective against cancer cells.


What does the science show?



Due to the nature and implications of this theory, the number of studies looking at the effects of a ketogenic diet on human cancer patients are few and far in between. Hence the data that we have on the physiological effects of a ketogenic diet are mostly based on animal studies.


Counter arguments to the validity of this approach will be that mouse studies are not indicative of any success in humans. However, mouse studies, especially in cancer, have provided insight into the biology of human cancers as well as other disorders and are a cornerstone in the development of potential therapies.


This study published in June 2015, looked at a combination of therapies targeting the cancer cell's ability to use sugar as a fuel. They investigated their theories in mouse models as well as in lab tissue samples.


What they found was that through a combination of ketogenic diet, ketone supplementation and hyperbaric oxygen therapy, all target overlapping biochemical pathways prominent in cancer cells. What they found is that this combination therapy is safe, non-toxic and could have a place as an adjuvant therapy to current standards of care.

There is a growing list of research that has been addressing this issue and the major papers are listed below in the reference list.


How Can the Natural Low Carb Store help?


Here at the Natural Low Carb Store we believe that a low carbohydrate ketogenic diet can play a role in cancer management. It’s about meeting our body’s vitamin and mineral requirements and promoting a healthy self.


All our products have been designed to allow our body to go into a state of dietary ketosis. In fact, our products are also used as part of various ketogenic dietary therapies aimed at managing epilepsy as well as diabetes.  


Feel free to get in touch with us, we’ll answer any questions you have and help you make an informed decision.
