The Ketogenic Diet and Cancer

The Ketogenic Diet and Cancer

The ketogenic diet (KD) has been known by many for its effect on weight loss, but it also offers a variety of health benefits against conditions like diabetes, cancer, epilepsy and Alzheimer’s disease, etc.

The question to ask is, can KD fight cancer?

There is a growing amount of positive clinical evidence that it can.

While large scale, controlled studies are still lacking. Many early studies show an overall positive effect on many solid tumors like Brain, Prostate, Colon, Pancreatic, Lung, and Breast.

However, two tumor types warrant some caution based on preliminary data are melanoma and kidney cancer.

How does KD work?

KD takes advantage that the majority of cancer cells only use glucose as fuel. By consuming a low-carb/high-fat/moderate-protein diet, you will effectively switch your body’s fuel source from glucose to ketones. This puts constant pressure on the cancer cells’ metabolism and this will make them more susceptible to pulsed cancer therapies such as chemo, radiation, or even IV Vitamin C.

Sounds simple? Yes and No. There’s a lot of education and lifestyle changes that are required to successfully implement a full and effective KD, especially for a cancer patient. The right approach is essential, once all the initial hard work is done, it becomes easier and most patients feel better. So it’s best if you can work with an integrative or functional practitioner to get started in the right direction.
