Best way to do this is via diet

High healthy fat (high omega 3/low omega 6), moderate protein, low carb, low inflammatory diet (bordering on ketogenic diet)


Caveat about your link: the producers of that content are only interviewing the survivors who tried these options, not those who tried the same therapy and died (survivorship bias). This is coming from someone who is very open minded on using complementary therapies as adjuncts to conventional therapy

Caveat: there is little/no data on this being of benefit for prostate cancer (along with the other complementary therapies recommended). Risk/benefit ratio analysis is up to each individual...

Ketogenic diets as an adjuvant cancer therapy: History and potential mechanism

Cancer cells, relative to normal cells, demonstrate significant alterations in metabolism that are proposed to result in increased steady-state levels of mitochondrial-derived reactive oxygen species (ROS) such as O2 and H2O2. It has also been proposed that cancer cells increase glucose and hydroperoxide metabolism to compensate for increased levels of ROS. Given this theoretical construct, it is reasonable to propose that forcing cancer cells to use mitochondrial oxidative metabolism by feeding ketogenic diets that are high in fats and low in glucose and other carbohydrates, would selectively cause metabolic oxidative stress in cancer versus normal cells. Increased metabolic oxidative stress in cancer cells would in turn be predicted to selectively sensitize cancer cells to conventional radiation and chemotherapies. This review summarizes the evidence supporting the hypothesis that ketogenic diets may be safely used as an adjuvant therapy to conventional radiation and chemotherapies and discusses the proposed mechanisms by which ketogenic diets may enhance cancer cell therapeutic responses.
