Q: Does Keto create stress on the immune system, and allow cancer to grow?
The ketogenic diet does not create stress on the immune system. According to Virta Health, and many other sources, the ketogenic diet is great for reducing inflammation. If you’ve ever looked at side effects for chemotherapy and endocrine therapy for cancer, you’ll see that lowered white cell counts are very common. In fact, its so common that doctors do chemotherapy in cycles, just to give the body a chance to heal and let white cells increase again. The medicine I was just on (Talzenna) is so notorious for lowering white cell counts that there is a protocol for dose reductions. I’ve been fortunate to be taking Transfer Factor Plus as an adjunct to my therapy. The Transfer Factor has been supporting my immune system, along with the ketogenic diet. In fact, my white cells have only just recently dipped below normal, even though I’ve been on Talzenna for a few months. I’m also fairly healthy otherwise, in that I’m not getting sick with colds or fevers that could complicate treatment. There is also a lot of anecdotal evidence about how people have felt much better on keto. They have lowered inflammation levels and are in better health overall.
Question: Where do cancer cells get their food sources?
Many cancer cells feed off glucose. This is well-known. Point-in-fact, when you get a PET scan to stage and get information about breast cancer, what do they do? They give you an injection of a radioactive sugar isotope. Then they make you wait an hour while all the tumor cells take up the glucose so they can see how it lights up on the PET scan.
Is sugar the only source, no. But it is the most common.
