There was a study decades ago with similar findings. Nothing new. I’ve always wondered if the fasting (due to nausea) that occurs under Chemo is what really affacts cancer.
I have stage IV Colon Cancer. Suppose to be dead 18 months ago but I my wife and 5 kids didn’t like that plan for a 41yr old. You make a good point about fasting and chemo therapy. Initial research on several chemo drugs found that they work but they worked at the same results as just fasting. It can be argued that a great deal of chemos effectiveness comes simply from beating the a patient till they hardly eat or drink. The newer drugs and immunotherapies show better results.
On a side note voluntary fasting has great effect on restricting tumor growth and shrinking them, It is also a great way to avoid many kemo side effects, As your body begins to starve (still drink plenty of water and salt) your cellular metabolism turns to ketogenis. Your healthy cells enter a protective state which helps them from being damaged by the chemo drugs or radiation. They maintain their energy through ketogenis (burning fat and proteins) while he cancerous cells rely heavily on glucose which is mostly absent when you are ketogenic.
