“Before a PET scan, my spouse is given a sugary drink. Then the scan is done which lights up all the cancer locations.”
I have been wondering how well a Keto diet would do.
Check out Dr. Berg, and others, on YouTube.
They all would say that,
1) Sugar is what feeds cancer
2) Keto is a very low-sugar diet
3) Therefore, a keto diet would benefit a patient diagnosed with cancer (or diabetes, or heart disease, etc.)
