Look at the diet protocol for typical PET scans. It is a low sugar diet. The reason pet scans work is because tumors typically have a high consumption of sugar because they have a high metabolism. PSMA pet scans work differently so you do not have to be on a low sugar diet. Having said that, if the basis of a typical PET scan is the tumor's uptake of sugar, it would follow that reducing sugar may reduce energy availability for the tumor. I have greatly reduced my own uptake of sugar by reading labels, seeing which fruits have lower sugar content, and generally reducing portions . I am also doing this because I am on Orgovyx and I am trying to avoid the weight gain that so many people report. Worst case scenario, it will do no harm.
