Hi Stephen @firespooks, While we wait for other members to share their experience, I thought I would share a couple of references on the sugar and prostrate cancer.

" Should you avoid sugar with prostate cancer?
Here's another: If you are on ADT for metastatic prostate cancer, you are more likely to gain weight, and also to develop insulin resistance. One way to fight this is by limiting your sugar and simple-to-digest carbs. Bonus: keeping insulin down may also help slow down the cancer. Jun 22, 2020"

"Here’s where the myth that sugar fuels cancer was born: if cancer cells need lots of glucose, then cutting sugar out of our diet must help stop cancer growing, and could even stop it developing in the first place. Unfortunately, it’s not that simple. All our healthy cells need glucose too, and there’s no way of telling our bodies to let healthy cells have the glucose they need, but not give it to cancer cells.

There’s no evidence that following a “sugar-free” diet lowers the risk of getting cancer, or boosts the chances of surviving if you are diagnosed."
