43. Keto for brain cancers

My friend was treated successfully at Johns Hopkins with a keto diet. No sugar, no fruit, few veggies. <20g carbs daily. Here's the study:

I'm working to de-sugar my diet for this reason and for inflammation. I would absolutely do keto if I had this dx. What's there to lose. Enjoy whole cream, butter, marscapone, good cheeses. No glucose = no food for the cancer.

Among the arguments against by those who claim it's woo woo is that it's hard for some patients to stick to. So is giving up sugar for diabetics. Some can't and do poorly. My father in law followed strict diabetes diet, enjoyed bacon, and lived to 96. Diet impacts health in many ways. And there's nothing beneficial about sugar.

Not that long ago the doctors who focused on gut health were ridiculed. Now that's become mainstream. I hope you'll share the study with your friend.

Personally, I think sticking to an extreme low carb diet would be easier than and preferable to chemo and radiation.
