You're sidestepping the broken ketone metabolism that we know about in tumors. But anyway, your point about causation, that's why I said originally that it depends on your definition of causal here. We absolutely know that low carb and fasting leads to better outcomes. I'm not saying glucose magically turns cells cancerous, but it is the fuel - the only fuel - they can use. So in a sense our massive use of sugar is causal. There's even historical accounts of introducing sugar to cancer-free populations and they all get diabetes, cancer and bad teeth.

Ok, that's a fair point. If we change my hypothesised experiment to be add high glucose concentration to cells and look for a cancerous tumor that is greater than $size after $time, I think you'd find an effect (you can read about the effects of hyperglycaemia on cancer, and given that a cancer is present, it will grow more quickly in the presence of more glucose). I guess I wanted to clarify that glucose doesn't cause cancer, but I think I understand your point now, and I think we're in agreement.

  How often is the body able to shut down small cancerous growths when they are just starting? And by giving them a feed of glucose, do they grow to fast for the body to naturally handle them? Or alternatively, without glucose, world they mostly stop spreading?
