So what is 'allowed'? Because I have been seeing 'low calories' (fruits/carrot juice etc) to nothing, even no water to make sure your digestive system does not trigger at all. I know no-one knows this for sure, but what is the current theory?

If you're fasting for this sort of thing, you do not want an elevated insulin level. High insulin levels disable autophagy pathways.

The best way of doing this, based on years of science, would be, well, to eat nothing for 24+ hours at a time, but make sure you stay hydrated; as in, actually fast. The second best would be to seriously curb your carbs, under 30g a day; also tied for second best is to eat just once a day, none of this unscientific three square meals hogwash.

Three of these together could halt the progress of some cancers, and before the shitstorm that was 2020, scientists were publishing papers involving animal models on this.

Steve Jobs did none of these, and was, sadly, off in la-la land when someone with his money and connections could have had access to next generation scientifically-based treatments. Fruitarianism is, frankly, dangerous.

The idea would be to have zero caloric inputs.

So water and coffee or tea (without milk, of course) would be fine. You're trying to avoid an insulin response and firing up the entire machinery of digestion.

I think it's non-controversial to say that this starves the cancer cells.

Perhaps less certainly we can also say that digestion demands a lot of resources and is an interrupt for a lot of other processes. When your body has nothing to do for 24-36 hours eventually lower priority tasks get attended to ... like garbage collection.

Student said that sadly cancerous cells could last longer starving than healthy cells.

Not zero. Fat has zero effect on insulin. You need to limit carbs and proteins.
