He wasn't fasting, he was on fruits diet.

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.

Yeah, and he also had a highly treatable form of cancer and access to the best medical care in the world. Unfortunately his arrogance got the best of him.

He was also on the fruits diet before the pancreatic cancer. Makes you wonder if the fruit diet contributed to the cancer.

He drank carrot juice which I'd say is severely limiting your caloric intake.

Also keep in mind that sugar is the enemy. Your body has chemistry to make sugar - there is no-need to ingest it.

Jobs also had pancreatic cancer. It's just about the worst cancer you can get. Over 95% mortality rate. I don't think he did himself any favors by eschewing medical treatment in favor of alternative "medicine", but the harsh reality is that he was doomed no matter what.

> Jobs also had pancreatic cancer. It's just about the worst cancer you can get. Over 95% mortality rate.

Jobs had GEP-NET cancer, which have 5 years OSR of 70% at stage IV. It's a slow growing cancer, very survivable and even surgically curable in early stage.

The fast, almost always fatal is the pancreatic adenocarcinoma.

Also, the mortality rate of a cancer is a function of many variables (stage at the time of diagnosis, tumor differentiation, tumor location, etc.). A number like 95% doesn't make any sense without a lot of context.
