I'm glad your dad got better, it had nothing to do with his diet and fasting. It's no different than Steve Jobs stubbornly becoming a fruititarian to treat his cancer. If his immune system had fought it off, then fruit would be a cancer cure and all his doctors would be idiots.

Youtube/Internet experts are one of the largest propagators of medical misinformation and are actively harming people every day, and if I've ever been in favor of restricting free speech, it's giving out medical advice without a license. If we can restrict giving legal advice, and everyone understands how painfully stupid you'd have to be to represent yourself in court without a law degree, then we can restrict giving medical advice, and hopefully people can realize how painfully stupid you'd have to be to manage your own medical treatments without a medical degree.

Regarding Steve Jobs, that's unfortunate for him because even my grandmother in Poland used to say "sugar causes/feeds cancer" when she tried to get us to stop sweetening our tea back in the 80s before we left.

Somehow she knew what several doctors and researchers are now documenting, that cancer cells have a much harder time growing without ample amounts of glucose.

Oh great, another expert. Except without the 30 years of research and experience.

One guy wins the nobel prize for detailing a function of fasting and its effects on the immune system and cell repair/death... But fasting doesn't help! We know this, because a guy on hacker news said so.
