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.
