Fung has lots of articles on Medium and /r/fasting is a great resource. Fung and also Taubes books are great and point out he maddening simplicity, that diabetes is high insulin is high sugar intake and that we treat it with... higher insulin. It's insanity, and because we can't see the wood for the trees we have smart people go study things like how much titanium you have in your body rather than solving the actual problem of carb intake.
