With all due respect, Dr. Fung exaggerates the science. He has reasonable hypotheses, then exaggerates the degree of current support for those hypotheses. He cannot be fully trusted, but his ideas should be dismissed, or at least questioned, unless we have better evidence than we have now. Some people call him a "quack" and I won't go that far, but many of this theories and ideas are simply not scientifically sound nor peer-review tested. https://biolayne.com/articles/research/its-not-calories-its-hormones-a-response-to-dr-jason-fung/ Of course you're entitled to follow anyone or anything at your choosing. I just don't want to sidetrack this thread from OP's intended questions, but if Dr. Fung's mantra works for you then go for it but do so doing it with full and complete knowledge.
