I've read and watched everything Jason Fung has on his site, which is extensive, and I started off watching and reading Dr. Bernstein, who I adored, from his depth of experience, his obvious compassion, and his demeanor. I'm following the guidelines Dr Fung has laid out almost to a 'T', and have looked to those areas I'm not quite adhering to, such as cream in my coffee several times a day, instead of just once or twice, and tackled those areas as they've come up.
I'm 57 and have been obese for 30 years. You can imagine that I've been around the block as far as dietary suggestions go. I am cautious of zealotry in all its forms. Is that enough background for you to stop assuming I am one of 'those' who leapt before they looked, Brunneria? And if I had leapt before I looked, would the attitude you display with your assumptions have helped me in any way? For example, if someone asks a simple, what is PIR, is it really helpful to send them to a comment pages back, when all the comment consists of is spelling out the acronym? It took as much effort to make that poster feel inadequate as it would have to simply give her the info.
I also have a master's degree in elementary education, grades pre k - 12, and while that isn't a particularly difficult degree in terms of academic rigor, I did finish it with a 3.9 GPA (in the US, 4.0 is perfect.) Am I smart enough now for you to approach me as an equal as we talk, or do I need to throw in my IQ score too? 140, what's yours? Don't worry, I won't be intimidated if it's higher, my sister's is 160, my father's was 145, my other sister's was 125, my mother was never tested.
I know I am being snarky here, Brunneria, and I shouldn't be... is it ever helpful? But I was stung by the attitude in parts of your response to me. The judgments and attitudes towards yourself and the learner in the teacher/ student relationship are crucial in most learning situations. It is very tempting for many to fall into an attitude of, I have superior knowledge to yours, I will impart my superior knowledge into your empty (or faulty) vessel, and it works about as well as the SAD diet.
If you had presented yourself as my student, had trusted me with that vulnerability, I would, 1) not be snarky, and 2) suggest you approach your teaching of others with the phrase in your mind, 'when one teaches, two learn.' That btw, has been scientifically proven.
I know I am being 'overly sensitive' and reactive here, but that's what happens when you insinuate someone is being stupid with one hand, while offering your experience and wisdom with the other. Especially when the student is as vulnerable as I, and I am guessing many more, are as we are trying to restore our battered health.
