I've been watching the videos and am blown away at the volume of scientific research that supports the LCHF way of eating. Yet, the medical community is not going to budge because they would have to admit they are wrong.
A statement that resounded with me is that people are born insulin resistant, they don't develop it. What develops is the degree of IR, which eventually shows up as metabolic syndrome, etc. etc. And the degree of IR is an individual thing (which we know all too well). Some people (raises hand) need to reduce carb consumption to very low level (ketosis) in order to counteract or nullify IR. Others not as much.
Another thing brought out by the speakers is the link between carbs and inflammation and that it's this inflammation that sets up the possibility of so many diseases - CVD, gastrointestinal disease and cancer, all cancers really, hypertension.... etc etc
I am more than ever convinced that when I stop eating carbs, I stop the inflammation, and I give myself a higher chance of avoiding even cancer. I have a history if IBS, which is generally thought to be caused by inflammation. On a ketogenic diet I am certain (in the absence of any test) that there is no longer any inflammation in my gut. Haven't had IBS symptoms for years (ever since going gluten-free, and especially lowering carbs).
By the way, I did have breast cancer years ago (non-invasive, en sito). Most of the time since then I've been sort of low-carb, and the last 10 years gluten-free - being VLC/HF these last 4 years. I think my WOE is a better cancer prevention than anything else I could have done. I guess time will tell.
