Admittedly the nutrition space is very polarized, filled with almost fanatical zeal. It can be difficult to have rational and productive discussion without triggering passions and talking past each other. That's why I'm so excited every time good high quality science gets published.
Personally I don't care what nutritional plan people follow, but if they have problems I want them to know there is a viable option for them.
It would be great if doctors screen for insulin resistance annually, to catch people early before it becomes a big problem.
