Yes, and the internet has helped quite a bit with this. Instead of a small group of people having access to research through university or hospital publishing networks, everything circulates on the internet for anyone to look at.

My prediction is that this leads to many secular trends in diet and lifestyle. People have called keto a fad, but to me it looks like what happens when basic human endocrinology and how to manipulate it becomes widely known. I don't expect people to go back to high carb/low fat diets as a weight loss intervention, ever, even once the hype has worn off.
