It’s mainstream, but The Sun so not exactly high brow 
Whenever I’ve seen keto in mainstream news in the UK it has been negative or a passing mention, but here’s an article that’s actually positive.
It mentions some studies that show some carbs are essential, so I am interested to read what those are about and if they have any merit. I think the only need for carbs is to fatten up for when food is scarce, which is thankfully never for us ketoers.

Hooray for the media getting the word out on keto!!
