Pheace: I just hope /r/keto stays up, we're on a diet here and it's the best resource of information >.<
Smannesman: It's not.
So is 'keto' a healthy and effective diet?
I vaguely remember paleo for example being criticized for being ultimately bad for your health.
It's eating almost no carbs (~<20-30), moderate protein (~80-100g, to retain your muscles), and the rest fat till you reach the amount of calories you're aiming for.
Since the body has no carbs to burn it will switch to burning fat as it's primary fuel. It's quite interesting actually. We've only just started it so we're still kind of only just past the 'keto flu' as they call it, the period where your body adjusts to the change, but I have to say I've been feeling particularly 'stable' rather then the ups and downs I used to have when eating carbs/sugar.
Maybe there's downsides but I've seen too many pro's not to at least try it :)
