What exactly is the problem doing keto natural? I've been on it for almost 4 weeks now and have been seeing results past the initial 1 week dry up. I lost some size\strength but figured that was normal and would return quickly once the diet is discontinued.

What I'd like to know is does anyone else get the shitty headaches? They've mostly subsided but I still get that sensation like a headband is pulled too tightly. Not really painful but noticeable nonetheless.
