So, I emailed the Schwarbein people asking their opinion on whether or not ketosis is safe. They said that it is absolutely unsafe and that if I wanted to know why I would have to read Schwarzbein II.

Could someone who has read Schwarzbein II please explain the rationale behind this claim that ketosis is very unsafe? I have certainly read plenty of information pointing to ketosis being completely safe, and I've been in ketosis for much of the time over the past 10 months without any effects besides 60lbs+ of fat loss. I would really like to know, though, if there is something harmful about ketosis that I'm just not seeing.

Thank you in advance for your advice,

Tim
