Been doing this a few months. There’s a couple of issues:
I haven’t really lost any weight. Or at least it’s stalled.
I don’t have any of the positive symptoms associated with ketosis: i don’t taste metal in my mouth, I’m not brimming with energy as some people claim, I haven’t noticted any super levels of focus. I also get hungry about every 3 hours. I certainly couldn’t skip meals, nor do I want to.
