My diet is meat heavy now. Experience generally good. Find that it's easy to maintain a consistent weight. I went keto for a while a long time ago. Very positive, after the ~1 week "flu". It helped me notice my hunger pangs were just sugar cravings. Had more consistent energy. I think keto is good for resets. Not sure anyone would need to maintain for long term unless you have other issues (aware that some mental health issues see improvements from keto).
