Let me sum up KETO rule #1:
If you’re not 100% serious about doing it scientifically correct - that must include your personal medical/physical data - and just “sorta” follow some of the trends you like on the internet (or a cool gym buddy told ya...) - you will do damage to your system and NOT gain any long-term benefit from your experience. Keto done wrong is actually super dangerous!
You cannot just "go Keto" and not exercise... You're eating healthy, that's good, but you will NOT achieve a beneficial ketonic state; never!
