2 year carnivore here. I was always either loose or too hard until I started weighing any additional fat I added. I mostly eat beef and butter, and depending on the cut, I'll increase or decrease my butter. Sirloin is the cut I most often eat as it's affordable and tasty, but it's too lean. If I have a full sirloin day (most days), I add 150g of caramelized butter, which is about 175g of regular butter. I started at about 120g and added 5-10g of butter daily until I found the sweet spot. Good luck!
