Of course not worrying about it works for some - and not not for others. There is such a thing as too much protein but most of us never meet that. But some do.
I wouldn’t worry until I feel something odd but I personally won’t. I never go over 4g/kg protein for lean bodyweight and my average is just somewhat above 2 and it works perfectly for me. I know it’s unnecessarily much (I am with the people who say 1-2g/kg is okay, I would go for 1.5-2 if I could stay so low regularly. there are individual differences in our protein need but this range usually works for most) but I already keep my protein intake as low as it’s comfortably possible for me - without overeating fat like crazy, that’s very easy for me so I focus on avoiding that too. Even with this, I don’t need tracking, just good food choices and my macros will be fine. I can’t track anyway as I eat fatty meat. Yesterday I actually tracked but I don’t know if my meat had 70g fat or 120… It’s always a mystery. At least I can be more sure about my protein That was over 3g/kg.
So don’t worry until your body doesn’t tell you there is a problem, I suppose - unless if you are known as someone who can sit down and eat half a sheep or something and can do that regularly? Or if you have some condition that may be not fine with much protein? Or if you have some other special reasons. If you don’t, I wouldn’t worry, a bit high protein won’t kick you out of ketosis (probably very high either but it may cause other problems), it doesn’t work like that as it was already mentioned! The human body knows its thing and only make glucose from protein when there is a need for it.
I personally don’t want to waste precious protein so I try to keep it as low it possible (I don’t need to worry about it being too low, ever) and well, it’s unnecessarily high but feels good. Most of us feel good with much protein. Ask proper carnivores who eat much meat I eat below 1 pound a day in average, pathetically low in carni circles but I love my eggs
And sometimes it’s not a good idea to keep protein just adequate anyway. I often had a day with huge amounts of fat, adequate protein and I just kept getting hungry and needed my somewhat high protein to get satiated. Protein is the most satiating macronutrients in general, of course people are very different… We need fat too, sure and it may matter which kind (to me, the fat in my protein sources are way better at satiating that the others so I avoid the others as much as I can. solid fat tissue works especially great. but many people are fine with added fat) but eating a bit more protein rich may solve some of our problems. Or the opposite, who knows? Basically eating only food items rich in protein (and fat) works best for me. I even have my circumstances and tastes, I couldn’t follow some macros I could came up with if I wanted. So I am all for not overcomplicating things. (Thinking about them is fun though. And experiments! So maybe try out different styles and find your sweet spot?)
