“Too high according to you. What is a normal person?”
There isn’t much common ground when it comes to diets, mainly due to activists on the Left, but about the one thing most agree on is that too much protein is not healthy for people, and the proper amount is about 20%. Going higher stresses the kidneys and simply isn’t needed (others here can help me on this).
The real debate is what the makeup of the other macros should be - and that is either fat (in some form) or carbs.

Percentages aren’t especially meaningful and lack context. I aim for 0.8 to 1 gram of protein per pound of lean body mass in order to preserve muscle mass (based on r/ketogains recommendations). Protein is a goal, fat is a lever, and carbohydrates are a limit for me. I don’t aim for a particular amount or percentage of dietary fat because I have body fat available for fuel; I don’t need the additional calories dietary fat bring to the party. I should be consciously limiting dietary fat if I we’re serious about losing more weight (i.e. reduce body fat while preserving muscle).
