The irony is everyone already seems obsessed with protein these days, which I guess plays nicely with meat lovers / producers. The last thing Americans need is more encouragement on the protein front IMO. Suddenly everyone thinks they're a body builder when it comes to food.
The few friends I've known were attempting ketogenic diets over the years kept focusing on the protein side when the actual diet is supposed to be dominated by fat. They've all experienced kidney problems of one sort or another, surprise surprise!
I mean protein does fill you up faster and better with fewer calories which is good for weight loss or management.
> protein does fill you up faster
You are being pretty fast and loose with your language here so I will alight what I think you are trying to say.
"Fill you up" I must assume means that you are implying the state of feeling "full" or satiated.
There is really only one study in the field of broad food source satiety: https://pubmed.ncbi.nlm.nih.gov/7498104/
Potatoes are the most satiating food at 323% that of white bread.
The second is Ling fish which is a source of protein, but another one of my assumptions is that when you say 'protein' I am doubtful you mean 'ling fish'. So assuming you mean a 2026 American definition of 'protein' you're probably referring to cow flesh (beef) which is only 176% of white bread, almost half of potatoes.
So, in the future I would suggest spreading the word and correcting your comment by saying "I mean potatoes do fill you up faster"
> I mean protein does fill you up faster and better with fewer calories which is good for weight loss or management.
Thank you for exemplifying the problem so clearly - conflating protein with fat when we're really talking about a simple carbohydrates issue of high energy density with negative satiety.
Excess protein is excreted renally, it's easy to overdo and can cause serious problems.

Protein is actually pretty hard to overdo naturally. If you've ever tried to follow the high protein guidelines and you're a taller or broader shouldered person you'll find that getting that amount of protein requires supplementation or a lot of focus on lean meats. I'm not saying everyone needs to go "high" protein, I'm just saying that worrying about the amount of protein you're eating is probably not worth doing. You'll feel pretty full if you eat a lot of protein.
Keto is not just "high fat" though. Keto is about producing ketones, and going too high fat can actually be counterproductive there, at least for weight loss. (You want to be liberating fat from your storage, not getting it from external sources)

Not than fat. Fat fills you up fastest, per calorie.
Hmm, how do you figure? Just about every source I can find shows slow burning carbs, fiber, and protein rich foods blow fatty foods out of water in terms of satiety. (if you are using a metric other than satiety to represent "fills you up", feel free to correct me)
