I'm not opposed, as protein seems to be a good target to prioritize, but claiming there's a war on protein just seems so out of touch to the point of absurdity. It's practically the only thing that people care about right now.
Most of which are loaded with crazy amounts of sugar to make them taste good.
Have you ever looked at the label on a cup of non-plain "Greek" yogurt? (Which is 90% of the yogurt aisle.)
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!
The normal recommended daily intake for protein is 0.8 g/kg. 1.2-1.6 is silly; that's a recommendation for athletes.¹
Starches have been a dietary staple in pretty much every society forever. Sugars have not. It's silly that they treat grains as a "sometimes" food.
There's also the weird boogeyman of "processed food." Almost all food is processed to some degree & always has been. We've been cooking, baking, juicing, fermenting, chopping, grinding, mashing, etc. long enough that it influenced the shape of our teeth. Certainly we haven't been making Pizza Pockets that long, but the issue there isn't processing, it's ingredients. And the reason people buy Pizza Pockets isn't that they think they're healthy—it's that Pizza Pockets only need to be microwaved, and cooking a real meal takes time that a lot of people just don't have.

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.
It's very hard to overeat protein naturally. It's very easy to overeat starches and other carbohydrates naturally.
With regard to "processed" food, it's not a great label. I would use this metric: could you conceivably produce this in an average kitchen with the raw materials? If you can, it's probably safe, if you can't, it's probably something you shouldn't eat. For instance, processing often means "partially hydrogenating" a fat, or milling grains into a fine dust and bleaching them. Sometimes chemically produced oils are deodorized, because they would otherwise smell very unpalatable. You generally should not want your food to be bleached or deodorized..
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)
ex: Whey protein isolate is less complete than actual milk... though milk has sugars and enzymes that you may not want to consume.
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"
Scientists do not write books when they have actual, meaningful findings.
You've made this claim all over this comment section, so it's pretty frustrating to find it comes from a pretty awful source.
I promise you, it is trivial to overeat protein. Americans love their 16oz steaks, and yet one pound of steak in a single meal is almost certainly "Too much" for a non-athelete diet.
Meanwhile, simply look to every eating competition which uses a meat. There does not seem to be any natural limitation to overconsuming meat.
However, this definition of chemical modification doesn't really include hydrogenated vegetable oil. Industrial hydrogenation is done by raising oil to very high temperatures in the presence of a nickel catalyst & then adding hydrogen. We modify it on a chemical level, but primarily by heating it, not by adding reactive substances. And if that counts as chemical modification, then so does cooking!
Anyway, no—people generally used "processed" to describe a particular vibe they get from certain foodstuffs whose production seems too industrialized. There's no rigorous basis for determining what is and isn't "processed" because people use it to describe their feelings about food, not any underlying property of food.
If you search a simple question like "is bread processed," you get a bunch of articles saying "well, since there's no agreed-upon definition for processing and the definitions we do have aren't particularly clear, there's really no answer to the question. But don't worry, because (given the overwhelming vagueness of the category), it's also impossible to say whether processed foods as a category have any health implications, so you shouldn't worry about it."
It's genius really.
To reiterate, starches have been a dietary staple in pretty much every society forever, whereas meat has been relatively expensive and rare. The obesity epidemic, which began in the 1970s, did not correspond with the invention of flour or rice.
> I would use this metric: could you conceivably produce this in an average kitchen with the raw materials?
This is completely arbitrary. Why is "milling grains into a fine dust" proscribed, when blending soup in an average kitchen's food processor is fine? We've had mills for millennia and food processors less than a century. Plenty of raw foods smell unpalatable; that doesn't mean the cooked version is secretly smelly or whatever. Besides, what is and isn't a "raw ingredient" is itself arbitrary. I can't make any type of vegetable oil at home, deodorized or otherwise—I don't have an oil press. I can make lard, but that doesn't mean it's better for me.
You're talking about the vibes given by various foods here, rather than their actual health effects.
