It's funny that protein everything is taking off just as more data seems to come out that you really don't need as much protein as previously thought, even for vigorous weightlifting (~0.82g/lb of lean body mass seems to be a sufficient number), which isn't really all that hard to get from regular old high protein food. There's no good reason to infuse it in everything. I've been lifting for many years now, and have not noticed a difference from when I used to follow the old 1g/lb of body weight rule.

Most folks (at least in North America) get no where near the recommended level. It's silly to have protein infused junk food, but a shake or protein powder make it a lot easier to get to the right level than remembering to have 3 hard boiled eggs.

And somehow all the people I've met mentioning figures from papers (be it 1g, 1.4g or whatever) always seem to skip the "lean" part of "lean body mass" part, which is again a decent difference.

Isn't age also a factor?

What's "regular old high protein food"? Do you mean something like meat every meal? When I recorded my meals I found my protein intake to be quite low (I don't eat meat. I eat fish but not every day.).

All the people on GLP-1 drugs are told to make sure they get enough protein. My dad, who is on one of them, was saying his friend (also on one) was saying he felt it was like a cheat code for being able to eat pasta... so I think a lot of people are eating the same old stuff, but just feeling less guilty about it.

They still want to eat Doritos, and now they can buy the protein Doritos and act like they are following the doctor's orders, even though that's not in the spirit of what the doctor was saying. There are also a lot of products that change little to nothing, but still slap a "Protein" label on the front of the box.

We saw similar things with "low carb" versions of everything during the Atkin's craze. Before that we saw everything made into "low fat" in the 80s, which we're still suffering from. It's likely a big reason why we as a society have a need for weight loss drugs in the first place.

0.82g/lb is a lot of protein. That's basically what what bro science was saying for years (2g per kg) and it's not easy to hit if you count quality protein that's bioavailable so I don't know what the point is here.

For averge Joe to hit 0.82g/lb he would need to eat 600g of lean beef every day. Or 33 eggs.

... also Menno Henselmans while he does a lot of great work that outweights everything he posts tons pseudo-scientific where's often clear he just did a basic Google Scholar search. Plus he seems too eaeger to "debunk" but often barely even understands deficiencies of many of the studies he references. A lot of people take his website for some holy grail of "scientific bodybuilding" because he's trying too hard to market it that way and he's been wrong many times and built arguments on foundations he barely understands.

Examine.com for example has different figures and it's a website where studies are reviewed by actual PHDs and graded by their strength not just simple Google Scholar search.

Your priors on what normal amount of protein amounts to is way off of the general public, at least as of 5 years ago.

Wasn't that always bro science ? From what I remember when I looked into it most people couldn't digest more than approximately 1.7g of protein for every kg of body weight. At the very upper end. And that's just digestion - not even actual use - and it had to be spread out across the day.

>regular old high protein food

You don't need to eat "high protein food" to get adequate protein.

Let's say an 80 kg moderately active man needs to eat 2600 kcal/day to maintain body weight. According to current guidelines, that man needs about 0.8g/kg of protein per day, or 64 grams per day.

White bread has about 2.6 grams of protein per 77 kcal.

https://tools.myfooddata.com/nutrition-facts/174924/wt1

You have: 2600 kcal / (77 kcal / 2.6 grams)

You want: grams

* 87.792208

/ 0.011390533

That works out to about 88 grams of protein per day eating nothing except white bread.

It's difficult to not get enough protein unless you're eating too few calories overall.
