Our Preoccupation With Protein Intake (substack.com) 108
A review of published meta-analyses examining protein supplementation found no evidence supporting intake beyond 1.6 grams per kilogram of body weight daily, according to an analysis by cardiologist Eric Topol. The review examined multiple randomized controlled trials encompassing thousands of participants. The most widely cited Morton study, which included 1,863 participants across 49 trials, showed no statistically significant benefit at higher protein levels, with a p-value of 0.079.
Recent research from Washington University identified the essential amino acid leucine as activating mTOR in macrophages, promoting atherosclerosis progression. The mechanism was demonstrated in both mouse models and human studies measuring circulating monocyte changes following acute high-protein challenges increasing dietary protein from 22% to 50% of energy intake. Current USDA data indicates 55% of American men and 35% of women already exceed the 0.8 g/kg/day recommendation from the National Academy of Medicine. The protein supplement industry, exemplified by David bars containing 28 grams of protein in 150 calories using a modified plant fat called EPG, projects $180 million in 2025 sales.

There's also this weird notion among a large percentage of the population that a high-protein diet is "natural" and is what our ancestors ate. Certainly *some* hunter-gatherers ate a lot of protein (there's a great deal of diversity in traditional diets), but the mean hunter-gatherer society did not. In areas rich in sago, for example, it's common for ~75% of calories to be from sago alone (nearly pure carbs), and in extreme cases up to 90% - not counting other plants on top of that - with much of the protein coming from sago grubs.
If there's one thing that our ancestors almost universally tended to eat a lot more of than today (unless your ancestors were, say, Inuit), it's fibre.
Also, meat is not a synonym for protein. A typical green veggie without its water, like freeze-dried broccoli (~0% water content) has ~50% more protein per calorie than your most common grade of ground beef (20% fat) at 0% water content (beef wins per-gram, but only by ~20%), and watercress at 0% water is nearly as high as cod at 0% water per-calorie. The main difference is that said veggies are overwhelmingly water before cooking, and that most modern peoples eat way less of them than they do of meat, so in a typical modern diet it's a small percentage. But hunter-gatherer societies tend not to be so picky, and plant-based food sources in most places tended to be more available than meat-based ones - in the stone age, your ancestors were probably chowing down heavily on things like nettle stew, wild cabbage, goosefoot, dock, mugwort, plaintain, etc. That said, starchy or fatty plant-based sources tend to have poor protein/calorie ratios, and meat provided an important supplement (as well as hard-to-get nutrients like B12 and iron).

When I work out hard (resistance training to beyond failure) I find that consuming protein at around 1.6-1.8g per kilo of body weight significantly improves my recovery time -- perhaps because of the effect on muscle-protein synthesis which seems to be optimal at this level.
Working out hard with lower levels of protein intake adds at least a day to my recovery so it's easy to see why, given the fixation on strength and fitness that abounds right now, many people are consuming more protein than they might actually need if their goal is simply to remain healthy.
One consideration for many is that when you bias towards a high-protein low fat/carb diet it becomes easier to lose weight or prevent weight gain. Protein is generally more satiating than carbs and leaves you feeling fuller for longer, reducing hunger pangs. A diet higher in protein is also less likely to produce insulin resistance (type 2 diabetes) than one higher in carbs. However, protein is usually also far more expensive (per calorie) than protein which can be a factor in many people's decision-making.
Increasing protein intake (as a percentage of total calories) is also important as you age because it plays a role in reducing the effects of sarcopenia, a condition that affects most over-50s and predisposes people to becoming frail and increasing their likelihood of death from many causes.

Carbs, Fats, Fiber and Proteins. That is about all we eat.
Carbs and fats are the things we love to overeat. Nobody really likes fiber.
That leaves protein. We can eat more protein without ballooning up. So people make all protein diets. It's something we an eat and lose weight.
Do you want protein with that? (Score:2)
What really bugs me is that when I go to a restaurant and order some vegan type entree, the waitperson will often ask if I want to add some "protein with that" by offering to put a slab of meat on top of it.
This is profound ignorance of the protein content of plant food (or maybe just commercial up selling greed).

No it's not, it's catering to public interest. In fact, I suspect the "profound ignorance" here is yours, "plant food" and "slab of meat" have very different protein content.

Pushing extra protein when the customer is not asking for it is commercial greed or ignorance (probably both).

p-value of 0.079? (Score:2)
There is a lot of backlash against p-values. I won't enter that argument here.
But, accepted standards are that p-values need to be below 0.05 in order to be taken seriously in a biological study, and, even then, they aren't that strong until they get substantially smaller. (Note that in physics, they've been burned so many times by crappy significance values that the standard there is 5 sigma, or about p = 0.0000003.)
This paper, according to the summary, reported an effect at p = 0.079. That's substantia
