These numbers are actually "disappearance" they include an immense amount of food waste as well so the average American is probably almost half a body builder and leaving food on their plate at a restaurant while more of it is going bad at home and in their grocery.

yeah, and it’s also worth noting that the usual guidelines you hear like “eat 1g of protein for each pound you weigh” are actually meant to be 1g of protein per pound of lean mass, which for many people is significantly smaller amount.

1.5g/kg for a 90kg person is 135g. You can get almost half that daily need from a chicken breast or a few ounces of fish. Two meals of that and a few non-meat things like rice and beans, lentils, peanut butter, etc and you're set, even towards the higher end of the recommended range. That's doesn't seem outrageous at all.

I think most commenters are missing two things:

1. It’s proteins and fats, not just protein. The site specifically calls out avocado as an example.

2. It’s from meat and vegetable sources. Other commenters have mentioned that you get more protein from non-meat sources than you expect.

People are also forgetting the importance of fiber for satiety and gut health.

And here I am thinking that 50-100g of protein per day for an elderly person was way too low.

But here we have the problems with the numbers and why they should only be guidelines. Consumption of protein needs to increase as you get old (into the range we consider for athletes). And basing consumption on body weight is stupid, because telling an obese person they need to eat twice as much protein as a non-obese person is probably wrong.
