1g/lb is in fact a popular target among bodybuilders.

Much research indicates 0.5 to 0.7 g/lb provides most of the benefits, with continuing but diminishing gains above 0.7 g/lb. And the benefit is not just for "body building", but also for minimizing muscle loss during weight loss and improving insulin sensitivity. Other research indicates we may benefit from higher levels as we age.

quite off!

You need at least 0.8g / kilo (referring to 0.4g / pound) if you are doing nothing heavy, like walking to the office.

If you do moderate sports, you are hitting 1.0g / kilo immediately.

If you do some more extensive sports, like 3 - 4 days / week in gym, you jumü to 1.2 - 1.4g / kilo.

Bodybuilders are quite above :-))

Regarding the number of chicken breasts - scary for me, Im enough with a half one every second or third day.

There was a great movie about vegan & bodybuilding with known sports people: The Gamechangers - https://en.wikipedia.org/wiki/The_Game_Changers

I am not sure if you're disagreeing with the original poster here but you're both saying the same thing in different units. 1g/kg != 1g/lb which is A LOT more protein and a complete waste of time. As a mostly vegetarian who lifts regularly, I am targeting a bit more than 1g/kg but being from the US it is a lot less than 1g/lb. :p

maybe I was wrong? 1 pound = 500g 1 kilo = 1000g

therefore, multiplied by 2, though the numbers I showed are higher

It’s not recommending 4 to 5, but for larger people (I’m 200lbs) to hit their protein target I’d need to eat over 1lb of chicken a day which is a lot.
