I get that I include some rice, peanuts etc. in there, but even if I quit EVERYTHING else there's no way 4 to 5 chicken breasts a day is accurate.
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
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.
therefore, multiplied by 2, though the numbers I showed are higher
