> ~0.82g/lb of lean body mass

That's 1.8g/kg of lean body mass which is pretty close to the 2g/kg total body mass I've always used for weight training.

That's still a LOT of protein. 130g a day for me. To reach that is 500g of chicken breast, for example. And it's not like you can eat that in one meal. That's another controversial topic but it's likely about 50g per meal (for me, 90kg man) is the max. So if I eat chicken for dinner, 50g protein the I still need two other spaced meals to get the remaining 80g.

I'm not doing elite training so I'm not going to follow this rigidly, it's just a rough daily goal. I'll usually have a protein shake per day, then a high protein meal and try to make up the rest elsewhere.
