That measure is for when you are specifically looking to build muscle I believe, which might be a bit orthogonal to direction you want to go (if for weight loss).
It is also, IMO, a lot of protein to consume a day. I personally have never done that level of protein intake, ever, but I know a few who have, its an insane (to me) amount of protein powder, chicken, and broccoli (or alternatives) you have to consume, every day. If the goal was sustainability, it's definitely not possible for average people.
