This is a good range for improving for maintaining your body composition; preserving or building muscle. Fitness coaches are recommending 2.2g/lb (1g per lb) or even more which doesn't have much scientific backing. 1.6g/kg seems to be the max that will benefit muscle gain.
On the other hand, there are some (Valter Longo, biologist at UCLA) who say that such high protein will reduce your overall longevity. He recommends 0.36g protein per lb body weight.
I don't know what to do with this info. Personally, I stay around 1.2g protein/lb (and exercise) as a middle ground.
