The main factor in protein utilization is insulin sensitivity. High insulin sensitivity allows you utilize maximum protein from minimum food. If your goal is is sustainability don’t even bother about your protein. If however your goal is to gain muscle gradually increase your protein intake until noticing results. Remember your training is a critical factor too. I am not a big believer in counting protein per body weight. Use your instincts and common sense, enjoy your meals and even more so enjoy your life. Counting protein is unnatural and unnecessary.
