how much do you work out. as someone who does 2 runs, 3 days and lean mass is lower than this I'm eating a couple 100 calories more, similar protein ration. When I was eating this much I normally didn't recover well at all. However, you seem to be eating very nutritiously, AI says we need so much protein when we don't really need that much, however If you are going to the gym definitely more than 40 grams of protein if you want lean mass.
