As long as you haven't radically changed your diet recently I think you can handle your protein requirement pretty much intuitively, simply by adhering to your appetite. When I have done some heavy, muscle building exercise, I always tend to crave protein. So I give in to that craving and have e.g. a heaping of scrambled eggs with cottage cheese (a protein shake should do the same, but I'm not used to it so my appetite doesn't relate it's taste to the protein content). That usually makes me feel fully satisfied, the craving subsides and I proceed with my usual low-animal protein diet.
I think this intuitive approach works actually pretty well, as long as you generally follow a decent and varied diet. It may not work so well for someone following a vegan diet (because that excludes all the animal protein sources we have evolved with) or for a professionol athlete or die-hard bodybuilder, because in this case one absolutely has to make sure to get the maximum amount of lean muscle mass buildup.
Howewer, despite of what many bro-science and paleo bloggers want you (and themselves) to believe, extreme bodybuilding and longevity don't agree very well. By pumping up your muscles and skyrocketing your testosteron levels, you may actually do what primal evolution likes you to do: maximizing your strength and reproductive capacity. But that comes at a cost later in life, once your offspring would have been raised and, as an individual, you fall from Nature's grace.
That said, some sensible, fitness-oriented bodybuilding is liekely benefical and it is OK to temporarily increase your protein intake to support muscle building phases. Just don't carry it to the extremes and don't eat a high protein diet for most of the time.
I've cut back on the eggs. I'm having them once a week now--if that. I am training and the protein shakes are temporary while I'm in this particular phase. For lunch I'm having a Salmon salad and for dinner I'm going to alternate a vegan and lamb stew in the slow cooker. Not sure about breakfast though. Subjectively, I feel good when I have the macadeimias, and they keep me going well until lunch. I tend to get fat quick on musli and any other cereals in the morning. Apart from the macadeimias, it's hard to think of better breakfast. Any suggestions?
Sounds good. Nuts for breakfast are great, too. Note that with muesli I don't mean processed and high GI breakfast cereals, but rolled whole grains, fruits, nuts and seeds. This is what my muesli looks like.
