As a guy who can not face breakfast other than coffee with the occasional cigar, I rely on a protein shake for after my 2 and sometimes 3 mornings/wk of powerlifting. I don't know anybody who can or wants to eat food after a morning workout.
People ought to get about 20 gms of protein after a heavy weights session, so a good breakfast for heavy lifters (but not body-builders - not talking about them) would be a couple of hard-boiled eggs unless they are trying hard to put on weight. I can't stand solid food in the morning, so I do a protein shake (from Amazon) after a lifting hour and after a very tough calisthenics class too when they include more weights.
I throw some frozen berries or a banana in the blender for a little carbs etc. I use the vegetable protein powder cuz I became lactose-intolerant. Funny, tho - I seem to tolerate ice cream just fine...but I do not need to lose any fat anyway since Mrs. BD says I am "cut". I suspect I am naturally pudgy like one of my grandpas, but that's not going to happen. My Dad was 6'4", lean, and hard as rebar, but I sadly didn't get that gene. Gotta work with what we get.
With my daily workout plan (6-7 hrs/wk), I am supposed to have two slices of chicken or meat mid-day, and an apple or some raw vegetables. I try to do that too, but any mid-day food makes me sleepy and lazy. Not good for being productive and useful.
Real athletes who workout 4+ hrs/day have entirely different nutritional demands. At Maggie's we just address us ordinary fitness folks. Sedentary people? They do not need much food at all but, curiously, they have greater appetites than active people. Probably recreational/boredom/ritual feeding. Something to do.
