i am 20, training for 7 years (height is 5'11"). i work out 4 times a week and also perform 2 additional cardio sessions per week, one i do sprint running, basically emphasis on improving my 2km time which is currently 6:50, after the 6:50 that I do the 2km i continue running until i reach about total of 22-25 minutes. the other cardio session is long duration running 12km for about 55 minutes or so.
my work is mostly sitting on my ass in front of the pc for 12 or more hours a day with the casual breaks to heat up the next meal in the microwave

honeslty up until half a year ago or so I would not consider myself having fast methabolism as I have always been skinny/fat, however as i constantly started doing cardio and sticking to it for 6 or more months now it does indeed appear that i can get away with much more than i originally thought, although my diet is generally considered of complex carbs and proteins in every meal.
thinking again i dont feel as lightheader but more like i have this annoying "sucking" feeling in my stomach like its empty and needs some food to break down..
as for posting a pic on getbig id rather not, i feel im not on that level yet (must npc level atleast

to take a verbal beating by legeds like the squadfather here
