Really good post hrdgain. Follow what he said...
Try to eat about 5-6 meals a day, including the shakes that he made reference to. I used to pirate food out of the caf all the time.
You'll have to eat on a rather consistent basis. I generally eat the same stuff everyday, day in and day out. A good resource to give you a ballpark estimate of how much calories, protein, fat, carbs, etc. is
www.fitday.com
There you can punch in what you ate and it will calculate everything out for you. This way you have a ballpark figure of how much you are eating,then modify as needed (add or subtract calories depending on how you are progressing).
At the end of the day, I know how much cals/pro/carb/fat I've eaten throughout the day. (yes, I measure and weigh). It takes some prep but goes a long way.
Hope this helps a bit.
