If you wanna grow, eat. Red meat, eggs, potatoes, pancakes, pasta, rice (don't listen to anyone--it does not matter whether it is white or brown), chicken, and, believe it or not, bread. These are some of your friends. These are the friends you should be hanging out with anywhere between 6-8 times a day. Go out, have a beer and relax… Try to get laid--it is a good de-stressor.
EAT_EAT_EAT_EAT and EAT again and again and again
