Eat. Lift. Sleep. Repeat.
I liked supplementing my diet with 2 shakes per day of Cytosports Cytogainer. My normal diet included eggs and oatmeal at breakfast. A lean lunch focusing on quality protein sources (tuna or chicken in most cases), and fresh veggies (raw broccoli, mostly). Dinner was also built around ample protein sources and veggies. Usually on lifting days I'd eat about 1.5 cups of fat free cottage cheese with a whole avocado shortly before bed. I wasn't too strict, but one thing I did really concentrate on was eliminating processed snack foods like doritos or pretzels and basically every drink except for milk or water.
I'm currently 6'2" and about 230lbs, but I'm trying to cut that down to under 220. I was up at about 240 not too long ago.
