Just as an example Berardi has mentioned the diet he followed when he first started in a few articles:
"In fact, how about an example? Being a very scrawny bastard, here's the crazy diet I followed to go from 140 to 210:
Breakfast 8AM: 6 whole eggs, 4 slices of whole grain bread, and 4 packets of instant oatmeal
Lunch 12PM: 1 pound extra lean ground beef, 1-cup cauliflower, and 2 large baked potatoes
Evening Meal 4PM: 1 pound of extra lean ground beef, 1-cup broccoli, and 2 large baked potatoes
Post-workout 8PM: 0.75lb of pasta (weighed before cooking), 1-cup green beans, and 0.75lb extra lean ground chicken
Before Bed: 6 whole eggs, 4 slices of whole grain bread
Also, upon waking each morning I'd mix up a one-gallon jug of water and somewhere between five and ten scoops of whey protein. In addition, I'd open a bag of six cinnamon raisin bagels and put peanut butter in between each bagel. The protein drink and the bagels were to be consumed all day long when an actual meal wasn't being eaten.
Again, the motto was, "If I'm not chewing, I'm not growing." I'm not lying when I say that as soon as I'd finish each meal, I'd start right away with my protein shake and bagels and continue on them until the next meal. Even if I was in class, even at work, even when I felt like I couldn't stomach another morsel. Wherever, whenever, I ate.
Now, with what I know now, I might've done things a bit differently, I'd have better balanced my fats. I'd have added a bit more fruits and veggies. I'd have mixed up some Greens+ into my protein shakes. Yet there's no question that I'd maintain the same calorie intake."
This is awesome advice for a beginner...because you need to understand the amount of food it takes to achieve the goals you dream about.

I believe strongly that the three most important principles in nutrition are quality, volume, and timing.
