This article is a great read; bringing forth common sense, knowledge, and understanding of our instinctual drive for meats, nuts, and fruits in bodybuilding.

The writer, Paul Burke, has an amazing physique for a 50 year old gentleman.  He attributes his success to vigorous training and a diet that is closer to the Paleolithic diet of long ago than that of modern man, with lots of protein, meats, nuts, fruits, and veggies.

"So, now, we must use logic: What happened? It's simple: The lifestyle of the hunter-gatherer made them strong and powerful; but more importantly, what they ate: wild animals and wild nuts, wild vegetables and wild fruits. These where the reasons for their massive stature."

"Wild, wild, wild! The more an animal moves the more energy you get from it; both in the form of protein and carbohydrates (in the muscle tissue) and the energy that never dissipates from a living thing. When you eat a cow that is stuck in a metal harness all its life that just eats and eats and defecates; then you have no wild energy, no life force to take from it; in fact you get a cow full of drugs and fat as of the past 20 years. However, if you eat a wild deer, a new "Free Range Buffalo," then you are going to get not just protein and carbohydrates, but that invisible, unquantifiable life-force. Now that is what made our great Neo Paleolithic ancestors such muscular marvels..."

... Small meals spread out does many things, but the two major ones is it keeps insulin levels down and it keeps a steady flow of protein coming in forming a positive nitrogen balance: this leads to muscle mass and the more muscle you have the more fat you burn and the longer you live because unless you have a heart attack you cannot die with a lot of muscle. It is a buffer against aging."

Paul makes a good point of relying on his body for energy rather than relying on foods, such as processed carbohydrates and sugars. 

As you embark on your journey to a strong muscular body, don't skimp on the protein, do your body good and divulge in plenty throughout your day.
