Protein

Protein is essential for the repair and growth of muscle tissues. The amino acids derived from proteins form the building blocks for all cells in the human body. Without protein, your organs, hair, nails, immune system and every other part of your body would not survive. Those who work out need to supply their bodies with enough protein to carry out the bodies regular day to day functions along with recovering from your daily workouts. Daily protein requirements for active people have been disputed for years between sports medicine professionals and those who decide on the US RDA's. My personal opinion and that supported and accepted by most sports nutritionists and bodybuilding experts is 1 - 1.5 grams of protein per pound of body weight. This is a perfectly safe and very effective amount. Any less and your recovery and growth will suffer. Higher amounts of protein don't seem to be any more beneficial, either.

Best Protein Sources: Protein Powders and Supplements, Turkey, Chicken, Fish (White), Lean Red Meat, Egg Whites. 

Your protein intake should be approximately 30 - 35% of your total caloric intake. A 200 lbs male eating 3000 calories per day would want to consume 250 grams of protein per day, this would be 33% of his total calories. A 130 lb female eating 1950 calories per day would want to consume roughly 160 grams of protein per day, this would be 33% of her total calories. Your protein intake should be divided somewhat equally throughout all of your meals. If our 200 lbs male consumed 6 meals per day, he would want to consume 35-43 grams of protein per meal. If our 130 lb female were eating 6 meals per day, she would want to consume 20-30 grams per meal.
