Carbohydrates :

As an athlete, carbohydrates are the major nutrients that give you energy. Everything you do in life requires a certain amount of carbohydrates, sleeping, studying, breathing, and training. Athletes who truly desire to become the top dog will stop at nothing to get the most out of the foods they consume and thus make wise choices as to what type of carbohydrates they eat.

Proteins :

Proteins received their name from the Greek and mean "to take first place." As nutrients, they actively build living nitrogenous tissue, they are the building blocks for all human tissue; if you do not eat them, you do not recover and rebuild after tough workouts. Plain and simple. However this does not mean the more you eat the more you rebuild/grow. Balance is the key to proper sports nutrition. Your body can only assimilate and absorb between 30-40 grams of quality protein per meal.

Fats :

Fats should make up a very small percentage of your whole diet, 15 percent or less. But nevertheless fats are needed, and you should not eat a fat-free diet, rather eat a low fat diet. Avoid saturated fats like they were cancer (because these are the fats that are attributed to causing cancer and cardiovascular disease). The best fats are plant based uncooked oils (olive, canola, safflower and flaxseed).
