What kind of nutrition should you consume to be a bodybuilder?  Most bodybuilders follow strict diets for the better part of the year that consists of good sources of protein, complex carbohydrates as well as unsaturated fats.  Protein being one of the most important macros can come from sources such as lean beef, chicken, turkey, fish and in the form of protein shakes.  You should consume 5 to 6 meals per day with a small portion of protein from these sources daily.  Generally most active atheletes and bodybuilders will consume around 1 gram of protein per pound of bodyweight.  When consuming carbohydrates make sure the portions are also small.  Try not to eat more than the amount you could fit in the palm of your hand.  Stick to sources that slow digesting and will dramatically raise blood sugar levels such as sweet potatoes, brown rice, whole wheat pasta and oatmeal.  Protein and carbohydrates should make up 80% or better of your total calories while the remaining amount should come from healthy or unsaturated fats.  Fish Oil, Flax Oil, Olive Oil and nuts are great sources to acheive these.  These essential fatty acids have been studied extensively for improving cardiac risks factors and are important to help maintain a healthy diet.

Consuming 5 to 6 meals in this manner can be quite time consuming so preparing your meals and planning in advance are necessary to stay on track.  If you can cook and prepare 3 meals, the other meals can come in the form of meal replacement shakes and bars so that its more convenient.  Taking 1 day week to cook all your food will help out a lot.  For instance on Sunday you could fire up the grill and cook 8 to 10 chicken breasts, lean steak and turkey burgers all on the grill.  You can even cook your vegetables at the same time.  Store the food in tupper ware containers and stick them in the fridge.  Without having this food on hand at all times you will resort back to eating unhealthy and try to find something quick thats good for you or your waistline.
