While working out and transforming your body, a commonly overlooked factor is diet. Sure, working out hard will allow for some change in your physique, but the true task is to feed your body the necessities it requires for gaining lean muscle mass, decreasing body fat and keeping up the energy level for these extra activities.

Now, I'm not talking about the diet you get out of a can or in a pill, or the one that limits your food choices to one food group (or one food!). I am talking about smart food choices; a lifestyle change that is fairly easy to adjust to and one that anyone can live with.

Have you ever seen a person who works out like crazy, but never looks any different? I think every gym has one of these. These people are not doing one of two things: varying their workouts (see The 16 Most Advanced Intensity Building Techniques!), or are not making wise food choices. It is likely the latter, where they have not been taught the basics?

Here, I will detail the very simple science behind food choices and how to incorporate them by choosing from simple charts of the food option examples for the different nutrients our bodies need. Keeping in mind too, that it is okay to indulge sometimes, but a lifestyle change of healthy eating will not only ensure a maintained physique, but also healthy insides for disease prevention. Use these basic nutrition tips to help you get started and you will be sure to achieve the success you have been looking for.

Note: When starting a new program of any sort (diet or exercise) be sure to consult with your physician first.

The Muscle Nutrient: Protein

It has been said that protein is the staple of any diet, especially to serve the dietary needs of an athlete. Next to water, protein is the most abundant material in the human body. It is present in muscle, bone, connective tissue skin and blood.

While consuming enough protein is essential for growth and development of the body, eating huge amounts will not build muscle unless you are strength training at a high intensity in order to cause muscle hypertrophy (muscle growth). This means you should not fall into the high-protein fad that seems to be the latest trend in North America.

The following is a protein recommendation list based on the current Recommendation for Dietary Allowance (RDA):

• Sedentary or those who exercise infrequently = 0.4 grams / 1 pound of body weight
• Active exerciser = 0.5-0.6grams/1 pound of body weight
• Very active/weightlifter/endurance athlete = 0.7-0.8 grams / 1 pound of body weight

In general, about 15-20% of your total daily calories should come from protein.

Here is a list of some good sources of protein to get you started:

• Chicken breast
• Turkey
• Orange roughly
• Salmon
• Tuna
• Top round/sirloin steak
• Lean ground beef
• Egg whites
• Low fat cottage cheese

The Energy Nutrient: Carbohydrates

The supermarket shelves are filled with tons of "low carb" items and every new fad diet screams to 'cut the carbs, pass those potatoes and resist the rice'! Low carbohydrate diets will ultimately affect your stamina and endurance, so they are in fact necessary since they are the body's main source of fuel.

Carbohydrates fuel the body by providing our muscles with glycogen, while working out, and helps us to optimize our athletic performance. Carbohydrates should be from minimally processed sources like eating true whole wheat bread versus white bread or even enriched bread (read labels carefully - sometimes the brown packaging or the name "health/12-grain" bread can be deceiving).

Carbohydrates should make up about 55-60% of your total caloric intake, depending on your activity level.

Here is a list of food sources of carbohydrates to help you:

• Baked potato
• Sweet potato
• Brown rice
• Wild rice
• Squash
• Pumpkin
• Oatmeal (whole oats)
• Whole wheat bread/tortilla

The Essential Nutrient: Fat

Fats are an important and necessary nutrient for everyone. That is, some fats - you see, there are those that are saturated and are not good for your cholesterol levels, potentially causing clogged arteries.

The fats that are considered good for your body are unsaturated fats. These can actually help protect against heart disease by reducing cholesterol and providing the body with extra energy. Basic rule here, if it is a solid at room temperature, it is usually saturated (bad) ; if it is a liquid at room temperature it is unsaturated (good).

Of course, here is a list to help you with some of the good fats you should include in your diet:

• Safflower oil
• Olive oil
• Flax seed oil 
• Sesame oil
• Fish body oils (EFAs=essential fatty acids) 

The Hydration Nutrient: Water

Drinking water during exercise is necessary to sustain performance and to avoid injury. What to drink and how often to drink it really depends on the duration and type of workout you are doing. There are some activities like long distance running which may require more than water (sports drinks help to also replenish lost electrolytes).

A general hydration rule is to drink one 8oz glass of water for every 15-20 minutes of exercise.

Making Your Transistion Easy

Now that you are armed with your food basics, you can incorporate this into your existing regimen to achieve a healthier lifestyle.

Below are some other quick tips to follow to make this transition more easily:

• Eat smaller meals more frequently throughout the day to feed your metabolism and raise it naturally, so you are able to burn calories at a more efficient rate.
• Prepare foods in advance so when you are "starving hungry", you are less likely to eat junk.
• Season meats/fish the night before so that they are tastier when cooked.
• Don't deprive yourself; if you crave chocolate chip cookies, have one or you'll end up eating an entire bag tomorrow!
• Chew slowly and serve small portions at a time so you stop eating when you are full.
• Do not skip meals - this sets you up for overeating.
• Keep a diet journal so you can stay on top of your new lifestyle change.
