The Athletic Performance Diet
Interestingly the athletic diet has changed very little over the
years. The reason being is that there are not many pathways to
fueling the body most efficiently. A diet consisting of 60-65%
carbohydrate, 20-25% fats, and 15-20% protein is the proper
ratio of macro nutrients for most athletes and has been the
mainstay for years. A highly trained endurance athlete would not
last very long on a high protein diet, because their glycogen
stores would quickly become depleted and they would no longer
have the energy or reserves to train effectively. There is
little controversy in athletic nutrition when compared to the
general population. I believe the reason for this is athletic
nutrition is based on hard science and fact, rather than
sensationalism and circumstantial evidence. Coaches rely on
clinical studies and proven methods rather than the latest hype.
Remember, most diets have to have a "hook" or gimmick to get you
to purchase their plan or products. That is not to say there is
not hundreds of performance enhancing athletic supplements, many
with dubious value. But the overall big picture on how to fuel
an athletes body really has not changed all that much. This is
what most athletes should focus on, rather than the latest
supplement, performance enhancing product, or fad diet plan.
Complex carbohydrates such as starches and fiber should be the
cornerstone of the athletic diet. Complex carbohydrates include
breads, pasta, cereals, vegetables, rice and other grains, and
potatoes. I try to choose carbohydrates that are in there
"natural" form such as whole grains because they have more fiber
and nutrients, and give a slower steady release of energy. If
you are trying to loose weight, these foods have the added
benefit of requiring more energy (calories) for break down.
Processed carbohydrate foods such as pasta and bagels are great
for loading your body with energy before and after competition.
Simple sugars are good during a competition and for quick energy
replacement afterwards (sports drinks). I try to avoid fruits
before competition. They can upset your stomach and the type of
sugar, fructose, can be harder for your body to process during
exercise. Carbohydrates are broken down and stored as glycogen;
the bodies fuel source, or converted to energy to compete and
train. When glycogen stores run out you may "bonk" or "hit the
wall." You feel lousy, lethargic, and slow. Your body begins
breaking down your muscles to use as fuel. Several days of hard
training can also deplete glycogen stores. This sluggishness and
inability to train hard is often misdiagnosed as overtraining. A
good post work out recovery plan is crucial to maintaining
glycogen stores for repeated training and competition. This
means eating carbohydrates and a little bit of protein (4:1
ratio), immediately after training.
Fat is also a fuel source used during training, especially at
lower intensities. But fat can't be broken down very fast. As
the intensity of exercise increases carbohydrate becomes the
main fuel source, but the total amount of fat burned can remain
the same, and the calories burned will be much greater. Don't
fall into the fat burning "zone" exercise plan. Fat is not a
good source of energy to consume during exercise, but is crucial
to processing certain vitamins and performing body functions.
The best fats are mono / poly unsaturated fats. A good way to
remember these types of fats is that they are liquid at room
temperature (oils), and generally come from plant sources.
Examples are avocados, canola, olive, safflower, and other oils,
and nuts. Saturated fats generally come from animal sources and
include cheese, lard, butter, meat fats, and cream. Your body
only needs a small amount of saturated fats; about 10% of your
diet. These are considered your "bad" fats that can raise
cholesterol.
Protein is a poor source of energy and requires a lot of work to
break down. Protein only supplies about 5% of energy during
exercise, and up to 10% when glycogen stores are depleted.
Protein however is crucial to repair the muscle damage of heavy
training. There is evidence that endurance athletes need even
more protein than body builders. Don't fall into the
protein=muscle trap. Muscle gain comes from adaptation to stress
(ex. weights), and proper nutrition. Consuming too much protein
can be hard on your kidneys and is unnecessary. Your body can
only process so much protein at a time; the rest is flushed from
your body.
If weight loss is you goal focus on energy in and energy out-
calories. Do not fall victim to fad diets. Weight loss is really
just a numbers game; you have to burn more than you consume to
create a deficit. Remember; Lance weighs his pasta. A round
number for weight loss is 10 x weight + 2 x weight for men, and
10x weight + weight for women. This is roughly your resting
metabolism, the number of calories your body needs daily to
sustain bodily functions. This is less than the number of
calories your body burns every day. Couple this deficit with the
deficit created by exercise, and you will loose weight. It is
preferable, however, to loose weight by the deficit created from
training only. This way you do not have to worry about being
depleted for training. Eating smaller meals throughout the day
can boost your metabolism and keep you from over eating. Try not
to go hungry; you tend to eat too much at one sitting when you
are hungry.
The "big picture" is to try to make sure each meal has
carbohydrates, fats, and protein in the approximate ratios. Make
sure your diet is balanced and consistent. You can do this by
quantifying and calculating your food choices, or by simply
eyeballing your plate. Eat a variety of complex carbohydrates,
low fat proteins, and healthy oils. Stay away from high fat
foods, especially saturated fats. It is important to read labels
so that you know what you are putting in your body. Consider
yourself as an athlete. Athletes' put grade A high octane fuel
in their bodies because it gives them a competitive advantage.
