Carbohydrates have been getting a bad rap
lately. They are what the body desires for fuel and what makes it run the most
efficiently. Unfortunately, when improperly consumed, they can lower the body's
metabolism and lead to the risk of either malnourishment or weight gain. Here
is a quick rundown on what carbohydrates do, where you find them, and how to
get the most out of their consumption.
Carbohydrates are a chemical
compound of carbon, oxygen, and hydrogen. Common forms are starches, sugars,
cellulose, and gums. They are more readily used by the body for energy than
fats and proteins. They can be classified as "simple" or
Fiber is mainly an indigestible complex carbohydrate that
makes up plant cell walls.
Complex carbs are found in whole grains,
vegetables, nuts, some fruits and legumes. Incidentally, alcohol breaks down in
your body as simple sugar. Most of your carbohydrate consumption should come in
the form of complex carbs. Sugar, the most common simple carbohydrate, should
be avoided in most cases.
When you consume carbs, your digestive system
converts them to blood sugar (also known as glucose), which is stored in your
muscle cells and liver. Your brain operates with the help of glucose in your
blood as energy. When your training is intense, glucose stored within your
muscles provides most of the energy for muscle movement. But when your body has
all the energy it needs to store for muscle movement, the remaining carbs are
stored as fat! YES... FAT!
As you can see, the key is learning how to
take in just enough carbohydrates and not too many. This can be tricky
An athlete that needs to perform at a high-intensity output
will obviously need more carbohydrates than a couch potato. But even sedentary
people need some carbs. Your body burns carbohydrates all the time. When it
doesn't have them, it turns to stored body fat. Now, this may sound like a good
thing (and usually is!), but you should not force your body to do this always.
It is not efficient and you will never get a maximum performance out of your
body - and remember, this includes brain activity! The process of using stored
body fat for energy is called ketosis and can be dangerous over prolonged
periods. However, it can also be trained to where your body gets efficient at
using stored body fat for energy, and that means exercising on an empty stomach
at moderate intensity, but not moderate in duration.
BeachBody.com recommends that your diet be close to 30% protein, 30% fat, and
40% carbohydrates. There are various theories about this ratio, most notably
the research of Nobel Prize winner Dr. Barry Sears of "The Zone." But at the
same time, some people with extremely high activity levels can consume carbs
with no body fat consequence. (Bicyclist Lance Armstrong consumes around 80%
carbs during events like the Tour de France and his body fat stays at 3%!)
Experiment and see what works for you. A good way to start would be to cut way
down on carbs and then slowly start adding more until you find the perfect
energy point for you - with few highs and lows, but also no sustained
Once you figure out the amount of carbs your body processes well,
you will be able to gauge your diet decisions so that you do not eat so many
carbs that you store them as fat, but so few that you are not getting enough
energy for brain function.
