Express Fat Loss and Protein Drinks 101
Posted on September 26th, 2011 1 commentQ: What is a protein drink?
A: Any drink with high protein content can be called a protein drink.
Protein drinks are often made by adding a protein source to fluid such as
milk, water or juice. A variety of commercial protein powders are available
for purchase at sport nutrition store.
Q: Why do I need protein?
A: Vigorous exercise and resistance training damage your muscle tissue.
While this damage is a necessary and normal response to physical exertion,
your body needs protein to repair it.
Q: Should I drink protein drinks?
A: The average person needs 0.8 grams of protein per kilogram of body
weight per day. This means that the average 70 kg male needs 56 grams of
protein per day. A UW student with healthy eating habits gets about 60 to 80
grams of protein in a day. However, if your eating habits are off track, your
body might not be getting enough protein. And most certainly not enough at
the right times during the day.
People who exercise at moderate to heavy intensity need 1.2 to 1.7
grams of protein per kilogram of body weight per day, or 84 to 119 grams of
protein for the average 70 kg male.
Protein drinks SHOULD NOT replace natural sources of protein. They
are used to fill the gap between what you eat and what your body needs.
Natural protein sources are flavored over synthetic ones. Snacks high
in natural protein can be just as convenient as a protein drink, e.g., chicken
breast and a banana, peanut butter and crackers, yogurt.
Q: When should I consume a protein drink?
A: As soon as you are finished your workout. Add a carbohydrate source
such as fruit juice for a more speedy recovery.
Q: Someone told me consuming a protein drink before
my workout is better than after. Is this true?
A: It’s best to fuel about 2 hours prior to your workout, and immediately
after. Your pre-workout fuel will include protein with a moderate glycemic
index carbohydrate food for optimal results.
This helps to keep your blood sugar stable while you work out. And,
research shows greater protein delivery to your working muscles.
Q: I went to my local sport nutrition store today. There
are so many different brands of protein powder, and
some are very expensive. How do I choose?
A: First of all, ignore the flashy “research claims” plastered all over the
product. These claims are often made based on research with flawed
experiment design. The health “benefit” claims are often glorified, and
potential risks may be minimized or ignored.
It helps to know a little about protein. Protein is made up of a long
chain of amino acids. When we consume a protein, it is broken down into
its component amino acids and then re-assembled into the kind of protein
our body needs. In order for a complete protein to be assembled, our body
needs 8 amino acids. These are known as the essential amino acids.
Any protein you buy should, at minimum, carry these 8 essential amino
acids.
The essential amino acids are: Tryptophan, Valine, Threonine,
Isoleucine, Leucine, Lysine, Phenylalanine and Methionine.
Many expensive protein powders claim to be superior because they
carry additional amino acids (there are 20 in total). Claiming these are
superior is false. As long as we have the 8 essential amino acids, our body
makes the other 12 when they are needed.
Many protein powders will also claim to be superior because they have
added “performance enhancing” vitamins and minerals. You may not need
these if you are eating well. At best, you are buying extra nutrients you
won’t use. On the other hand, over supplementing can cause problems. Be
wise and use only what you need!
Q: I read in a muscle magazine that if I am looking to
build muscle I should consume at least 300 g of protein
per day. Is this true?
A: There are mixed opinions regarding the maximum daily protein
requirements. While it is recommended that a person who exercises heavily
needs 1.7 grams of protein per kilogram bodyweight per day, it is not
uncommon for athletes to consume 2.2 grams per kilogram, and even more,
each day.
Most bodybuilding literature (such as the “muscle magazines”) will
suggest that an individual ingest 4.4 grams per kilogram (2 grams per
pound), however there is no scientific literature to suggest that this is
necessary, or even beneficial.
Excess protein is broken down and stored as fat. Over consumption of
protein can cause weight gain and also puts unneeded stress on the
kidneys.
Q: So if you could sum it all up, would you say drinking
protein drinks is good?
A: Yes. Protein drinks are a good source of quick protein post-workout.
They should be used as a complementary source of protein and should not
replace the natural protein you consume.
And, they make a great mid afternoon snack for those who more
sedentary. Try a protein drink, or make your own, and feel how it helps keep
blood sugar, and thus your energy, stable through the day!
