As you look through your social media, you’ll typically see your “fit” friends posting
their self-indulging pictures of their workouts, their progress, and of course, the supposed
healthy food they eat.
And undoubtedly, you’ll bump into the occasional post of the awesome protein shake they took
right before they hit the gym.
And by far the most popular protein shake comes in the form of Whey protein.
So, what exactly is whey and how can it help you with your fitness gains?
Whey is a source of protein naturally found in milk.
When mixed with rennant, a complex mix of coagulant enzymes, milk curdles and separates
into different constituents.
One is the aforementioned whey, currently in its liquid form and the leftover curds
are used to make cheese and also whey’s not-as-popular little brother known as casein.
The liquid whey is then pasteurized and dried out to create the familiar powdery product
we find in store shelves.
So, what’s in this whey that makes it so special?
The obvious stuff is the protein, and whey has quite a diverse amino acid profile.
It contains amino acids such as the common glutamine, the dopamine aide tyrosine, nitric
oxide booster arginine, and others such as lysine, glycine, phenylalanine, and aspartic
acid.
But in terms of building muscle, whey also contains the ever-crucial branch-chained amino
acids.
As we know now, the presence of BCAAs, especially leucine, in our body paired with resistance
training, immensely improves muscle protein synthesis.
And with about 3 grams of leucine per serving, whey protein most definitely can improve your
gains at the gym.
And the awesome thing about whey amino acids is that they form larger peptides and proteins
that serve more health benefits.
Perhaps the most beneficial for adults are the immunoglobulin and lactoferrin proteins,
which can aid your immune system, as well as having anti-cancer and anti-aging effects.
Whey protein is not exactly 100% all protein.
Being a dairy source, it naturally contains some fat and the sugar lactose.
As with any dairy product, this can problematic for those that are lactose intolerant.
Fortunately, there are different options.
Without getting too detailed on the different types of whey processing methods, just understand
that each process has the goal of isolating the protein in whey from the lactose, carbs
and fats as much as possible.
Problem is, some of the more intense separation methods, such as whey ion exchange and whey
hydrolysate, tend to “denature” the proteins, losing the added health benefits for the sake
of having more protein per gram and making the protein quicker to digest.
Whether you consider having more protein or having added health benefits more important
is your choice.
But the most common whey proteins found in stores are whey concentrate and whey isolate.
And if your main goal is gainz, these are some top-notch options.
For those that are not lactose-tolerant, whey concentrate has up to 80% protein and the
lactose can serve as a glucose source, powering your anaerobic energy system, thus, powering
your lifts.
For people looking for mainly protein or are lactose-intolerant, whey isolate clocks in
at above 90% protein with limited denaturation, and little to no lactose.
Also, keep in mind that most of these whey protein shakes will have added flavoring,
adding more sugar to its contents.
But now, you’re probably wondering, “Do you actually need whey protein in the first
place?”
The answer… again… as always, is “it depends.”
As great as whey protein can be, the protein in it can also be found in real food.
Your consideration largely depends on the amount of protein you’re already consuming.
If you’re already cranking down a solid amount of protein, such as .8 to 1.5 grams
per kilogram of bodyweight, then adding extra whey isn’t going to make a huge difference.
Now, if you’re trying to lose body fat and preserve lean mass at the same time, whey
supplements might help you meet your protein goals without the additional calories as well
as helping you feel more full throughout your day.
For every other goal, it should be considered as a matter of convenience.
Sometimes reaching your daily protein intake with food can be understandably difficult.
Chugging down a whey protein shake can be easier than chomping down two pieces of chicken
breast.
Ultimately, you should think of whey protein, or any other protein supplement for that matter,
the same way you think of the protein you eat.
They are essentially the same.
With that being said, if you feel like your gains have been better with drinking a protein
shake, then continue to do so.
If you don’t think it will help you, simply don’t take it.
The choice is up to you.
