The Ultimate Guide to Understanding Whey Protein

Whether you are looking to take on muscle mass or drop a few extra pounds, there are probably a thousand different methods out there that claim to be the best method. But we are learning more about one method that is showing tons of benefits: using whey protein.

This guide will take you through the complete understanding of just what it is, the different types, the benefits it can provide for both muscle mass and weight loss, and so much more. By the end of this guide, you will become a whey protein expert.

Ready to go? Let’s dive in to learn everything there is to know about whey protein and what it can potentially do for you.

What Is Whey Protein?

One thing that you may not have known is that milk contains two types of protein:

  • Casein Protein
  • Whey Protein

Casein makes up 80% of milk’s protein levels while whey accounts for the other 20%. When cheese is produced, the whey gets separated as a byproduct.

During the separation process, it goes through several steps to become a powder that is ultimately added to shakes, protein bars, and meal replacements as an additional source of protein. But since it doesn’t taste very good on its own, it generally comes in a number of flavored powders such as strawberry, vanilla, and chocolate.

Types Of Whey Protein


There are also several popular types of whey protein to be aware of with the main difference being in the way that they are processed. The three types of whey protein are:

Whey Protein Concentrate


Concentrate whey has about 70% to 80% protein levels and contains some fat, lactose, and generally has the best flavor to it.


Whey Protein Isolate


This has a higher protein content at 90% or higher, but also contains far less fat and lactose and also tends to lack many of the beneficial nutrients that are found in whey protein concentrate.


Whey Protein Hydrolysate


This is also known as hydrolyzed whey. It has been predigested so it actually absorbs into your bloodstream. Be cautious of this type of protein as it can also cause a 28% to 43% greater spike in your insulin levels than the isolate type of protein.


Concentrate tends to be the most common whey protein on the market because it is the least expensive and retains the most beneficial nutrients that are found in whey. It is also the best tasting option out there due to the fat and lactose that comes in it.

Muscle and Strength Benefits

Perhaps the most well-known use of whey protein supplements is in the building and increasing of muscle strength and mass. Needless to say, it is popular among bodybuilders, athletes, fitness models, and people that are looking to achieve greater performance at the gym.

There are a few ways that whey protein promotes strength gain and muscle building. The first is that it has the necessary amino acids and protein that the body needs as building blocks to increase muscle growth overall.

Whey is also great for increasing the release of anabolic hormones. This promotes stimulation for muscle growth and can result in increased insulin in your body. There is also a high content of the amino acid leucine which stimulates muscle protein synthesis at the genetic and molecular levels.

Lastly, it is absorbed quickly. This means that it is utilized by your body in short order so that you can get the effects faster than other kinds of protein. Whether using before, during, or after a workout, protein has a great impact on developing and improving muscle mass.

Supporting Weight Loss

Perhaps you’re not really looking to build muscle right now with a focus on dropping pounds instead. It is well-known that protein can actually aid in weight loss since it is by far the most satiating macronutrient out there.

Because protein can boost energy expenditure substantially, that means it can also lead to far fewer calories taken in; a whopping 441 fewer calories per day. This also means cutting cravings by a whopping 60% and reducing the desire for late-time snacking.

This kind of protein intake, which replaces some of those unhealthy calories, can not only lead to sated cravings, but increased performance in the gym. This can lead to substantial weight loss in short order while increasing that lean muscle mass that many desire.

If you have been trying to lose weight, adding a whey protein supplement to your diet can help you get rid of that pesky fat and hold on to the muscle that you want instead. Implementing whey protein can make for a huge difference in weight loss game plans, changing the way that you diet.

Other Benefits

In addition to its benefits as a weight loss and muscle building supplement, whey protein contains many other beneficial nutrients. This can include beta-lactoglobulin, lactoferrin, immunoglobulins, and alpha-lactalbumin.

In addition to the strength, muscle, and leanness benefits, there are actually health benefits to using whey protein. This can include things such as lowering blood sugar, blood pressure, and reducing the symptoms of stress and depression.

Crazy as it sounds, it can also help to protect against cancer, increase bone mineral density, reduce symptoms of hepatitis, and improve the immune function of HIV patients. This is likely due to the fact that it is high in the amino acid cysteine.

Cysteine achieves all of this by raising the levels of glutathione in the body, which is the main antioxidant in your body’s cells.

Really, there is almost nothing that whey protein can’t do to better your life. Even if you are taking it for the weight loss or muscle gaining benefits, you are also getting the kind of health benefits that would make it worth trying by itself.

Try implementing whey protein into your diet for all of these reasons and begin to see a real change unlike ever before. You will be surprised at what whey protein can do for your body and the numerous ways that it can benefit you in the long run.
