Protein: What Is It and Why Should You Care?

Proteins function as the building blocks of your body. They’re used to make muscles, skin, tendons and organs, as well as hormones, enzymes, neurotransmitters and many other compounds that are crucial for your health and well-being.

In addition to these critical biological functions, getting enough protein daily also helps you obtain and maintain your ideal figure. Here are just three of the many benefits that getting adequate protein has on your physique:

  • Boosts fat loss

Eating more protein helps with obtaining and maintaining healthy body weight. For example, one study had 19 subjects increase their protein intake from 15% to 30% of their daily calorie intake. Without making any other dietary changes, they automatically consumed an average of 441 fewer calories per day, which led to an average weight loss of 11 pounds in 12 weeks! (1, 2, 3).

  • Curbs hunger

The primary reason why eating more protein helps you lose weight is that it reduces total caloric intake by slashing appetite and raising satiety. It does so by increasing levels of the satiety hormones cholecystokinin, GLP-1, Peptide YY, while lowering the hunger-inducing hormone, ghrelin (4, 5, 6, 7).

  • Supports muscle mass

It’s well-documented that getting enough protein aids muscle growth and strength. Besides, it also prevents muscle loss if you’re on a weight-loss diet. This not only keeps your sex appeal buzzing but also benefits your metabolism since muscle is metabolically active (8, 9, 10).

Here’s what to do…

To experience the life-enhancing benefits of protein, consume between 0.8 and 1.2 grams of protein per pound of body weight. So, if you weigh 170 pounds, get between 136 and 204 grams of protein daily. If you don’t reach that target by diet alone, a high-quality protein powder can be the perfect solution.

How to Choose Protein Powder

There are many protein powders on the market. Variations in the source type include whey, casein, egg white, collagen, beef, soy, pea, hemp, and rice – just to name a few.

Now, if you want optimal results, then it’s crucial to select a protein powder that’s optimized for your goals and needs. Here are the four best options if you are following a ketogenic diet:

1. Whey Protein Isolate

Whey protein is the liquid that remains after milk is curdled and strained. This protein-rich liquid then gets spray-dried into a powder and undergoes microfiltration to create whey protein isolate. Whey protein is excellent for many reasons.

First off, it’s the fastest-digesting protein powder, which means that the amino acids reach your bloodstream most quickly. This makes it an excellent post-workout solution. Besides, whey protein has an excellent amino acid profile.

It’s particularly rich in leucine, an amino acid that plays a crucial role in stimulating muscle growth. Whey protein, along with casein, have the highest bioavailability of all protein powders. And it’s the most affordable option (11, 12, 13).

2. Casein

Like whey, casein comes from milk. The main difference, however, is that casein digests more slowly since it contains gel-forming capabilities that slow down intestinal motility and absorption speed. Casein has a top-notch amino acid profile and bioavailability.

And because casein digests slowly, it’s satiating effects outlast those of whey, egg white, beef, and protein powders from other sources. That’s why it’s the best option for curbing hunger and promoting weight loss. For the same reason, casein powder is also good to take before going to bed, as it will supply your body with amino acids throughout the entire night.

3. Egg White

Egg white protein powder is made by first separating the egg white from the yolk, after which they undergo dehydration and pulverization. The end result is a highly bioavailable protein-rich powder with an excellent amino acid profile.

Egg white protein digests at a moderate speed. So it stimulates protein synthesis (muscle growth) and curbs hunger for a more extended period than whey but not nearly as long as casein. Egg white protein is excellent for those who can’t consume whey or casein due to a dairy allergy or lactose intolerance. Besides, it’s free of carbs; is relatively cheap; and contains considerable amounts of vitamins A, B, and D (14).

4. Collagen

Collagen is the most plentiful protein in your body. It’s found in nearly every tissue, including your skin, muscles, bones, and tendons. Consuming enough collagen can boost your health and well-being in many ways.

For example, researchers found that collagen can increase skin moisture, reduce wrinkles, slow down skin aging, boost hair growth and thickness, support cardiovascular health, and improve joint health (15, 16, 17, 18, 19, 20).

Collagen protein does, however, have one downside: it lacks certain amino acids, such as leucine, that are crucial for muscle growth. That’s why collagen is not optimal for increasing muscle mass. But from a pure health-perspective, collagen is hard to beat.

Note: plant-based protein powders are not recommended because they have an inferior amino acid profile (either incomplete, too low in leucine, or both). And beef protein powder isn’t recommended either since it’s derived from the discarded parts of a cow –such as bones, hooves, skin, joints, connective tissue, ears – which not only sounds gross (at least, to us), but also results in an inferior amino acid profile.
