Are Whole Eggs Better than Egg Whites for Muscle Growth?

Posted: Written by:

Your alarm goes off.
It’s the crack of dawn.
You head into the kitchen.
Turn on the coffee pot.
Crack a couple of eggs and pour some liquid egg whites into a bowl.

Then that beautiful sizzling sound happens when you have the frying pan on medium-high and you pour your eggs onto the pan.

As you are scrambling your eggs, you scroll down your phone and see a headline from the New York Times saying, “Whole Eggs are Better for you Than Egg Whites.”

You think “huh?”
I just used two whole eggs and four servings of liquid egg whites.

You begin reading the article and the writer completely takes the conclusions out of context to freak you out.

After that, you throw all your egg white cartons away and start buying whole eggs in bulk.
You see where we are going with this?

This happens every day with false article headlines, misleading interpretations of the scientific data, and then consumers fret and go off and do extreme things.

This new study [1] is a perfect example of this.

Throughout the rest of this article, we will breakdown this new article that is claiming whole eggs are better than egg whites for muscle growth.

Don’t throw away your egg white cartons just yet ?


The Study and What the Hell is Muscle Protein Synthesis?

Let’s break down some key points here in the study we are going to be discussing.

  • 10 subjects (healthy young males)
  • They took all subjects through a decent resistance training program and immediately after gave them 18g of protein via whole eggs or 18g of protein via egg whites
  • The results showed that whole eggs stimulated muscle protein synthesis (MPS) acutely over liquid egg whites

Now, you’re probably like what the hell is muscle protein synthesis and what does it matter to me?
The best analogy we can give you is from Professor Stuart Phillips from McMaster University [2]:

“Imagine your muscle as a brick wall. When new bricks get delivered, these are the amino acids from proteins, on one end of the wall there’s a process to put bricks in which is muscle protein accretion and on the other end of the wall you take bricks out which is muscle protein breakdown. Protein synthesis is the bricks end of the wall and bricks out of the wall is protein breakdown and the net difference between the two are net muscle protein balance and this would be the rate at which your making things and subtracting at which the rate your breaking them down. If that’s in a positive direction the wall gets bigger (i.e., muscle growth), or if it’s in the negative direction, your muscle shrinks. Protein ingestion and resistance training is a potent stimulus to make the brick wall bigger and stronger (i.e., stimulate the protein synthetic process).”

We know that’s a lot to take in, but trust us when we say that analogy compared to the way textbooks break it down is a lot more digestible.

Now, let’s look at some of the study limitations

  • Only 10 subjects and all males. It would be interesting to see a larger sampling size and with women as well
  • This study investigated whole eggs vs egg whites in isolation. Very few if any people we know just eat in this fashion
  • This study looked at acute MPS (meal by meal). The effects of MPS for muscle growth need to be considered over time and long term (days, weeks, months) and that includes consumption of other foods throughout the day [3]

The total protein consumption in both conditions was only 18 grams, prior research shows you may need at least 20g of a high-quality protein to sufficiently maximize protein synthesis after resistance training [4] or even up 30-40g to stimulate MPS [5].

So, it’s not clear how results would change with a more usual consumption (i.e. double that amount) or if MPS was looked at over a longer term.


Practical Applications

Remember we said not to throw out your egg white cartons just yet?

The reason being this is an interesting study that suggests other nutrients besides protein may enhance anabolism.

That said, it’s important to point out that ultimately the effects of MPS for muscle growth need to be considered over time (days, weeks, months) and that includes consumption of other foods throughout the day (carbohydrates and fats).

While it’s possible that there are unique properties to whole eggs that maximize anabolism (i.e. lipids, micronutrients, antioxidant carotenoids, and microRNAs), it alternatively may well be that these properties are sufficiently available in other foods we normally eat (depending on one’s overall diet).

We’d also note, it’s always important to look at the context of a study when drawing evidence-based conclusions.

Instead of fretting over this new study, let’s wait until there’s more data conducted on it, and in the meantime, focus on these suggestions we have for you:

  • If you don’t have a cholesterol issue, then it’s okay to have whole eggs.
  • If you don’t prefer whole eggs (specifically the yolk), it’s fine to have liquid egg whites
  • If you think whole eggs aren’t nutritious, you are flat out wrong. Research shows the yolk is nutrient dense and may contain a variety of bioactive compounds (see above). The removal of the yolk and its associated nutrients from eggs may limit the stimulation of MPS rates as well as well as overall human health [6]
  • Instead of worrying about whole vs egg whites as protein sources for muscle growth, consider the hierarchy of importance for daily dietary protein [7]:
    • 1. Total Daily Protein Intake– what matters most is hitting your total protein goal at the end of the day (i.e., if your total target protein goal is 200g, then focus on hitting that number)
    • 2. Protein Distribution– it’s important to evenly distribute your protein at however many meals you eat per day (i.e., 150g per day and 4 meals per day, should be 50g per meal) this way it keeps your body in a muscle growth environment
    • 3. Protein Quality– include high quality protein sources (animal sources) such as: Eggs, chicken, milk, beef, fish, etc. to stimulate MPS due to the high leucine content
    • 4. Specific Protein Timing (pre/post workout or before bed)– Having enough protein pre and post workout for recovery is important for muscle growth and remodeling, as well as having high quality protein before bed to keep your body in an anabolic environment.

Now that you got some great info on whole eggs vs egg whites, keep in mind the hierarchy of importance for daily dietary protein intake is what matters most. Then go and enjoy that beautiful sizzling sound of when you have the frying pan on medium-high and you pour your eggs onto the pan and get your PROTEIN IN!
