Protein: Muscle-Building and Preventing Muscle-Loss

If you missed part 1 on protein needs and timing, go back and start there. In this post, I will discuss how to get that protein, the role protein plan in building muscle, and how protein prevents muscle loss.

Protein in Real Life

If the body can only use between 25-35 grams of protein at a time, that’s a number worth looking at. But what does 20-30 grams of protein mean when it comes to actual food?

 

 


  • 4 ounces of meat or seafood
  • 3-4 eggs
  • 1 1/2 cups of lentils
  • 1 cup of beans over 1 cup of brown rice or quinoa
  • 1-2 scoops protein powder (depending on the brand)
  • 1 cup of Greek yogurt

When you consider the recommendation of getting 20-30 grams of protein three times a day (minimum), it might not seem like it’s a high protein diet. However, it might be higher than your current diet.

It’s also important to consider the quality of your protein. The quality of protein is dependent on which amino acids (i.e. the building blocks) are present, and how easily your body can access those amino acids.

In general, animal proteins are considered complete (i.e. contain all amino acids the body needs) and tend to be higher quality. Plant-based proteins, on the other hand, are not considered complete, and are lacking one or more amino acid.

To ensure vegetarians and vegans get all the amino acids, similar to what is found in muscles, protein needs are higher. However, don’t get too caught up in the difference between animal and plant sources. The most important thing is that you’re choosing a variety of protein sources.

Protein as We Age

Around age 40, you start to gradually lose muscle and function – to the tune of about 1% of your muscle mass each year. Yikes! (This is really similar to osteoporosis and natural bone loss over time.)

Many people just accept this as part of life. They make adaptations in their lifestyle to get by with less muscle. But then life puts them to the test, and they realize there is a problem. For instance, one day you may find that you are unable to catch yourself as you lose your balance and fall.

You’ve probably heard the phrase “use it or lose it” when it comes to muscle. Yes and yes and yes. Just being on bedrest can cause a significant loss in muscle mass. Unfortunately, as you age, the likelihood and frequency of bedrest increases. You want to ensure that you are in good status before a health crisis hits you.

Preventing Muscle Loss

 

 


There is good news to this story. You can prevent and delay muscle loss through – you guessed it – exercise. Added bonus? The more muscle you have the better your metabolism is. Of course both the muscle and the metabolic benefits depend on you actually using the muscle. It’s not good enough to just take selfies of your biceps. You gotta use ’em. Strength training is important throughout life, but even more so as you age.

[Side note: remember that 1% loss per year after 40? That’s a big part of the decreased metabolism that you experience after 40.]

For those of you who are somewhat adverse to exercise, I want to challenge you to think about it differently. Maybe exercise has a horrible connotation for you. Maybe you associate it with weight loss and diets and obligation and misery.

What if – instead – you chose to infuse a new meaning to exercise – that it was your key to stress management and improved quality of life? What if “exercise” was about getting out there and enjoying the fact that your body still works?

Summary

Research tells us that there is about a 25% improvement in muscle building and muscle retention when you distribute protein over the course of the day, as compared to back-loading it at dinner. On a day-to-day basis, this might not feel huge. But over the long haul, it can really add up.

Consider adding a good source of protein to your breakfast, lunch, and snacks. Add some protein to your post-workout recovery. But don’t sweat the calculations, there is no need to obsess over protein.
