Do you need to spend all that money on protein powder? Find out if you really need a protein shake before or after a workout to gain muscle!
Last week’s introduction to Savvy Sports Nutrition was a huge hit! In case you missed it, my first article in the Savvy Sports Nutrition series discussed what to eat before a post-work gym session. From the feedback I received, it seems that many of you are struggling with questions about what to eat around workout times and you don’t know where to turn for information. That’s why I’m really excited to educate on sports nutrition topics that come up in my counseling sessions or in conversations, and this week’s topic is so relevant because there is a ton of confusion regarding protein.
Before I answer the title question, here’s a little info about protein.
How much protein do you need?
I want to reiterate what I said in my first blog post, “These sports nutrition posts are for active people, like myself, who exercise frequently but don’t do it as a profession.” When I’m using numbers to describe the amount of something to eat, it’s very difficult to generalize for everyone.
- For the standard adult, the recommended daily allowance (RDA) of protein is 0.8g per kg of body weight.
- For the average gym goer/recreational athlete, the most protein needed is about 1- 1.2g per kg of body weight
I know this is rather complicated to understand. Basically, to figure out how much protein you need, divide your weight by 2. That’s around the amount that a normal gym-goer should have in a day. It’s not an exact science, but no one eats an exact number of grams of protein per day either… so, good enough!
What does protein do?
Protein is the building block of muscles and organs. It’s found in your muscles, skin, bones, hair, nails and basically every organ in your body.
Where does protein come from?
Protein is in many foods, but many people associate it with meat. Protein also comes from dairy, such as milk and yogurt, beans, nuts, and many whole grains.
When does an active individual need protein?
In general, carbohydrates are needed before a workout to give you energy and protein is needed after a workout to rebuild used muscles. Many people tell me that they have a protein shake in the morning and then go work-out. That’s not a great strategy because protein takes a long time to digest, so it sits in your stomach for an extended period of time. Yet, many people grab protein shakes because they are convenient, which leads me to my next (and title) point…
Do you need a protein shake?
I would much prefer that people eat food rather than supplements because no food serves just one purpose. In other words, if you have a glass of milk, you get protein, vitamins and minerals. Whereas, when you have a protein shake, you just get protein and artificial ingredients. To further express this point, let’s play a little game of “Eat This, Not That” using my handy chart (you know I love my charts).
|Eat This||Not That||Comments|
||Did you know that the whey in protein powder comes from milk? Yup, whey is the main protein in milk, so why not just drink the real thing?|
||Fruits have natural anti-inflammatory properties to fight post-workout inflammation. And a smoothie is just as easy to make as a protein shake!|
||Greek yogurt is one of the best sources of vegetarian protein. If you don’t like it on it’s own, add some honey or fruit. Or, use it as a substitute for sour cream in savory dishes.|
||Eating cholesterol is not associated with high blood cholesterol. Therefore, cholesterol is no longer a nutrient of concern, according to the new Dietary Guidelines. Eat your eggs!|
||You know what I’m going to say…
||Do you get the point that food has more benefits than supplements?|
I know this isn’t the answer that many of you want to hear, but you can definitely get sufficient protein (and many other nutrients) from food without drinking a protein shake. AND food has the added benefit of having many other nutrients in it, as well as protein. AND food is much cheaper to buy that protein powder! If convenience is what you are after, then make a smoothie with milk and yogurt. Your body will thank you for the extra vitamins and minerals!
Really? No one should drink protein shakes?
Of course there are always exceptions to the rule. I recently counseled a male, vegan, triathlete, who is 6’4”. He needs about 4,000 calories per day because of his activity level, and his diet consists of mostly vegetables, potatoes, rice, nuts and peanut butter. He drinks protein shakes, and I told him to continue to do so. Without the protein from those shakes, he would definitely become deficient and his body would be unable to recover from workouts. In extreme cases where meat, dairy, eggs or beans are not prevalent in the diet, protein shakes are appropriate.
