Protein bar vs. shake: Which is better for you and your specific nutritional needs?
You start losing muscle at age 30 so meeting your protein needs becomes increasingly important.
In this article, we’ll delve into the pros and cons of protein bars versus shakes to determine which one is right for you!
Understanding the Importance of Protein
Protein is an essential nutrient that aids in muscle growth, repair, and maintenance.
Getting enough protein is important because it helps us grow muscles, and helps us heal faster after illness or injury.
A balanced diet includes sufficient protein and is key to optimal health and well-being.
Protein and Aging
As we age, our bodies undergo physiological changes, including a natural decline in muscle mass and strength.
Maintaining muscle mass is crucial as we age, as it directly impacts our mobility, metabolism, and overall quality of life.
Protein needs can vary based on a number of factors, however, below are general protein guidelines:
- Adults (19-64 years): 0.8 grams of protein per kilogram of body weight per day
- Adults (65+ years): 1.0 grams of protein per kilogram of body weight per day
Age-Related Muscle Loss
Sarcopenia is the progressive loss of muscle mass, strength, and function. It is a natural part of the aging process.
It is a major public health concern, as it can lead to disability, falls, and premature death.
A combination of the following factors contribute to sarcopenia:
- Decreased efficiency in building muscle
- Increased rate of muscle breakdown
- Reduced physical activity
Both protein bars and shakes can play a role in preventing age-related muscle loss/sarcopenia.
Protein can also improve your skin and prevent age-related skin issues. You can learn more in this Age-Defying Dietitian blog post – “How to Maximize Protein for Skin Health & Vitality“.
A protein bar is specifically formulated to be high in protein.
These nutrition bars are made with a variety of ingredients, such as protein powder, nuts, seeds, fruits, and vegetables.
The amount of protein in a protein bar can vary widely, from around 5 grams to over 30 grams per bar.
Protein bars provide a convenient way for people to supplement their daily protein intake, especially those who may have difficulty meeting their protein needs.
Pros of a Protein Bar vs. Shake
- Convenience: Protein bars can be carried anywhere and do not require refrigeration, making them more convenient than shakes.
- Nutrient-Dense: Bars contain added fiber and healthy fats, whereas shakes are mainly protein and liquid.
- Increased Satiety/Fullness: Protein bars typically contain more fiber than a shake, and therefore, will keep you feeling fuller longer.
- Lighter: Bars are lighter in weight, making them a good option for hikers and endurance athletes who carry their fuel.
Cons of a Protein Bar vs. Shake
- Added Ingredients: Bars may be high in sugar, saturated fat, and calories.
- Digestibility: May not be easy to digest, especially for individuals with a sensitive stomach.
- Cost: Bars tend to be more expensive and are time-consuming to make at home as compared to shakes.
Even though protein bars are more labor-intensive, you can easily make them at home. Check out this protein bar recipe from Tastes Better from Scratch!
Blending protein powder with a liquid (typically water or milk) creates a concentrated source of protein: the protein shake.
Athletes and fitness enthusiasts use protein shakes as a supplement, especially after workouts or when aiming to increase protein intake.
In addition, people use protein shakes for weight gain, weight loss, and recovery from illness.
Pros of a Protein Shake vs.Bar
- Rapid Absorption: Protein shakes are quickly absorbed, providing a fast infusion of protein to aid in muscle recovery and growth.
- Customization: Shakes can be tailored to specific nutritional and taste preferences.
- Lower in Sugar: Protein shakes tend to be lower in added ingredients, including sugar, as compared to bars.
- More Affordable: Shakes are more affordable than bars when prepared at home. Ready-to-drink shake options will be more expensive.
Cons of Protein Shakes vs. Bar
- Preparation Required: Protein shake preparation, including mixing the protein powder with a liquid of choice take time. This might not be as convenient as grabbing a pre-packaged protein bar.
- Less Satisfying: Some individuals may prefer to eat their calories rather than drink them, finding it more satisfying to consume whole foods.
- Heavy: Shakes are heavier than bars, making them a less appealing option for those who need to carry their fuel (hikers, endurance athletes).
