As a registered dietitian, I always advise clients to focus on food first and supplements second. Protein shakes, however, play a unique role for athletes, the elderly, and many people recovering from surgery or an illness. For these individuals, protein shakes are one of the most practical ways for them to meet their individual protein, calorie, or essential micronutrient requirements.
Protein shakes are designed to provide the 9 essential amino acids that are required for building and maintaining protein. They are usually rich in the most important aminos for muscle-building, which include leucine, isoleucine, and valine. Decades worth of studies reveal that high-quality protein helps build and maintain muscle, control appetite, increase metabolism.
While you can plan meals and snacks that provide similar macronutrient profile that protein shakes provide, doing so will require a lot of time and expertise compared to the convenience of buying a ready-to-drink protein shake online or at your local food retailer. Protein shakes are usually also fortified with essential micronutrients, including B-vitamins, antioxidants, vitamins A and D, and many other nutrients that are often under consumed.
That said, the healthiest diets are those that are primarily plant-based and include a wide variety of natural, whole foods. Ready-to-drink protein shakes should be enjoyed as a complement to a wholesome eating plan, not to make up for a poor diet.
How Much Protein Do You Need?
The recommended daily intake of protein for sedentary consumers is a minimum of 0.8 grams of protein per kilogram of body weight, or 0.36 grams per pound. However, most experts recommend well over these numbers to optimize protein intake to help build and maintain lean body mass and for improved health and well-being. For those who are moderately active, a good goal is 1.3 grams of protein per kilogram body weight.
According to the International Society of Sports Nutrition, active individuals should strive for 1.4 to 2.0 grams of protein per kilogram of body weight or 0.6 to 1 gram per pound. A study published in the International Journal of Sports Nutrition and Exercise Metabolism reported that for athletes attempting to lose body fat, protein recommendations are 1.6-2.4 grams per kilogram of body weight or 0.7 to 1.1 grams per pound.
Lastly, protein shakes are often enjoyed as a meal replacement if you're traveling or are on a tight deadline and can't stop working to eat a balanced meal. However, it is noted that chronic intake of protein greater than 2 grams per kilogram body weight may cause GI or renal and vascular abnormalities, so there is still such thing as too much protein.
If you're older, protein shakes are also an easy way to get high-quality protein and other essential nutrients in your diet, at a time when it's likely that you aren't getting enough protein or essential amino acids, and your daily calorie intake may be low. At the same time, for those trying to lose body fat and improve their lean muscle mass, protein shakes can play an essential role in maintaining lean tissue while you shed fat mass. A general goal of 20 to 30 grams of protein per main meal is a good rule of thumb for most individuals.
A protein shake can is a convenient way to get a high-quality dose of 15 to 30 grams of protein per ready-to-drink bottle. And, since it's fortified, it's like taking high-quality protein with a multivitamin. There are dozens of ready-to-drink protein shakes available at your local supermarket, ranging from milk-based to plant-based options. The dairy-based shakes are rich in whey, casein, or a combination of both, while plant-based shakes are often made with soy milk, almond milk, or pea protein.
Keep these guidelines in mind when choosing a healthier ready-to-drink protein shake:
- Calories: Choose protein shakes that have up to 250 calories. If you are trying to lose body fat, stick with protein shakes with lower calorie counts and fewer carbohydrates.
- Protein: A protein shake should have 15-30 grams of protein per bottle. More than 30 grams of protein in a single eating occasion provides no additional benefits.
- Carbs: Unless you're an athlete looking for protein shakes as a recovery aid, look for shakes that keep added sugars to less than 10 grams.
- Plant-based: For plant-based protein shake, look for those made with more complete proteins like soy or pea protein.
