Protein is an essential nutrient that is present in every cell of the body and is critical to supporting athletic training. Protein is responsible for building and maintaining muscles, and is what makes up the enzymes that power all reactions in your body that keep you going.2
Proteins are made of amino acids, which are building blocks that help grow and maintain the body’s tissues. Humans are not able to synthesize (or produce internally) certain amino acids, so they need to be consumed through food. The amino acids that need to come from dietary sources are called essential amino acids.1 This inability to produce essential amino acids is why the consumption of an adequate amount of high quality protein is vital for your health, epecially as athletes.
It is recommended that average adults get a minimum of 0.8 grams of protein per kilogram of body weight per day.3 Athletes, on the other hand, should consume higher amounts due to increased needs for muscle repair and training adaptations. The Academy of Nutrition and Dietetics recommends 1.2 to 2.0 grams of protein per kilogram of body weight per day for athletes, depending on training intensity.4 If you’re not consuming enough protein, your body may be giving you different signs that you need to eat more of it. Some signs that you can look for are decreased muscle growth or strength, getting sick more often, hunger, fatigue, unhealthy hair, skin, and nails, neurological disruptions, and swelling.
1. You can’t seem to build muscle
Do you feel like you’re not getting the results that you want? You may not be consuming enough protein for muscle growth. When you don’t get enough protein in your diet, your body will start to take it from other sources. Primarily, it will take protein from your muscles. This will cause muscle wasting and decreased strength.2 In order to provide the optimal amount of protein and amino acids to allow your muscles to recover and build, protein intake should be spaced throughout the day and after workouts.4
2. You’re getting sick more often
Are you getting sick more often than you have in the past? You could have a weakened immune system due to lack of protein in your diet. Protein is needed for the creation of antibodies, which are proteins that fight off diseases caused by pathogens that enter the body. Lack of protein can reduce the number of antibodies in your blood which can leave you defenseless to different pathogens.2
