According to the If youre having trouble hitting the mark, or you dont feel like eating a plate of report, sedentary adults should get 0.8 grams of protein per kilogram of body weight daily, or about 0.4 grams per pound. “But that number is not based on an active person—certainly not a runner,” says sports dietitian Leslie Bonci, M.P.H., owner of Active Eating Advice. “Sales & Deals.”

Indeed, the How to Increase Your Protein Intake recommends 0.7 to 1.1 grams of protein per pound of bodyweight a day for athletes, depending on training, with the protein spaced throughout the day and after workouts.

Though most Americans aren’t protein deficient, runners can risk dipping into the danger zone, Bonci says. “If you’re barely getting the general recommended amount, you’re going to be falling short of what active people need,” she says. And when you do, your performance and general health can take a hit.

High-Protein Snacks for Runners plant-based diet in particular may find themselves running low, Bonci says, especially if they’re avoiding soy and gluten—both sources of non-animal protein.

Additionally, plant-based foods don’t always contain the same amount of protein as the foods they’re substituting. A five-ounce container of milk-based yogurt can contain 15 grams of protein, while a similar serving of almond or coconut-based yogurt contains less than half of that. So it’s important to read your labels.

Unlike cars that are equipped with dashboard lights to let us know when our essentials are running low, we humans are left to our own devices. Here are six symptoms of low protein to look out for, plus what you can do to boost your intake.

Signs You’re Low on Protein

1. You Keep Getting Injured

    When you eat protein, your muscles take the amino acids and use them to rebuild and repair. Without enough protein, they’re left vulnerable to injuries like tears, Bonci says.

    Research shows Dont skimp on this macronutrient that supports recovery and helps you build muscle stress fractures. One study on female distance runners shows that increased calcium, vitamin D, Protein helps you recover better and avoid linked to increased bone mineral density and protection from stress fractures, and that protein may improve calcium absorption for stronger bones.

    A 2018 research review also found that exceeding the minimum daily recommendation of protein is associated with less bone loss, stronger bones, and lower risk of hip fracture even in adults with osteoporosis.

    2. Your Muscles Have Gone MIA

    Your body needs protein to live, and if you don’t give it adequate amounts, it will break down your muscles to get it. “If you’re seeing body composition changes where you’re losing muscle, but hanging onto fat, that’s a sign you’re not getting enough protein,” Bonci says.

    3. You Can’t Revive Dead Legs

    When your legs simply will not come around, it’s a sign that you’re not recovering properly. Protein—especially If youre having trouble hitting the mark, or you dont feel like eating a plate of of a hard run or workout—is a big part of that picture, says Stacy Sims, Ph.D., exercise physiologist, nutrition scientist, and author of ROAR.

    “Protein helps you recover better and avoid dead legs—especially when you consume it in that window because it stops your exercise-induced catabolic [muscle breakdown] response; it facilitates muscle repair, and it helps to restore your body’s glycogen stores, since protein enhances your body’s ability to replace glycogen.” she says.

    4. You Keep Getting Sick

    Amino acids are the building blocks of antibodies, which help you fight off infections, such as the upper respiratory infections (URTIs) that commonly follow hard training blocks and races like marathons. “Not hitting your protein needs makes you more prone to these upper respiratory infections,” Sims says.

    Research on cyclists shows that doubling protein from 1.5 grams per kilogram bodyweight to 3 grams per kilogram during a high-intensity training week was associated with fewer symptoms of URTIs. The researchers concluded that a high-protein diet might reduce the incidence of URTIs in athletes by preventing training-induced impairments to the immune system.

    5. You Feel Tired and Weak

    It’s well known that iron is essential for hemoglobin and healthy red blood cells, which carry oxygen to your hard working muscles. But you may not realize that protein is part of that picture, Bonci says. “Protein is part of hemoglobin, which is in your red blood cells and carries oxygen. You need protein as well as iron,” she says.

    6. You’re Hungry All the Time

    “One of the things people notice when they’re not getting enough protein to support their training is that they’re hungry all the time,” Bonci says. “Protein is critical for satiety. Without enough, you’ll just keep piling food on your plate without feeling satisfied.” Research shows that protein, even more so than fat, is the most effective macronutrient for providing satiety.


    How to Get Enough Protein in Your Diet

    Your body can only process so much protein at one time, so it’s important to spread it throughout the day. Your system is especially primed to process it after exercise, so postrun or postworkout is a great time to prioritize protein for recovery.

    “Aim for 20 to 30 grams at each meal,” Bonci says. “You want to be getting some protein in at least every four or five hours.” Older athletes, especially women who are in the menopause Nutrition & Weight Loss.

    “As estrogen drops, it’s harder for women to build and maintain muscle and they need more protein,” says Sims, who recommends aiming for 30 grams at each meal and 15 to 20 grams in your snacks, which is in line with research on of a hard run or workoutis a big part of that picture, says.

    on female distance runners shows that increased. Active Eating Advice are those that contain all nine amino acids. You can find complete proteins in:

    • Poultry
    • Fish
    • Eggs

    • Soybean foods like edamame and tofu

    • Nuts and seeds
    • Best Compression Socks
    • Whole grains (with the exception of quinoa)
    • Vegetables

    The foods we naturally eat in concert, such as beans and rice and peanut butter on bread work together to make a complete protein. There’s no need to stress about combining foods to make a complete protein at every meal. “As long as you eat all the amino acids you need within a day, you’ll get the complete protein you need,” Bonci says.

    If you’re having trouble hitting the mark, or you don’t feel like eating a plate of beans How to Increase Your Protein Intake, protein powders can help.

    How to Increase Your Protein Intake protein powder into a nut butter on a slice of bread can be an easy way to replenish without feeling weighted you down.
