Protein has always been important, but it's especially hot right now, and for good reason. It's not just an essential macronutrient, but also the building blocks for muscle strength, metabolism, and so much more. Talk to almost any expert, and they'll agree.
'Protein is an essential nutrient for so many bodily processes,' says Jessica Cording, RD, CDN, author of The Little Book of Game-Changers. 'It nurtures hair, skin, and nail health, builds and maintains tissues like muscles, supports connective tissue, and helps us feel full—and that's just scratching the surface.'
There are, however, a *lot* of opinions out there on how much protein you should be getting each day. Your favorite fitness influencer may tout one number while your health-minded best friend tells you something else. The truth is, everyone's needs are slightly different. And if you're super active, that influences your number too.

Generally, most people require about 25 to 30 grams of protein per meal. It's a good idea to spread it out throughout the day, too, says Keri Gans, RDN, author of The Small Change Diet. Most people tend to pack in the protein at dinnertime, but in reality, you can (and should) eat it all day long because your body doesn't store protein. It breaks the macronutrient down into amino acids, which are used to build and repair tissues or to be used as fuel, so you need to keep the protein intake coming.
Even knowing the general guideposts for protein intake, it can be hard to tell if it's the right number for you. You might find yourself wondering if you're hitting the gold standard on your protein intake or falling short.
Ahead, experts break down the major signs that you might need more of this macronutrient in your life.
Meet the experts: Jessica Cording, RD, CDN, is author of The Little Book of Game-Changers; Keri Gans, RDN, is author of The Small Change Diet; Gary Goldenberg, MD, is assistant clinical professor of dermatology at Icahn School of Medicine at Mount Sinai Hospital.
1) You're always hungry
Say you just ate a meal, but you feel like you need a snack already. Cording says this is one of the most common signs that you're not having enough protein. Protein helps you to feel full, and if you're not getting enough, you may end up hungry again pretty soon after you eat.
'If someone is constantly hungry, I'm always going to check to make sure they have enough protein,' Cording says.
2) Your cuts and scrapes take a while to heal
Protein is essential for wound-healing because it provides the basis for building new tissue and collagen, which are needed for your body's repair and growth, Cording explains. 'Sometimes when you don't eat enough protein, your body doesn't repair as well,' she says.
3) You're not building muscle
Yep, even if you're going hard on the weights, a diet that lacks protein means you won't really see much improvement in muscle mass. Of course, you won't build muscle by eating protein alone, but if you're running into this issue, Cording says to reassess your protein.
If you struggle to meet their daily protein needs within your regular meals, you can also opt for a protein powder to give yourself a little boost. Women's Health has quite a few favorites to recommend in that department.The Protein Playbook: Build Strength, Boost Metabolism, and Feel Energized

4) You're dealing with hair loss
Hair loss is actually pretty complicated, so it's hard to say that hair loss can automatically be chalked up to a lack of protein in your diet. But if you feel like there's no obvious reason for your hair loss, protein could be a culprit, according to Gary Goldenberg, MD, assistant clinical professor of dermatology at Icahn School of Medicine at Mount Sinai Hospital.
'Hair follicles are constantly cycling through growth (anagen), transition (catagen), and resting (telogen) phases,' he explains. 'Proteins are needed to support this constant turn over.' If you don't have enough protein, new healthy anagen follicles can't be produced—and you can end up losing hair, Dr. Goldenberg says.
Of course, upping your protein intake isn't always a magic solution. 'While in most [people] this process can be repaired by an increase in protein intake, in some patients it can become chronic and long term,' he says.
5) Your nails are brittle
Nails are mostly made of keratin, which is a form of protein. When there's not enough protein in your diet, you can't make and produce enough keratin, leading to brittle nails, Goldenberg says. Cue the dry and fragile nails.
Of course, calcium, vitamin C, biotin (vitamin B7), and vitamin E are key players here, too. So, you should try to incorporate foods such as nuts, vegetables, and eggs into your diet, to reap all the benefits of these key vitamins.
How To Get Enough Protein In Your Life
Trying to eat 25 to 30 grams of protein at every meal can feel a little overwhelming. That's why Cording recommends starting small if you suspect you're not having enough of the macronutrient right now. 'Increase it in an approachable way,' she says. 'That might mean having a slightly larger portion of Greek yogurt, adding cottage cheese to your scrambled eggs, or adding a scoop of collagen powder to your coffee. That can add up.'
Supplementing your diet with a protein powder shake can help. Gans recommends starting your day with protein to kick things off the right way. 'Don't skimp on protein at breakfast,' she says. 'Include good protein sources such eggs, cottage cheese, Greek yogurt, tofu, or smoked salmon."
Women's Health also has all kinds of protein-packed recipes for you to peruse. And remember, you can always ask your doctor or nutritionist (if you have one) what they recommend if you're stumped.
