Whether you’re a workout class connoisseur, triathlete, or bodybuilder, you know protein is critical for making major fitness gains.
“Protein is vital for the body,” says Jonathan Valdez, R.D., owner of Genki Nutrition. “Not only does it provide the building blocks of muscle, hair, and skin, but it’s also essential for making enzymes, hormones like insulin, and antibodies for your immune system.”
However, the types of protein you eat, when you eat them, and how much you eat all influence the benefits you reap. If you’re prepping extra chicken breasts on Sundays or carrying single-serving packets of protein powder everywhere you go, here’s how to get the most bang for every bite (or sip).
How Much Protein You Need
While the government’s recommended daily value for protein is just 0.8 grams per kilogram of body weight (that’s 51 grams a day for a 140-pound person), many experts recommend eating more—especially if you’re active.
Georgia Rounder, R.D., recommends frequent exercisers eat anywhere from 1.2 to two grams of protein per kilogram of body weight per day. (That’s between 75 and 126 grams a day for that same 140-pound person.)
Here’s a little perspective: recent research suggests most Americans already meet or exceed the basic protein recommendation. So if you’re eating a reasonably balanced diet, you’re probably not deficient. The real question isn’t “Am I getting enough?” but rather “Am I getting the right amount for my goals?”
Why Active People Need More
Here’s the thing: when you exercise, you’re essentially creating tiny tears in your muscle fibers. That sounds scary, but it’s actually a good thing—it’s how muscles grow back stronger. Your body needs protein to patch up those tears and build new muscle tissue. The more you work out, the more repair work your body has to do.
Think of it this way:
- Light activity (walking, gentle yoga): The standard 0.8g/kg might be enough
- Moderate exercise (gym sessions 3-4 times a week): Aim for 1.2-1.4g/kg
- Intense training (daily workouts, endurance sports, heavy lifting): You’ll want closer to 1.6-2.0g/kg
What Does That Actually Look Like?
Let’s make those numbers a bit more real. If you weigh 165 pounds (75 kg) and hit the gym regularly, you’re looking at roughly 90 to 120 grams of protein per day. That might sound like a lot, but it breaks down pretty easily:
- A chicken breast at lunch: ~30g
- Greek yogurt for a snack: ~15g
- Salmon at dinner: ~25g
- Eggs at breakfast: ~12g (two eggs)
- A protein shake after your workout: ~20-25g
See? You’re already most of the way there without thinking too hard about it.
Protein Needs Change With Age
Here’s something worth knowing: your protein needs actually increase as you get older. Research suggests that adults over 50 may benefit from more than the standard recommendation—often somewhere around 1.2 to 1.6 grams per kilogram daily—to maintain muscle mass and strength.
Why? As we age, our muscles become a bit less efficient at using the protein we eat. Scientists call this “anabolic resistance,” but really it just means older muscles need a bigger protein signal to kick into gear. Studies suggest that while a 25-year-old might need about 20 to 30 grams of protein to maximize muscle building after a meal, someone over 50 might need closer to 30 to 40 grams to get a similar response.
This isn’t something to stress about—it’s just good to know. Your body is still perfectly capable of building and maintaining muscle; it just needs a little extra fuel to get there.
The good news? Meeting these higher needs doesn’t have to be complicated. It might just mean:
- Adding an extra egg to your breakfast
- Choosing Greek yogurt over regular
- Including a protein shake as an afternoon snack
- Bumping up your portion of chicken or fish at dinner by an ounce or two
The Muscle Loss Reality
Here’s something that might surprise you: muscle loss actually starts in your 30s or 40s—not your 60s like many people assume. After about 50, you can lose roughly 1% to 2% of your muscle mass per year if you’re not actively working to maintain it. That’s why combining adequate protein with some form of strength training becomes especially important as the years go by.
What Types Of Protein To Eat
All sorts of foods out there provide protein, but they’re not all quite the same. Every protein source contains amino acids (compounds that make up protein and perform other functions in the body), but different proteins contain different types of amino acids, and in different amounts.
Animal foods, like eggs, milk, Greek yogurt, chicken, and fish, are often described as ‘high-quality’ or ‘complete’ proteins because they contain all nine essential amino acids (the aminos our body cannot manufacture itself).
Certain plant foods, like soy, buckwheat, and quinoa, also provide all of these essential amino acids, but most plant-based proteins are limited in one or more and are known as ‘incomplete’ proteins.
Complete vs. Incomplete: What It Really Means
While complete proteins may pack an especially potent punch of amino acids in every serving, that doesn’t mean you have to eat them. In fact, research shows you don’t need to consume all of the essential amino acids in every single meal, as long as you’re eating a variety of protein sources daily. (Great news for vegans!)
Your body is pretty clever—it keeps a temporary “pool” of amino acids that it can draw from throughout the day. So if your lunch is missing a certain amino acid, your body can grab it from the pool and fill in the gaps. The key is variety over time, not perfection at every meal.
Making Incomplete Proteins Work Together
With a little strategy, even a completely plant-based meal can check off all of your essential amino acid boxes. Pair certain incomplete proteins together, and the final product can pack all of the essential aminos you need. (Incomplete proteins that fill out each other’s missing aminos are known as ‘complementary’ proteins.)
“Some examples of complementary protein pairs include grains with legumes and grains with nuts or seeds,” says Rounder.
That might look like:
- A few tablespoons of hummus slathered on pita bread
- Almond butter on whole-grain toast
- Rice and black beans (a classic combo!)
- Lentil soup with a crusty roll
- Trail mix with nuts and seeds
And remember—you don’t even need to eat these combinations at the same meal. As long as you’re getting a variety throughout the day, your body will sort out the rest.
Understanding Your Protein Powder Options
Protein powders can also help you reach your daily protein needs, but they, too, are subject to the complete-incomplete situation that affects whole-food proteins.
Here’s a quick breakdown:
Complete protein powders:
- Dairy-based options (whey, casein) contain all essential amino acids
- Most plant proteins made from a blend of sources (like pea + rice together)
Incomplete protein powders:
- Collagen—great for skin and joints, but missing some essential aminos
- Single-source plant powders like pea, hemp, or rice on their own
When shopping for protein powders, quality matters. Look for products that have been third-party tested for purity and potency—this helps ensure you’re getting what the label promises without any unwanted extras.
Why Whey Is So Popular
Ever wonder why whey protein is such a go-to for gym-goers? Beyond being a complete protein, whey is particularly high in leucine—an amino acid that’s especially good at triggering muscle protein synthesis. It also digests quickly, making it a convenient option when you want something easy to absorb.
That said, plant-based blends have come a long way. Many now combine pea, rice, and other sources to create a more complete amino acid profile. If dairy doesn’t agree with you or you prefer plant-based options, you’ve got plenty of solid choices.

Protein powders are super-convenient and helpful; just don’t let them replace whole-food proteins, which also offer a variety of other nutrients, says Valdez. Think of powders as a supplement to your diet, not a substitute for real food.
When To Eat Protein
Most Americans eat little-to-no protein with breakfast, some at lunch, and a ton at dinner. (Sound familiar? You’re not alone—research shows the average American gets about 13 grams at breakfast and nearly 40 grams at dinner.)
The issue with that: According to one study published in the Journal of Nutrition, protein consumption skewed toward the evening could contribute to potential less-than-optimal muscle growth. By eating this way, we deprive our body of the building blocks it needs for muscle-building all day, and then overload it come nightfall.
Here’s what’s really interesting: research from the University of Texas found that spreading protein more evenly across meals (think ~30 grams at breakfast, ~30 at lunch, ~30 at dinner) resulted in about 25% higher 24-hour muscle protein synthesis compared to the typical pattern of saving most protein for dinner—even when the total daily protein was exactly the same.
The body can only utilize so much protein to repair muscle, build hormones, and fulfill other needs at a time, so (just like any other macronutrient) excess is stored as fat.
Spreading It Out: A Simple Strategy
To correct this, make sure every single meal and snack you consume contains some protein, says Rounder. Aim for up to 25 to 30 grams in meals, and at least seven to 12 grams in snacks.
That could look like:
- Breakfast: Scrambled eggs with avocado and wheat toast
- Lunch: A salad loaded with leafy greens and four ounces of salmon
- Snack: A quarter-cup of almonds or a large hard-boiled egg
- Dinner: Grilled chicken with roasted vegetables and quinoa

Easy Breakfast Protein Swaps
Breakfast tends to be where most people fall short. Here are some simple ways to boost your morning protein without a complete overhaul:
- Swap regular oatmeal for oatmeal mixed with protein powder or Greek yogurt
- Add cottage cheese to your morning toast instead of just butter
- Toss a handful of nuts into your smoothie
- Make a quick egg muffin batch on Sundays for grab-and-go mornings
The Post-Workout Window: More Flexible Than You Think
If your snack-time falls after a workout, up the protein to about 20 grams to support muscle recovery, Rounder adds. Try two hard-boiled eggs and a small handful of cashews, four ounces of tuna on Ezekiel toast, or a protein bar.
You might have heard about the “30-minute anabolic window”—that supposedly magic timeframe when you must eat protein right after your workout or miss out on gains. Good news: recent research suggests this window is actually much wider than previously thought, extending for a few hours post-exercise (and often depending on what you ate before training).
In fact, research suggests the “anabolic window” is way less dramatic than people make it out to be—think hours, not minutes. What matters most is total daily protein, and then making sure you get a solid serving sometime before and/or after training (especially if you trained on an empty tank).
So if you can’t stomach a protein shake immediately after hitting the gym, don’t stress. As long as you’re getting adequate protein throughout the day, you’ll still see results.
The Pre-Sleep Protein Trick
Here’s something that might surprise you: eating protein before bed can actually help your muscles recover overnight. Studies show that consuming about 20 to 40 grams of slow-digesting protein (like casein) before sleep may increase overnight muscle protein synthesis—especially when it fits your overall daily calories and routine.
This makes sense when you think about it. You’re fasting for seven to eight hours while you sleep, and your muscles are still working to repair themselves. Giving them some fuel before bed keeps the recovery process humming along.
A pre-sleep protein snack might look like:
- A cup of cottage cheese with a drizzle of honey
- A casein protein shake
- Greek yogurt with a handful of berries
Debunking the “30-Gram Myth”
You may have heard that your body can only absorb 20-30 grams of protein at a time, and anything above that just goes to waste. The truth? That’s not quite accurate.
Your body can actually absorb much more protein than that—it just uses it at different rates for different purposes. While there is an upper limit to how much protein can be used for muscle-building in one sitting (around 0.4 grams per kilogram of body weight, or roughly 25-40 grams for most people), the rest doesn’t disappear. It gets used for other important functions or stored for later.
Here’s another way to think about it: if you eat a big steak with 50 grams of protein, your body isn’t going to waste half of it. It just won’t all go toward building muscle in that moment. Some will be used for energy, some for making enzymes and hormones, and some stored for future use.
The real takeaway isn’t about avoiding “too much” protein at once—it’s about not putting all your eggs in one basket (pun intended). Spreading your intake across the day gives your muscles multiple opportunities to build and repair.
Putting It All Together
The “right way” to consume protein isn’t about following rigid rules—it’s about being a little more intentional with how you eat throughout the day. Here’s a quick checklist:
- Aim for 25-30 grams of protein at each main meal
- Include 7-12 grams of protein in your snacks
- Mix up your protein sources (animal, plant, or both!)
- Don’t stress about perfect post-workout timing
- Consider a protein-rich snack before bed if muscle recovery is a priority
Your Personal Protein Game Plan
If you’re feeling overwhelmed, start simple. Pick one thing from this article that feels doable—maybe it’s adding more protein to breakfast, or swapping your afternoon chips for a handful of almonds and some cheese. Small changes add up.
And remember: the “best” protein strategy is the one you’ll actually stick with. Whether you’re 25 or 65, a dedicated athlete or a casual gym-goer, these strategies can help you get more out of every gram of protein you eat. And that’s something we can all feel good about.
