Protein seems to be everywhere right now. High-protein recipes, protein-packed snacks, shakes, powders—and constant reminders to “hit your protein.”
But does protein really matter that much? And how much do you actually need?
For this month’s Ask a Trainer, we’re breaking down why protein is important, especially if you’re strength training, and how to figure out an appropriate amount for you.
Does Protein Really Matter?
Yes—but you don’t need to make it complicated.
Protein is one of the three macronutrients, along with carbohydrates and fats. It plays an important role throughout the body, including helping build and repair muscle tissue.
When you strength train, you’re giving your body a reason to adapt and become stronger. Consuming enough protein provides your body with the amino acids it needs to support that repair and muscle-building process.
Protein can also help with satiety, making meals more satisfying, and can be especially important when your goal is fat loss because adequate protein—combined with resistance training—can help you maintain lean muscle while losing weight.
How Much Protein Do You Actually Need?
There isn’t one perfect number for everyone. Your protein needs can vary depending on your body size, age, activity level, training routine, overall calorie intake, and goals.
For active adults who are regularly strength training, a useful general target is approximately 1.6–2.2 grams of protein per kilogram of body weight per day, or roughly 0.7–1.0 gram per pound of body weight.
For example, someone who weighs 150 pounds might aim for approximately 105–150 grams of protein per day.
That doesn’t mean you need to hit an exact number every single day. Think of protein as a target range rather than a pass-or-fail goal. Consistency over time matters more than whether you hit the perfect number on Tuesday.
Do You Need Protein Immediately After a Workout?
You’ve probably heard about the “anabolic window”—the idea that you have to drink a protein shake within 30 minutes of finishing your workout or you’ll miss your opportunity to build muscle.
Fortunately, it’s not that dramatic.
Your overall protein intake throughout the day is more important than racing to get a shake the second your workout ends. Having a meal or snack containing protein within a few hours around your training session is generally a practical approach.
What Are Good Sources of Protein?
Protein doesn’t have to come from shakes or bars. Whole-food sources can include chicken, turkey, fish, lean beef, eggs, Greek yogurt, cottage cheese, tofu, tempeh, beans, lentils, and other protein-rich foods.
Protein powders can be convenient, especially when you’re busy, but they’re a tool—not a requirement.
One simple strategy is to include a meaningful source of protein at each meal rather than trying to squeeze most of your daily protein into dinner.
Protein Helps—but It Isn’t the Whole Picture
Eating more protein by itself won’t automatically build muscle.
Your body still needs a reason to build and maintain that muscle, and that’s where progressive strength training comes in.
Protein, strength training, adequate calories, carbohydrates, healthy fats, sleep, and recovery all work together. There isn’t one food, supplement, or macronutrient that replaces the fundamentals.
The PFLA Takeaway
If you’re working hard in the gym but aren’t paying attention to protein, it may be worth taking a closer look at your daily intake. You don’t have to obsessively track every gram—start by making protein a priority at each meal and build from there.
