If you’ve spent any time on social media or in fitness circles lately, you’ve probably heard someone talking about protein. “Get more protein.” “Track your macros.” “You need at least 100 grams a day.”
But how much protein do you really need? And does that number change as you get older?
At Northern Touch CrossFit, we work with busy parents and professionals in midlife every day, and this is one of the most common questions we get. So let’s break it down in a way that’s actually useful—no PhD required.
Why Protein Matters (Especially in Midlife)
Before we talk numbers, let’s talk about why protein deserves your attention in the first place.
Protein isn’t just for bodybuilders or athletes. It’s essential for:
Building and Maintaining Muscle Starting around age 30, we naturally begin to lose muscle mass—a process called sarcopenia. Without intentional strength training and adequate protein, this loss accelerates. Muscle isn’t just about looking toned; it’s your metabolic engine. The more muscle you have, the more calories you burn at rest.
Supporting Recovery Every workout creates tiny tears in your muscle fibers. Protein helps repair and rebuild them stronger. Without enough protein, you’re not recovering properly, which means you’re not getting the full benefit of your training.
Keeping You Full and Satisfied Protein is the most satiating macronutrient. It keeps you feeling fuller longer, which helps prevent overeating and reduces cravings between meals. This is particularly helpful if weight loss is one of your goals.
Preserving Your Metabolism When you’re trying to lose weight, your body can break down muscle for energy if you’re not getting enough protein. Since muscle drives your metabolism, losing it makes further fat loss harder. Adequate protein helps you lose fat while maintaining muscle.
Supporting Overall Health Protein plays a role in immune function, hormone production, enzyme creation, and tissue repair. It’s literally the building block of your body.
The Standard Recommendation (And Why It’s Not Enough)
The standard recommendation you’ll see everywhere is 0.8 grams of protein per kilogram of body weight (or about 0.36 grams per pound).
For a 150-pound person, that’s only about 54 grams of protein per day.
Here’s the problem: this recommendation was designed to prevent deficiency, not to optimize health, support an active lifestyle, or maintain muscle mass as you age.
If you’re lifting weights, doing CrossFit, trying to lose fat, or over 40, you need significantly more protein than the bare minimum.
How Much Protein You Actually Need
The right amount of protein depends on several factors: your activity level, your goals, and your age. Here’s a more realistic breakdown:
For Active Adults (Strength Training 3-4+ Times Per Week)
Minimum: 0.8-1.0 grams of protein per pound of body weight
This is the sweet spot for most people who are training regularly and want to build or maintain muscle.
- 150-pound person: 120-150 grams of protein per day
- 180-pound person: 144-180 grams of protein per day
- 200-pound person: 160-200 grams of protein per day
For Adults Over 40 (Midlife and Beyond)
As we age, our bodies become less efficient at using protein to build and maintain muscle. Research shows that older adults need MORE protein, not less.
Recommended: 1.0-1.2 grams of protein per pound of body weight
This higher intake helps counteract age-related muscle loss and supports recovery.
- 150-pound person: 150-180 grams of protein per day
- 180-pound person: 180-216 grams of protein per day
For Weight Loss Goals
If you’re trying to lose fat while maintaining muscle (which you should be), protein becomes even more important.
Recommended: 1.0-1.2 grams of protein per pound of body weight
Higher protein intake during a calorie deficit helps preserve muscle mass, keeps you feeling full, and supports your metabolism.
For Less Active Individuals
If you’re not currently strength training or doing intense exercise, you can get away with slightly less, but you should still aim higher than the standard recommendation.
Recommended: 0.6-0.8 grams of protein per pound of body weight
That said, if you’re in midlife and not currently active, we’d strongly encourage you to start—and increase your protein accordingly.
What Does This Look Like in Real Food?
Numbers are great, but what does 120-150 grams of protein actually look like on your plate? Here are some examples:
High-Protein Foods and Their Protein Content:
- Chicken breast (4 oz): 35g protein
- Ground beef (4 oz, 90% lean): 28g protein
- Salmon (4 oz): 25g protein
- Greek yogurt (1 cup): 20g protein
- Eggs (2 large): 12g protein
- Cottage cheese (1 cup): 28g protein
- Protein powder (1 scoop): 20-30g protein
- Lentils (1 cup cooked): 18g protein
- Tofu (4 oz): 10g protein
- Almonds (1/4 cup): 8g protein
Sample Day Hitting 150g Protein:
Breakfast:
- 3 eggs scrambled (18g)
- 2 slices whole grain toast with almond butter (8g)
- Total: 26g
Snack:
- Greek yogurt with berries (20g)
- Total: 20g
Lunch:
- Grilled chicken salad with 6 oz chicken (52g)
- Mixed greens, vegetables, olive oil dressing
- Total: 52g
Snack:
- Protein shake (25g)
- Total: 25g

- Total: 39g
Daily Total: 162g protein
Common Mistakes People Make with Protein
Mistake #1: Front-Loading Protein at Dinner
Many people eat very little protein at breakfast and lunch, then have a huge piece of meat at dinner. Your body can only use about 30-40 grams of protein at once for muscle building, so spreading it throughout the day is more effective.
Fix: Aim for 25-40 grams of protein at each main meal.
Mistake #2: Not Counting Plant Proteins
If you eat beans, lentils, nuts, or whole grains, those contain protein too! While they may not be “complete” proteins on their own, they still count toward your daily total.
Fix: Track all your food to see your true protein intake.
Mistake #3: Thinking Protein Powder Is Cheating
There’s nothing wrong with using protein powder as a convenient way to hit your protein goals. It’s just food in a different form.
Fix: Use protein shakes strategically—after workouts, as snacks, or blended into smoothies.
Mistake #4: Forgetting to Adjust as You Age
The protein target that worked for you at 25 won’t cut it at 45 or 55. Your body needs more support as you age.
Fix: Reassess your protein intake every few years and adjust upward if needed.
“But Won’t Too Much Protein Damage My Kidneys?”
This is one of the most common concerns we hear, and we want to address it directly.
For healthy individuals with normal kidney function, there is no evidence that high protein intake causes kidney damage. This myth comes from recommendations for people who already have kidney disease, who do need to limit protein.
If you have healthy kidneys and no pre-existing kidney conditions, eating 1-1.2 grams of protein per pound of body weight is perfectly safe.
That said, if you have any kidney concerns or medical conditions, always consult with your doctor before making significant dietary changes.
Practical Tips for Getting Enough Protein
1. Start Your Day with Protein Don’t skip breakfast or have just coffee and a muffin. Start with eggs, Greek yogurt, or a protein shake to set yourself up for success.
2. Prep Protein in Bulk Grill several chicken breasts, hard-boil a dozen eggs, or cook a big batch of ground turkey on Sunday. Having protein ready to go makes hitting your target much easier during busy weeks.
3. Keep Protein Snacks Handy Stock your fridge and pantry with:
- Hard-boiled eggs
- Greek yogurt
- String cheese
- Protein bars
- Jerky
- Cottage cheese
4. Add Protein Powder Strategically Mix protein powder into:
- Smoothies
- Oatmeal
- Pancake batter
- Coffee (yes, really—try it!)
5. Think “Protein First” When you sit down to eat, eat your protein source first before filling up on other foods. This ensures you’re prioritizing what matters most.
6. Track for a Week You might be surprised by how little protein you’re actually eating. Use an app like MyFitnessPal to track your intake for one week. This awareness alone will help you make better choices.
The Bottom Line
For most active adults—especially those in midlife who are strength training regularly—you need significantly more protein than the standard recommendations suggest.
Aim for 0.8-1.2 grams of protein per pound of body weight, depending on your age, activity level, and goals.
Getting enough protein isn’t about perfection. It’s about consistency. You don’t need to hit your exact target every single day, but you should be in the ballpark most days.
At Northern Touch CrossFit, we know that nutrition can feel overwhelming, especially when you’re juggling work, family, and everything else life throws at you. But getting your protein right is one of the simplest, most effective things you can do to support your training, maintain muscle, and feel your best.
