Why Most Men Undereat Protein (And Why It Matters More Than You Think)

September 28, 2026MissionFit Team4 min read

Protein isn't just for bodybuilders—it’s crucial for staying strong, lean, and resilient as you age. Here’s why you’re probably not getting enough.

Why Most Men Undereat Protein (And Why It Matters More Than You Think)

I’ll never forget the time a buddy at the gym—huge guy, solid bench, looked the part—told me, “Yeah, I get plenty of protein. At least two eggs with breakfast!” I actually laughed out loud. Not to be rude, but that’s about 12 grams of protein. And if you’re aiming to stay strong, lean, and healthy as you get older, that’s not gonna cut it.

But here’s the thing. Most guys (even dedicated lifters) routinely undereat protein. We think because we have chicken at lunch or throw some beef on the grill a few nights a week, we’re all set. Truth is, unless you’re tracking—and I mean really tracking—protein, you’re probably falling short. And this matters more than you think, especially if you want to age well, keep muscle, and avoid that dreaded ‘skinny fat’ look that sneaks up on you after 35.

What Does Enough Protein Even Look Like?

Let’s clear the air. The old government recommendations (0.8g per kg of bodyweight) are the absolute bare minimum to avoid deficiency, not to thrive. Research keeps confirming that active men, especially those who want to keep or build muscle, need much more. The sweet spot? Somewhere between 0.7–1 gram per pound of lean body mass. For most guys, that’s at least 120–180 grams a day. Not a typo.

Here’s a quick exercise:

  • Next time you eat, track your protein—just that one nutrient. Add it up at the end of the day. Surprised?

I sure was, the first time I did it. I’d been “eating well” for years, but I was barely scraping 90 grams. I was leaving muscle (and recovery, and satiety) on the table.

Aging is inevitable. Decline is optional.

Why Protein Matters More as You Age

When we’re young, we can get away with a lot—pizza runs, skipping meals, random sleep. But as you move past 30, your body starts to change. Muscle loss (sarcopenia) becomes a real threat. And no, it’s not just a problem for frail old folks. Even active guys start losing a percent or two per year unless they actively fight it. Want to know the best weapon? Consistent, adequate protein intake.

It’s not just about looking good shirtless (though let’s be honest, that doesn’t hurt). Muscle is metabolically active—meaning it burns calories even at rest. It protects your joints, supports balance, and even helps regulate blood sugar. John Piper once said, “God is not glorified in our being strong in ourselves.” True. But taking care of our bodies—these tents God’s given us (2 Corinthians 5:1)—is part of stewarding the gifts He’s entrusted to us.

“Truth is, unless you’re tracking—and I mean really tracking—protein, you’re probably falling short.”

What Happens When You Don’t Get Enough?

  • Harder to build (or keep) muscle: Even if you lift, low protein slows your gains to a crawl.
  • Slower recovery: Soreness lingers. Workouts feel harder. You start skipping leg day (don’t lie).
  • Weaker immune system: Protein is literally the building block of your defenses.
  • Easier to gain fat: Without enough protein, your body scavenges muscle during calorie deficits—which means you lose muscle before you lose fat.

And maybe most importantly: You just feel less resilient. More creaky, more tired, less ready to tackle what God’s put before you.

How to Actually Hit Your Protein Goals

Let me guess: You’re not interested in eating dry chicken breast six times a day. Me neither. But hitting protein doesn’t have to be boring or complicated. Here’s what works for me and my clients:

  • Front-load your day: Start with 30–40g at breakfast (Greek yogurt + protein powder = quick win).
  • Double up at lunch and dinner: Most guys need at least 6–8oz of lean meat per meal. Think steak, chicken, salmon, eggs, even tofu or tempeh if you’re plant-based.
  • Snack smart: Instead of chips or pretzels, reach for beef jerky, cottage cheese, or a protein shake.
  • Use a quality supplement: There are days when you just can’t hit your numbers with whole foods—no shame in shaking up a scoop or two of MissionFit REBUILD (it’s loaded, and it doesn’t taste like chalk).

Faithful Stewardship Means Attention to the Small Things

Here’s the bottom line—neglecting protein seems like a small thing. But it adds up over decades. Charles Spurgeon put it like this: “It is not how much we have, but how much we enjoy, that makes happiness.” I’d tweak that a bit: it’s not just what you eat, but how consistently and intentionally you nourish the body God gave you.

So next time you sit down to eat, ask yourself—am I fueling for the calling God’s put on my life? Or am I winging it and hoping for the best?

You only get one body. Feed it wisely. Train hard. And remember, a little intentionality today means a lot less regret tomorrow.


“Therefore, whether you eat or drink, or whatever you do, do all to the glory of God.” (1 Corinthians 10:31, NKJV)
