The Executive’s Protein Deficit: Why High Performers Are Quietly Losing Muscle Mass
Share
If you’re a CEO, founder, or high-performing professional, you’re probably not short on discipline.
You track revenue, manage teams, push through 12-hour days…
But there’s one metric almost every executive underestimates:
👉 Daily protein intake.
And it’s quietly costing you muscle mass, resilience, and long-term health.
In this post, we’ll break down why most high performers are in a chronic protein deficit, what that does to your physiology, and how to fix it with a simple, evidence-based strategy we use with executives at APEX Athletiq.
Your Body Can’t Store Protein – So It Steals It From Your Muscle
Here’s what makes protein unique compared to carbs and fats:
You can store unlimited fat in fat tissue.
You store carbohydrates as glycogen in your muscles and liver.
But amino acids (from protein) have no storage tank.
Your “reserve” is your muscle tissue.
That means when your protein intake drops below what your body needs—even for a day—your body will:
Break down muscle tissue
Strip it for amino acids
Use those amino acids to keep critical systems alive (immune function, enzymes, hormones, neurotransmitters)
For high-performing executives, this isn’t about looking good on the beach.
It’s about:
Stable energy across long workdays
Faster recovery from training and stress
Maintaining insulin sensitivity and metabolic health
Keeping strength, power, and balance as you age
As Dr Peter Attia puts it: there is almost no clinically relevant scenario where losing muscle mass is a good idea.
Yet most executives are slowly giving it away—through chronically low protein.
Why the RDA (0.8 g/kg) Fails High Performers
The current RDA for protein is 0.8 g per kg of body weight.
That number is:
Based on survival, not performance
Designed for an average, sedentary adult
Not built for people who train, travel, stress, and push hard
Isotope tracer studies (the gold standard in protein metabolism) suggest that:
👉 Most adults need at least 1.0–1.2 g/kg just to maintain muscle mass and avoid negative protein balance.
That’s 25–50% higher than the RDA.
Most executives who come to APEX Athletiq sit around 0.8–0.9 g/kg without realising it.
On paper, it looks “fine.”
In reality, it’s enough to:
-Maintain work stress
- Maintain belly fat
- Slowly lose muscle year after year
For a 180 lb (82 kg) executive:
-RDA target: ~65 g protein per day
- Realistic maintenance baseline: ~98 g per day
That 30–40 g gap is exactly where long-term muscle loss, frailty, and “normal aging” begin.
Anabolic Resistance: The Hidden Tax on Busy Leaders
As we age—and as life gets busier—our muscles become less responsive to protein.
This is called anabolic resistance.
It means:
- A 25-year-old may build muscle from 20–25 g of protein in a meal
- A 45–55-year-old executive may need 30–40 g in that same meal to get the same signal
But here’s the part most people miss:
Anabolic resistance is driven less by age and more by inactivity.
In one landmark study, researchers immobilised one leg of young adults while the other stayed active. The “casted” leg developed anabolic resistance. The active leg stayed completely normal.
Same person. Same age.
Different activity. Different muscle response.
That’s why at APEX Athletiq we focus on:
- Progressive strength training
- Higher protein intake
- Movement across the day
When older adults lift weights consistently, their muscle response to protein looks very similar to someone decades younger.
A 65-year-old CEO who trains properly can still build and retain muscle.
A 45-year-old founder who sits 10–12 hours a day and under-eats protein?
They’re aging themselves prematurely.
The Longevity ROI: What the Data Says About Higher Protein
When older adults increase their intake to around 1.2 g/kg per day, research shows:
- Age-related muscle loss is dramatically reduced
- Frailty risk drops by up to ~30% in older women
- Insulin sensitivity and metabolic health are better maintained
- Strength, balance, and resilience are preserved
This isn’t “biohacking.”
It’s baseline maintenance for a life where you:
- Still want to ski at 60
- Still want to deadlift at 70
- Still want to get off the floor and carry your own bags at 80
In other words:
Higher protein isn’t about looking shredded.
It’s about not becoming fragile.
The APEX Protein Protocol for Executives
At APEX Athletiq, we work with executives, founders, and high-performing parents who want both body composition and long-term health.
Here’s the protein framework we use inside our longevity-focused personal training:
1. Set a Clear Daily Target
A simple starting point:
1.2 g of protein per kilogram of body weight
Examples:
- 75 kg executive → ~90 g protein per day
- 90 kg executive → ~108 g protein per day
Most of our clients eventually feel better at 1.4–1.6 g/kg, especially when they’re training hard and leaning out—but 1.2 g/kg stops the slow leak.
2. Pair Protein with Strength Training
Protein without resistance training is like funding a building project with no builders.
To keep your muscles sensitive to protein:
- Train 2–4x per week with focused resistance training
- Prioritise compound lifts: squats, deadlifts, rows, presses, carries
- Progress load, volume, or density over time
This combination:
- Preserves and builds lean mass
- Improves insulin sensitivity
- Raises your “health floor” as you age
3. Distribute Protein Across the Day
Instead of one huge protein hit at dinner, aim for:
- 3–4 meals, each with 25–40 g protein
This improves muscle protein synthesis compared to:
- 10 g at breakfast
- 15 g at lunch
- 70 g at dinner
Same daily total, very different muscle outcome.
4. Choose High-Quality, Leucine-Rich Sources
To trigger muscle building, your body needs enough leucine, a key amino acid.
High-quality sources include:
- Lean red meat
- Poultry
- Eggs
- Fish and seafood
- Whey or high-quality protein powders
- Greek yoghurt, cottage cheese
Plant-based executives can still hit the target—but it usually requires:
- More planning
- Thoughtful combinations (e.g., tofu + tempeh + legumes)
-
Possibly a well-chosen protein supplement
How This Translates to Real Life for Executives
When busy high performers increase protein and train properly, they often report:
- More stable energy across the workday
- Reduced cravings and snacking
-
Easier fat loss (especially around the midsection
They’re not just lighter.
They’re stronger, more capable, and harder to kill.
The Bottom Line for High Performers
Because your body can’t store amino acids, there’s no buffer.
Miss your protein target, and your body will pull from your muscle to make up the difference.
Day by day, month by month, year by year—that’s how strong, capable executives turn into “normal” middle-aged adults who:
- Can’t sprint
- Can’t lift
- Can’t get off the floor without effort
For the high performer who cares about longevity, performance, and legacy, protein is not optional—it’s foundational.
The difference between 0.8 g/kg and 1.2 g/kg isn’t just a number.
It’s the gap between gradual decline and maintained vitality.
