Introduction
Tracking macros is where most coaching begins. But when results stall when your client is doing everything right and still feels flat, inflamed, or exhausted—it’s time to ask: Is it really the calories? Or is it the cortisol? The testosterone? The microbiome? This article explores the three root-level performance disruptors you can’t ignore in 2025:
✅ Low testosterone
✅ Cortisol dysregulation
✅ Gut dysfunction …and how coaches using lab testing through 1st Optimal are solving these challenges faster, smarter, and more ethically without medical licensing.

Why the Macro-Only Model Falls Short
Yes—caloric balance matters. But body composition, performance, and energy depend on internal physiology, not just tracking apps. Research from JAMA Internal Medicine shows that individuals with untreated hormonal imbalances often don’t respond to nutrition and exercise protocols as expected, even in controlled studies. Macros are inputs. But hormones, gut health, and inflammation determine the output.
Testosterone: More Than Just Muscle
Testosterone influences:
- Energy and drive
- Recovery speed
- Fat oxidation
- Cognitive sharpness
- Libido and confidence
According to the Endocrine Society, testosterone levels drop 1–2% per year after age 30. That means by 40, many clients are already operating well below optimal ranges even if their labs are “normal.” Symptoms in men and women include:
- Poor sleep
- Low motivation
- Mood instability
- Loss of lean mass
- Reduced training capacity
The fix isn’t more caffeine. It’s clinical testing and evidence-based support something coaches can initiate through platforms like 1st Optimal.
The Stress Hormone Stealing Progress
Cortisol is essential. But when it’s out of balance?
❌ Belly fat increases
❌ Sleep gets disrupted
❌ Muscle breakdown accelerates
❌ Recovery slows
❌ Hunger signaling becomes chaotic Coaches working with high-performing adults (especially those juggling families, careers, and training) need to consider cortisol’s circadian rhythm. We test AM/PM cortisol alongside DHEA and melatonin to map adrenal health and support it through medical plans when needed.
The Gut-Hormone-Metabolism Connection
Gut health impacts:
- Nutrient absorption
- Hormone clearance
- Inflammation and immune load
- Mood and neurotransmitters
- Appetite regulation
Through GI-MAP testing, we identify:
- H. pylori
- Leaky gut (zonulin)
- LPS/endotoxin load
- Candida overgrowth
- Pancreatic enzyme deficiency
A 2019 Cell study linked poor gut diversity with fatigue, poor insulin response, and low testosterone. If you’re not testing the gut, you’re missing the dashboard behind your client’s metabolic engine.
How Labs Elevate Your Coaching Strategy
By testing:
- Free & total testosterone
- AM/PM cortisol curves
- GI-MAP markers
- Thyroid function (TSH, Free T3, T4)
- Insulin & A1C
…coaches can:
✅ Adjust protocols for real physiology
✅ Improve compliance through personalization
✅ Unlock performance plateaus
✅ Retain clients 2x longer by delivering deeper value
Real-World Case: From Stalled Progress to Surging Results
Client: Amanda, 38 | Online Fitness + Nutrition Client Coach: High-ticket transformation specialist
- Macros + strength training = no results
- Sleep disrupted, energy inconsistent
- GI-MAP → high zonulin, candida overgrowth
- Cortisol = elevated at night, flat in AM
- Testosterone = borderline low
- Interventions = GI protocol + sleep & adaptogen plan + medical TRT discussion
🧠 Within 90 days:
- 6 lb fat loss
- Improved compliance
- Renewed for 6-month coaching tier
- Reported “clear mind, consistent sleep, finally seeing scale move”

FAQs: Labs, Macros & Optimization
Q1. Can macros work on their own?
Yes—for some. But in midlife, 70% of clients need hormonal or gut support to see full results.
Q2. How soon can labs be integrated?
Week 1 onboarding is ideal. Clients get tested within days of signing up.
Q3. What if I don’t know how to interpret lab results?
Our team provides summaries and optional consults to make integration easy.
Q4. Is this compliant?
Yes. All testing and medical recommendations are managed by licensed U.S. providers.
Q5. Will my clients think I’m trying to upsell them?
No. They’ll view this as next-level personalization and trust you more because of it.
Conclusion: It’s Time to Move Beyond Macros
If you’re still building your entire coaching offer on calorie tracking and motivation, you’re leaving results and retention on the table. Your high-performing clients aren’t just hungry for transformation. They’re ready for precision. They want to know: “What’s going on inside me?” And when you can give them that answer—you win their trust, loyalty, and long-term business. Let’s upgrade what coaching means in 2025. Together.
