The Customized Diet Panel: Using Genetic Nutrition Insights in Everyday Care

By Jen Milks, PhD, MBA
Biomedical Scientist & Educational Advisor

Your patients don’t want generic advice. They want to know exactly what works—for them.

And in a world where precision medicine is now the expectation—not the exception—nutrition is the most powerful place to start.

The ExtendingME Customized Diet Panel translates genetic data into real-world dietary strategies. By analyzing single nucleotide polymorphisms (SNPs) tied to how the body metabolizes carbohydrates, proteins, and fats, this panel helps clinicians guide targeted nutrition decisions—within the flow of everyday care.

This isn’t a specialty test reserved for complex cases. It’s a front-line tool for any patient who wants more energy, better body composition, metabolic balance, or a sustainable strategy for prevention and longevity.

From Guesswork to Strategy

How often do you hear:

  • “Should I go low-carb?”
  • “Why isn’t my ‘clean’ diet working?”
  • “How much protein do I actually need?”

These questions come up daily in primary care, functional medicine, wellness, and concierge settings. The Customized Diet Panel helps clinicians move from trial-and-error to targeted recommendations, backed by each patient’s biology.

No more guessing. No more cookie-cutter meal plans. Just data-driven direction.

Everyday Use Cases (Not Just the Outliers)

1. Weight Plateaus
For patients stuck despite tracking and effort, SNPs like:

  • FGF21 → May signal increased sugar or refined carb cravings, guiding swaps to low-glycemic alternatives.
  • PPARG, APOA2 → Suggest better outcomes on PUFA-rich diets vs saturated fat–heavy plans.

These aren’t radical overhauls—they’re minor but meaningful changes that move the needle.

2. Fatigue, Brain Fog, Cravings
These are the patients doing all the “right” things—clean eating, balanced plates—and still crashing by 3pm.

  • TCF7L2, MTNR1B → May signal impaired glycemic response to high-carb meals.
  • GCKR, PPP1R3B → Reveal protein load issues tied to glucose fluctuations.

The fix? Adjust meal timing, spread out protein, and pair carbs with movement.

3. Preventative and Annual Wellness Visits
Not everyone is in crisis. Many are just trying to stay ahead. The panel supports:

  • Cardiovascular health: Use fat metabolism SNPs to guide LDL-friendly swaps.
  • Brain longevity: Optimize omega-3 intake based on FADS variants.
  • Lean mass preservation: Structure protein distribution around genetic tolerance.

This turns routine visits into proactive, personalized care.

Easy to Use. Easy to Implement.

This test doesn’t add complexity. It reduces noise.

  • Reports are broken down by carbohydrates, proteins, and fats, with red/yellow/green indicators.
  • Actionable recommendations are grocery-list simple.
  • No genetic expertise required—just clinical insight.

It takes less than 10 minutes to review the report and start a conversation that actually sticks.

Driving Real Change Through Personalization

The right test isn’t one that tells you more, it’s one that tells you what to do next.

Instead of saying “eat better,” you can say:

  • “Your genes suggest sensitivity to saturated fats—let’s switch you to olive oil and walnuts instead of butter and coconut oil.”
  • “You’re a good responder to protein but spacing it across meals will serve you better than overloading dinner.”
  • “Let’s move your carbs earlier in the day—your SNPs suggest that’ll stabilize your energy.”

Patients engage when plans feel personal. Genetic insights create that moment of buy-in.

Supporting Everyday Choices

This panel doesn’t just help with diagnoses. It helps with decisions:

  • What to eat for breakfast
  • How to structure meals for satiety and energy
  • Why a certain food plan may finally make sense for that specific patient

It’s not about restriction. It’s about precision.

Clinical Takeaways

  • For everyday patients: Not just for GLP-1 or diabetes—use it for energy, prevention, and lifestyle optimization.
  • Fast and effective: Reports are easy to review, implement, and explain.
  • Drives adherence: Patients stick to plans they understand and believe in.
  • Replaces guesswork: SNPs reveal why certain diets succeed—or fail—for each individual.
  • Seamless integration: Ideal for primary care, wellness, executive health, and concierge medicine.


“Genetic insights aren’t just for rare diseases—they’re for everyday decisions.”

The ExtendingME Customized Diet Panel analyzes SNPs using RealTime PCR with the Illumina Global Screening Array. All testing is performed in a CLIA-certified laboratory and results are interpreted against peer-reviewed literature linking genetic variants to macronutrient metabolism, glucose regulation, lipid handling, and lifestyle-related health outcomes.
