The Best Macronutrient Split for Your Body Type — Backed by DEXA Data

Trying to guess your ideal ratio of protein, carbs, and fats? You’re not alone.

Most people follow generic advice—like “40/30/30” or “high protein, low carb”—without knowing if it’s actually right for their body. But what if you could personalize your macronutrient split using real data about your body composition?

That’s exactly what a DEXA scan makes possible.

Why Your Body Type and Composition Matter

Your macronutrient needs aren’t just based on your weight. They depend on:

  • Lean body mass
  • Fat distribution (especially visceral fat)
  • Training goals (e.g., fat loss vs. performance)
  • Metabolic efficiency
  • Hormonal profile

A DEXA scan shows you precisely how much muscle and fat you’re carrying—and where. That gives you the insight to customize your macros in a way no scale, mirror, or online calculator can.

Common Goals & Suggested Macro Splits (Based on DEXA Data)

🔥 For Fat Loss (High Body Fat, Low Lean Mass)

  • Protein: 40–45%
  • Fats: 25–30%
  • Carbs: 25–30%

Why: Higher protein preserves muscle during a calorie deficit. Lower carbs help reduce insulin spikes and target visceral fat.

💪 For Muscle Gain (Low–Moderate Body Fat, High Lean Mass)

  • Protein: 30–35%
  • Carbs: 40–50%
  • Fats: 15–25%

Why: Ample carbs fuel training volume and recovery. Protein supports hypertrophy. Fats stay moderate to keep hormones balanced.

⚖️ For Recomposition (Moderate Body Fat, Low Visceral Fat)

  • Protein: 35%
  • Carbs: 30–35%
  • Fats: 30–35%

Why: A balanced approach supports building lean tissue while gradually trimming fat—especially effective if DEXA shows even body fat distribution and steady lean mass.

🧠 For Longevity & Hormonal Support (Postmenopausal or High Visceral Fat)

  • Protein: 30–35%
  • Fats: 35–40%
  • Carbs: 25–30%

Why: Higher fat supports hormonal stability. Moderate carbs and high protein help maintain bone and muscle mass, which DEXA scans often show are declining in these groups.

How to Use Your DEXA Scan to Adjust Your Macros

A monthly or bi-monthly DEXA scan lets you measure:

  • Lean mass gained or lost
  • Fat mass changes (especially in the abdomen)
  • Whether you’re losing fat and muscle (a sign you need more protein)
  • If carbs or fats are affecting your visceral fat trends

This allows you to fine-tune your macros for sustainable, measurable results.

Stop Guessing. Start Tracking.

If you’re not aligning your nutrition with your actual body composition, you’re leaving progress on the table. Generic macros don’t cut it—data-driven splits do.
