MCTs: The Secret Weapon for Quick, Clean Energy

The Smart Fat for Performance

In endurance fueling, not all fats are created equal.
Medium-Chain Triglycerides (MCTs) stand out as a high-performance fuel: quick to absorb, clean to burn, and ideal for athletes who train long and hard without relying on sugar.

If you're pursuing fat adaptation, metabolic flexibility, or simply want faster, smoother energy, MCTs are your ally.

What Are MCTs?

MCTs are a category of dietary fat made up of medium-length carbon chains (typically 6–12 carbon atoms).
Their structure makes them unique:

  • Easier to digest than long-chain triglycerides (LCTs)

  • Bypass the lymphatic system → go straight to the liver

  • Quickly converted into ketones, a clean-burning fuel for both the brain and body

This makes MCTs more than just “another fat” — they’re a fast-track energy source.


Types of MCTs and Their Role

  • C8 (Caprylic Acid):

    • Fastest MCT for ketone production

    • Minimal processing needed → ideal for instant mental and physical energy

  • C10 (Capric Acid):

    • Also rapidly absorbed and supports ketogenesis

    • Often used alongside C8 for balanced performance

  • C12 (Lauric Acid):

    • Technically on the edge of MCT classification

    • Slower to convert, but still supports immunity and satiety

Most endurance-oriented MCT products prioritize C8 and C10 for performance, which is what Holyfat focuses on.


Why MCTs Matter for Endurance Athletes

  1. Fast Absorption
    MCTs don’t require bile salts or micelle formation for digestion — making them available for energy faster than typical fats.

  2. No Insulin Spike
    They offer clean fuel without affecting blood sugar or insulin — critical for fat-adapted or low-carb athletes.

  3. Supports Ketone Production
    Especially C8 — elevates ketone levels to power brain and muscle with metabolic efficiency.

  4. Reduces GI Distress
    Many endurance athletes struggle with gut issues from sugar-heavy fuels. MCTs offer fuel without fermentable carbs.

  5. Backs up Glycogen
    MCTs help preserve glycogen stores — important for long races where every bit of energy counts.

When to Use MCTs for Best Results

  • Pre-Workout: Take 15–30 minutes before training for fast-access fuel

  • During Long Sessions: Use as an intra-session fuel to support fat oxidation and maintain mental clarity

  • Fasted Training Support: Prevent bonking while staying in a low-insulin, fat-burning state

  • Recovery: Aid metabolic recovery and curb post-session hunger without sugar


How Holyfat Optimizes MCTs for Performance

At Holyfat, we don't just add fat — we use specific MCTs (C8 & C10) to:

  • Deliver quick energy when you need it most

  • Enhance metabolic efficiency and ketone production

  • Avoid the gut-bomb effect of heavy oils or sugary gels

Each Holyfat product is built to support fat-adapted athletes from start to finish — whether you're doing a 6-hour trail run or training metabolic flexibility through low-carb sessions.


MCTs vs. Carbs: Why MCTs Win in the Long Game

Feature Carbs (Gels) MCTs (Holyfat)
Absorption Speed Fast Fast
Blood Sugar Impact High spike/crash Stable
GI Risk Moderate to high Very low
Energy Duration Short (~30–45 min) Long (~90+ min)
Metabolic Support None Enhances fat burn/ketones
