Carbs and Energy: The Real Relationship

Carbohydrates are your body's preferred fuel source. Understanding how to use them can transform your energy levels.

Carbs have been unfairly demonized. Here's what science says about their role in energy and performance.

How Your Body Uses Carbs

Carbohydrates break down into glucose, your brain and muscles' primary fuel source. Stored as glycogen, they provide quick energy during exercise.

Quality Over Quantity

Complex carbs (whole grains, vegetables, legumes) provide sustained energy. Simple carbs (sugar, white bread) cause rapid spikes and crashes.

Timing Carbs for Performance

Consuming carbs before and after exercise optimizes performance and recovery. This doesn't mean you need to carb-load for a walk.

Finding Your Sweet Spot

  • Start with 40–50% of calories from carbs
  • Adjust based on activity level and goals
  • Track how different amounts affect your energy
  • Use CalTrax to identify patterns over time
