Carbs have been unfairly demonized. Here's what science says about their role in energy and performance.
Carbohydrates break down into glucose, your brain and muscles' primary fuel source. Stored as glycogen, they provide quick energy during exercise.
Complex carbs (whole grains, vegetables, legumes) provide sustained energy. Simple carbs (sugar, white bread) cause rapid spikes and crashes.
Consuming carbs before and after exercise optimizes performance and recovery. This doesn't mean you need to carb-load for a walk.
