Carbohydrates serve as the primary fuel source for the body during physical activity. Once consumed, they are broken down into glucose, which is used for immediate energy or stored as glycogen in the liver and muscles for later use. During exercise, especially high-intensity workouts, the body primarily relies on glycogen stores to meet its energy demands. Insufficient carbohydrate intake can lead to early fatigue and diminished performance. Therefore, athletes must carefully manage their carbohydrate consumption to ensure sustained energy levels, optimize their workouts, and support recovery processes.
