Deep dives

Understanding Metabolic Flexibility

Metabolic flexibility refers to the body's ability to switch between burning fat and carbohydrates as fuel, depending on availability. For optimal metabolic health, the ability to rapidly transition from fat oxidation during fasting or low-intensity exercise to carbohydrate oxidation during higher intensity activity is crucial. This adaptation allows individuals to efficiently use stored energy, particularly in varying dietary conditions. Exercise plays a significant role in enhancing metabolic flexibility, with a focus on building muscle and engaging in high-intensity workouts effectively driving these adaptations.
