How does metabolic flexibility impact the ability to switch between burning fat and carbohydrates?

Metabolic flexibility impacts the ability to switch between burning fat and carbohydrates by determining how efficiently the body can adapt to different energy sources. Individuals with high metabolic flexibility can easily transition between using fats and carbohydrates for fuel based on availability and demand. Improving metabolic flexibility through diet and exercise, such as incorporating periods of fasting and varying carbohydrate intake, can enhance fat burning and overall metabolic health.
