Metabolic Flexibility

Definition

Metabolic flexibility refers to the body's ability to switch between burning carbohydrates and fats for energy efficiently.

Scientific / Technical Definition

Metabolic flexibility is the capability of mitochondria within cells to adapt fuel oxidation to fuel availability, which means switching smoothly between using glucose or fatty acids as the primary fuel source depending on dietary intake and energy demands.

Benefits

• Improved energy levels.
• Better weight management.
• Enhanced athletic performance.
• Reduced risk of metabolic diseases such as type 2 diabetes.

Examples

• Improved metabolic flexibility is often seen in individuals who engage in regular physical activity.
• Metabolic flexibility can be supported by balanced diets that include both carbohydrates and healthy fats.

Additional Information

• effects: Metabolic flexibility influences energy balance, glucose regulation, and overall metabolic health.
