Energy Metabolism: Optimal Functioning of the Body
Energy metabolism is responsible for producing the necessary energy to meet the body’s needs.
Maintaining adequate levels of metabolic indicators is essential to ensure proper metabolic function and, consequently, overall health.
Glucose: The Body's Main Energy Source
Glucose is the body’s primary fuel. During anaerobic glycolysis (in the absence of oxygen), glucose is converted into lactate to produce energy. This process is especially relevant during intense exercise when the demand for energy increases significantly.
Glucose is also the key biomarker for diagnosing diabetes. Monitoring blood glucose levels is crucial for preventing and managing this disease. In many cases, diabetes can be prevented through lifestyle changes:
- Balanced diet: Rich in fruits, vegetables, whole grains, and low in sugars and saturated fats.
- Regular exercise: At least 150 minutes of moderate physical activity per week.
- Weight management: Maintaining a healthy weight to reduce the risk of diabetes.
Ketone Bodies: Alternative Energy Source
Ketone bodies serve as an alternative energy source, especially when carbohydrate levels are low. In situations of hypoglycemia, ketone bodies can provide vital energy to the nervous system.
Increasing ketone body levels:
- Low-carbohydrate diet: Reduces carbohydrate intake to promote ketone body production.
- Intense exercise: Increases energy demand and promotes ketone body production.
Amino Acids: Tyrosine and Alanine
The amino acids tyrosine and alanine play important roles beyond protein synthesis.
Tyrosine
- Boosts energy: Increases energy levels and physical performance.
- Cognitive flexibility: Helps maintain mental sharpness.
Alanine
- Glucose production: Can be used to produce glucose, contributing to reduced muscle fatigue.
- Sports performance: Helps enhance physical performance and combat fatigue.
