Additionally, the Krebs cycle (also known as the citric acid cycle) and the electron transport chain (ETS), both critical components of aerobic respiration, operate more efficiently, enhancing the body's ability to generate ATP. Furthermore, the body becomes more efficient at metabolizing fats, allowing for more prolonged energy production from fat reserves.
