Mitochondria and Keto: How Low-Carb Eating Boosts Cellular Energy
Mitochondria are the cellular powerhouses that convert nutrients into ATP (adenosine triphosphate) — the energy currency all cells use. The ketogenic diet profoundly enhances mitochondrial function.
Ketones Are Superior Mitochondrial Fuel
Glucose produces ~36 ATP molecules per cycle with significant reactive oxygen species (ROS) byproducts. Ketones (specifically BHB) produce ~25% more ATP per molecule with significantly fewer damaging ROS.
Mitophagy: Cleaning Out Old Mitochondria
Keto and fasting stimulate mitophagy — the selective recycling of damaged mitochondria. Removing dysfunctional mitochondria allows newer, more efficient ones to predominate, improving overall cellular energy production.
Mitochondrial Biogenesis
Exercise combined with keto powerfully stimulates mitochondrial biogenesis — the creation of new mitochondria. More mitochondria per cell means more energy capacity and better fat burning.
Keto and Age-Related Mitochondrial Decline
Mitochondrial dysfunction is central to the ageing process. By improving mitochondrial efficiency, reducing oxidative stress, and stimulating mitophagy, keto may slow age-related energetic decline.
