How a Ketogenic Diet May Help Reboot Fuel Delivery in the Heart

Key points

• A ketogenic diet can act as a metabolic 'reset' for the heart, switching its primary fuel from glucose to more efficient, cleaner-burning ketones like beta-hydroxybutyrate (BHB).
• BHB is not just fuel; it's a powerful signaling molecule that can switch on genes related to antioxidant defense and cellular longevity, helping to protect heart cells from stress.
• Successful adherence to a keto diet for heart health depends on more than just food; personal motivation, social support, and practical strategies for dining out are crucial.
• A well-formulated ketogenic diet for cardiac support should be rich in high-quality fats like avocados, extra virgin olive oil, MCTs from coconut, and omega-3s from fatty fish.
• Initial challenges like the 'keto flu' are common but can be managed by diligently replenishing electrolytes like sodium, potassium, and magnesium through whole foods and broths.
• This approach moves beyond simple sodium restriction, offering a root-cause solution that addresses mitochondrial dysfunction, insulin signaling, and systemic inflammation.
