What actually happens to your heart when you practice intermittent fasting? In this deep dive from Science Explained, we move beyond fear-based assumptions and examine the real physiology behind cardiac metabolism during fasting. Your heart beats nearly 100,000 times per day and relies on continuous energy production — but does that require continuous eating?

In this episode of Science Explained, we break down the metabolic timeline step by step: from the fed state and insulin signaling to glycogen depletion, fatty acid oxidation, and ketone utilization. You’ll learn why the heart primarily burns fat even in the fed state, how ketones function as an efficient fuel source, and what mitochondrial adaptation means for long-term metabolic flexibility.

We also examine oxidative stress, autophagy, electrolyte balance, blood pressure regulation, and the 2024 cardiovascular mortality study that generated widespread headlines. Rather than reacting to surface-level claims, Science Explained analyzes mechanisms, limitations of observational research, and what current evidence actually supports.

Is fasting dangerous for the heart? Does it increase arrhythmia risk? What role do sodium and potassium play during extended fasting windows? This video clarifies the difference between metabolic flexibility and metabolic rigidity — and why the heart is more adaptable than most people realize.

As always, Science Explained focuses on education, not medical prescription. If you have cardiovascular disease or take heart-related medications, consult your physician before changing eating patterns.

Watch now to understand how fasting truly impacts cardiac function — only on Science Explained.
