INSIGHT

Muscle Produces Ketones And Supplies NAD+

Skeletal muscle converts acetoacetate to beta-hydroxybutyrate and releases it, supplying NAD+ in the process.
This peripheral conversion may sustain cellular NAD+ and support cellular function with aging relevance.

INSIGHT

Ketones Improve Cardiac Function Acutely

Acute ketone elevation improves cardiac function (stroke volume, output) in animals and humans.
Unknown are long-term effects after repeated ketone elevation over weeks to months.

INSIGHT

Ketone Fuel Boosts Cardiac Efficiency

Hearts running on ketones appear more oxygen-efficient, producing more ATP per unit oxygen.
This metabolic efficiency may underlie improved cardiac performance, especially in heart failure.

This week’s episode of The Metabolic Link features an illuminating sit-down interview with Dr. Jeff Volek, a professor at The Ohio State University. With a PhD in Kinesiology specializing in exercise and nutrition science from Penn State University, Dr. Volek has performed cutting edge research on how humans adapt to diets restricted in carbohydrates with a dual focus on clinical and performance applications of nutritional ketosis. His scholarly work includes more than 300 peer-reviewed scientific manuscripts and five books, including a New York Times Best Seller.

In this wide-ranging interview, we cover:

💡 Unexpected normalization of muscle glycogen on ketogenic diets

💡 Muscle production of beta-hydroxybutyrate as an alternative fuel and cellular NAD+ source

💡 The emerging science on improved function of a heart muscle fueled by ketones

💡 Revisiting the FASTER study: Fitness, Aging, Stress & TBI Exposure Repository

💡 Ketogenic diets to enhance military resilience under high-stress conditions

💡 Targeting diabetic complications - studies that show hard outcomes are needed to change policy

💡 Educating physicians on therapeutic nutrition - the value of credible science-based platforms

💡 Helping address the epidemics of obesity, diabetes, and metabolic disease through lifestyle change
