In this episode, we explore the science of metabolism—what it is, how it works, and how you can optimize it. Metabolism comprises your Basal Metabolic Rate (BMR), the Thermic Effect of Food (TEF), and activity-related energy expenditure, including non-exercise activity thermogenesis (NEAT). NEAT refers to the energy you burn through daily movements like fidgeting, standing, and walking, which can significantly contribute to your total calorie expenditure, particularly for those with sedentary lifestyles. Factors such as age, genetics, body composition, and lifestyle heavily influence metabolism. Strength training helps build muscle, which increases BMR, while High-Intensity Interval Training (HIIT) enhances calorie burn during and after exercise. Nutrition plays a vital role too—protein has the highest thermic effect of food, and hydration is essential for maintaining metabolic efficiency.
Rather than drastic changes to metabolism itself, shifts in lifestyle, nutrition, and activity levels influence how efficiently it functions throughout life stages. Incorporating strength training and ensuring adequate protein intake are particularly important as we age to support muscle mass and overall metabolic health. Common beliefs, such as the idea that eating frequent small meals boosts metabolism or that taking one supplement can hack your metabolic speed, don’t hold up under scientific scrutiny. Instead, we discuss practical strategies for optimizing metabolism that are supported scientifically. While there are no quick fixes, sustainable habits can profoundly support your health and wellness goals. Tune in to learn how to work with your metabolism to feel and function at your best.

Cardiac Cowboys
The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
