In this Huberman Lab Essentials episode, I explore how the nervous system impacts fat loss and how certain behaviors and supplements can accelerate fat burning. I explain how non-exercise movements like fidgeting and shivering trigger adrenaline to boost fat metabolism. I also examine the impact of exercise intensity and fasted workouts on fat burning, and how supplements such as caffeine, GLP-1 and berberine can further support fat loss. These science-based tools go beyond traditional calorie counting to enhance metabolism and improve body composition.
