Episode notes
Multiple Mechanisms Of Fat Burners
- Fat burners work via multiple vectors: lipolysis, RMR increase, appetite suppression, and repartitioning.
- Caffeine exemplifies repartitioning by increasing fat use during exercise and sparing glycogen.
Caffeine Shifts Fuel Use Toward Fat
- EG: Caffeine shifts substrate use toward fat and raises postprandial thermogenesis.
- Even when insulin is high, caffeine can increase fat breakdown relative to no caffeine.
Use Yohimbine Only Fasted
- Take yohimbine HCl fasted 30–60 minutes before cardio to maximize FFA release.
- Avoid taking yohimbine with food because insulin suppresses its effect.
