Confused about "fat burning" versus actual fat loss? Learn why you can be "burning fat" during workouts while not losing body fat.
Today I break down the difference between fat oxidation (using fat for fuel) and fat loss (reducing stored body fat) that most people misunderstand.
You'll discover how the Randle Cycle affects metabolism, why fasted cardio isn't the magic bullet you've been told, and why your nutrition and lifting weights approach matter far more for body recomp than what fuel you're burning in the moment.
We clear up some misunderstandings about low-carb diets (keto and carnivore), being fat adapted, and what's actually most important for fat loss.
Main Takeaways:
- Fat oxidation (burning fat for fuel) and fat loss (reducing stored body fat) are completely different physiological processes
- The Randle Cycle explains why carbs temporarily suppress fat burning, but this doesn't make low-carb diets superior
- Low-carb diets increase fat oxidation but don't produce better fat loss results when calories and protein are equated (in fact, sometimes the opposite is true)
- For successful fat loss, focus on what directly influences body composition
- Adopting an engineering mindset means optimizing for outcomes (fat loss) rather than processes (fat oxidation)
