Fat Fasting: Can Eating Fat Help You Fast Longer?
✨ Key Takeaways
- Learn the best practices of intermittent fasting for optimal health.
- Understand how to track your fasting windows effectively.
- Discover the science-backed metabolic benefits of fasting.
Have you ever struggled to get through a 16-hour fast without feeling shaky or ravenous? Enter the Fat Fast. This controversial yet highly effective technique involves eating small amounts of pure fat during your fasting window.
What is a Fat Fast?
A fat fast is a variation of dirty fasting. Instead of consuming zero calories, you consume up to 200 calories of pure fat (like MCT oil, butter, or heavy cream in your coffee). Because pure fat triggers virtually no insulin response, your body remains in a fasted, fat-burning state.
How Fat Fasting Works (Ketosis)
When you consume pure fat, your body quickly converts it into ketones. This gives your brain instant energy, completely eliminating hunger cravings. This is incredibly helpful for beginners adapting to longer fasts.
Does it Break Autophagy?
Yes. While fat fasting keeps you in ketosis and promotes weight loss, consuming calories (even fat) pauses the cellular repair process of autophagy. Use fat fasting for weight loss, not for deep healing.
Conclusion
If you need help pushing past 16 hours, try adding a tablespoon of MCT oil to your morning coffee. Log your meals using the Simple Fasting Tracker app!
