Autophagy is your body’s built-in recycling system, removing damaged cells and replacing them with healthy ones. But if you rely on a morning cup of joe, you might be asking: Does coffee stop autophagy?
What is Autophagy?
Autophagy translates to “self-eating”. It kicks in after about 16 to 18 hours of fasting when your body runs out of glucose and begins searching for other energy sources, eventually breaking down old cellular junk.
Black Coffee vs. Autophagy
Great news! Plain black coffee does not stop autophagy. In fact, studies show that the polyphenols in coffee actually accelerate autophagy in the liver, muscle, and brain. The caffeine also boosts ketone production, pushing you deeper into a fasted state.
What About Coffee with Milk or Sweeteners?
This is where things change. Adding milk, cream, collagen, or sugar adds calories and amino acids. Even a tiny amount of protein (like collagen) activates the mTOR pathway, which acts as a switch that instantly shuts off autophagy.
Conclusion
If you are fasting for deep cellular healing and longevity, stick to pure black coffee or green tea. Track your autophagy stages automatically with the Simple Fasting Tracker!
