Is a 16-Hour Fast Sufficient for Autophagy?

One approach to autophagy-inducing fasting is to consume your regular meals one day and then fast the next day. Research indicates that while the exact timeframe for initiating autophagy can vary, a fasting period of at least 16 hours is generally believed to be necessary for the process to commence. Autophagy then begins to effectively recycle cells within a timeframe of 24 to 48 hours.
