Time Course for Fasting-induced Autophagy in Humans

Researchers registered this 2021 human study to track autophagy, the process cells use to break down and recycle worn-out parts, during fasting. They planned to measure changes at different times after people stopped eating. The record does not provide the number of participants, detailed methods, or results. It therefore does not show whether fasting reliably increases autophagy in people.

What this means for you: This record is not enough to guide fasting, supplements, or products claiming to boost autophagy. You can treat claims about a precise fasting time for human autophagy as unproven until results are available.
