Study Notes
Autophagy Definition
- Autophagy is a natural, regulated mechanism in which cells recycle and remove damaged or dysfunctional cellular components, such as proteins and organelles.
Autophagy Trigger
- Fasting is a way to induce autophagy, and the duration of fasting required to trigger autophagy varies depending on the individual and the type of fasting.
- In general, autophagy can be triggered after 12-14 hours of fasting, but it can be induced more quickly in some individuals.
- Longer fasting periods, such as 24-48 hours, can stimulate more intense autophagy.
Autophagy Purpose
- The primary purpose of autophagy is to maintain cellular homeostasis and promote cellular survival during times of stress, such as nutrient deprivation or organelle damage.
- Autophagy helps to remove damaged or dysfunctional cellular components, which can lead to cellular dysfunction and disease if not removed.
- Autophagy also plays a role in promoting cellular renewal and rejuvenation, and can help to maintain healthy cellular function.
