Autophagy is a cellular process that helps maintain homeostasis by degrading and recycling damaged cellular components. Fasting can stimulate autophagy, as the absence of nutrients prompts cells to initiate this cleanup mechanism. During autophagy, senescent cells, which are aged or dysfunctional cells, can be targeted and removed, thereby promoting healthier cellular environments. This process is believed to contribute to improved metabolic health and potentially extend lifespan. The thing we h
