What are fasting mimetics?
Sources:
Fasting mimetics are substances that mimic some of the biochemical effects of fasting without the need to actually fast. According to and Dr. Satchin Panda, common fasting mimetics include metformin and berberine. These substances activate pathways in cells similar to those activated during fasting, particularly the AMPK pathway, which is associated with metabolic regulation and autophagy, and inhibit mTOR, which is involved in cell growth and proliferation 1.
Key Points:
- Metformin: Activates AMPK and reduces mTOR activity, mimicking fasting-induced cellular conditions.
- Berberine: A natural compound known as the "poor man's metformin" that also lowers blood glucose and mimics fasting effects.
- Rapamycin: Another drug that mimics fasting by reducing mTOR activity, shown in studies to extend lifespan in mice and improve health 1 2.
These fasting mimetics can promote cellular repair and metabolic adjustments similar to those achieved through actual fasting, aiding longevity and health by simulating the fasting state.
