Fasting-Mimicking Diet Explained
- The fasting-mimicking diet provides just enough nutrients to 'fly under the radar' of nutrient sensors.
- This tricks cells into gaining fasting benefits without undergoing full starvation.
Cells’ Survival During Starvation
- Cells survive starvation by recycling less valuable parts through autophagy for nutrients.
- They discard old components and regrow new ones when food becomes available again.
Use Fasting Occasionally for Benefits
- Fasting-mimicking diet can be done just a few times per year for profound health benefits.
- This intermittent stress triggers regenerative cellular changes without daily fasting.
