It’s over for protein at every meal: what a USC laboratory removes from the day to restart cell recycling
Scientists at USC’s Longevity Institute have identified protein restriction as the key to triggering autophagy, the body’s cellular cleanup process. A five-day fasting-mimicking diet cycle showed measurable results: participants reversed biological aging by 2.5 years, lowered insulin resistance, and activated the same genetic switches used in stem-cell reprogramming—all without traditional fasting’s downsides.
