We conducted a pilot randomized clinical trial to examine the effects of the fasting-mimicking diet (FMD) on autophagic flux and metabolic health markers in healthy humans. Thirty healthy participants were randomized to two oral formulations of FMD (ProLon and FMD2) or control for 8 days. Blood was collected at baseline, days 4 and 6 during intervention, and 48 h after completing FMD (Day 8). Effects on autophagic flux were me...

Rapamycin (RAPA) and related mTOR-inhibitors have been shown to enhance healthy aging in animal models (2–10) and to be generally safe and tolerable in older people (11–13). However, studies to assess their effects on specific age-related pathologies in humans are limited. Since improvements in cardiovascular function with RAPA treatment have been reported in preclinical studies (5, 9, 10, 14–17), we posited that RAPA could be...
