The document discusses ProLon, a fasting mimicking diet (FMD) developed by researchers at USC. It summarizes that FMD provides nutrition for 5 days to mimic the effects of fasting, including cellular cleaning, reduced IGF-1, weight loss and fat reduction. Clinical trials showed FMD helped reduce weight, waist circumference, blood pressure and inflammation markers while maintaining lean body mass. FMD may support health, wellness and longevity through cellular rejuvenation effects.
