Eat Fast and Live Longer – At the Rancho Mirage Writers Festival: If the idea of living longer has ever intrigued you, Dr. Valter Longo’s Fasting Mimicking Diet (FMD) may be the secret. New research shows that periodically adopting a diet that mimics the effects of fasting may yield a wide range of health benefits including losing that belly weight, improving cognitive function and living better and longer.
