Short term fasting shows beneficial effects in humans, mice and yeast

A diet designed to mimic fasting over short time scales was shown to reduce health risk factors in a pilot human trial, and increased lifespan in both mice and yeast. The authors of the study, published in Cell Metabolism, suggest their ‘Fasting Mimicking Diet’ has high potential to promote human health and longevity. Continue reading
