Fasting up regulates longevity genes and increases both the mean and maximum lifespan of laboratory animals. Ive done fasting on and off for the last ten years. Most people freak out if they find out that I'm fasting. Recently Ive become interested other things found in food and herbs that up-regulate longevity genes. Some berry and seed extracts have increased lifespan 28% more than fasting when eaten between fasts. Ive started writing about what I'm finding so if you are interested here are the links.
