FASTING NEWS
Here's why fasting improves longevity and brain health
Fasting—or restricting the calories in your diet— seems to improve our health and help us live longer, but scientists have only recently discovered why.
It seems related to a gene, OXR1 (Oxidation Resistance 1), that influences longevity and brain health. Although fasting may affect the gut, it also helps genes that protect the brain from neurological diseases, say researchers from the Buck Institute for Research on Aging.
