Beneficial Gut Microbiome Remodeled During Intermittent Fasting in Humans.
Intermittent fasting (IF) is the practice of restricting food intake for 12-48 hours per fasting cycle over a prolonged period of time. Previous study shows beneficial health effects such as weight loss and lower risk for cardiometabolic diseases. Although reduced calorie intake may account for some of the observed benefits of IF, exact mechanisms are still unclear. Recent evidence indicates that IF may lead to remodeling and increased taxonomic diversity in the human gut microbiome. In particular, the Lachnospiraceae family of anaerobic bacteria increased during fasting. This family, in the order Clostridiales, promotes butryogenesis in the gut, a process that is associated with healthful metabolic and prolongevity effects. IF-associated alterations to the microbiome may play a key role in the metabolic and potential healthspan-enhancing benefits of IF and dietary restriction.

Rejuvenation Research coverage includes:
Cell immortalization and senescence
Pluripotent stem cells
DNA damage/repair
Gene targeting, gene therapy, and genomics
Growth factors and nutrient supply/sensing
Immunosenescence
Comparative biology of aging
Tissue engineering
Late-life pathologies (cardiovascular, neurodegenerative and others)
Public policy and social context.
