Experts say you don’t need 10,000 steps, here’s the new magic number

A major systematic review finds that walking just 7,000 steps per day, rather than the traditional 10,000, can significantly reduce the risk of mortality, cardiovascular disease, dementia, and more. The analysis, published in The Lancet Public Health, provides an evidence-based and achievable target for adult health.

Gut bacteria send direct signals to the brain to stop you from overeating

Researchers have discovered a novel gut-brain sensory circuit in mice where specialized colonic cells sense bacterial flagellin and rapidly suppress feeding via the vagus nerve. This "neurobiotic sense" operates independently of immune pathways, revealing a direct neural mechanism for microbiota-host communication.
