AdvertisementFollowing a diet that mimics fasting for five days a month appeared to reverse people's biological age by two and a half years on average in a study. These factors can be used to measure biological age, the authors of the study published January 20 in Nature Communications, said. While chronological age refers to how many years someone has been alive, biological age is a measure of how well cells and tissues are functioning. On day one of the FMD, participants ate around 1,100 calories, and around 720 on days two to five. Cultivating a sensible exercise habit could achieve the same or even better results, Clancy said, and is maintainable into older age.
