That's about where my frequency is, quarterly multi-day IFs. As research becomes more specific, we'll be able to confirm the optimum frequency, but the variable for those who are fat burners may have an influence on the ideal frequency as well. I'm relying on people like Ben Bikman, Mark Mattson, Jason Fung, Dom D'Agostino, Attia, and others who have a history of recommending IF as a companion to a healthy WOE to optimize vitality and longevity.
