Dr. Mindy Pelz

A conversation on fasting and circadian rhythm that spends useful time on the distinction between the two things usually bundled together. A consistent daily eating window, which is what Dr Panda's research addresses, and longer or intermittent fasting protocols, which rest on a different and thinner evidence base.

His position on the daily version is well supported. The clocks in peripheral organs take their timing cue from feeding, so a repeated window acts as a signal that keeps those clocks aligned, and animal studies with matched calories showed clear protection from metabolic disease based on timing alone. The human trial literature, now spanning well over a hundred studies, is encouraging on glucose and cardiometabolic markers. Claims beyond that, particularly about extended fasting, he tends to treat with more caution than the popular conversation does.

Given Pelz's focus on women's health, there is discussion of how the advice applies across hormonal cycles and life stages, an area where the research is still developing.
