Rapid Review Quiz: Intermittent Fasting

A recent clinical study found that the FMD regimen reduced median plasma glucose concentration by 18.6% (range: -63.1% to +67.8%) and serum insulin by 50.7% (range: -91.3% to +697%). Data showed that associated weight loss was largely reversible during the healthy-eating intervals between FMD cycles. FMD-induced metabolic changes were independent of primary tumor type, concomitant anticancer treatments, and tumor stage. In contrast to previous studies, the compliance rate was 91.8% over all FMD cycles, meaning that nearly all patients were able to follow the FMD regimen.

The trial found the incidence of severe grade 3 or 4 FMD-related adverse events occurred at a rate of 12.9%, much lower than the prespecified 20% threshold. Although interleukin 6 (IL-6) plays an important role in the pathogenesis of cachexia and FMD-induced upregulation of the IL-6–SOCS3–LIF signature at the tumor level may be concerning, in this study, the FMD reduced blood IL-6 rather than increasing it, and patients maintained weight stably over subsequent FMD cycles.

Take another quiz on recent diet and nutrition studies.
