Intermittent fasting isn't just about calories—it's about timing. Michael J. Wilkinson, M.D., F.A.C.C., F.N.L.A., explains how time-restricted eating aligns daily food intake with the body's natural circadian rhythms. He shares insights from animal studies, clinical trials, and UC San Diego research showing how consolidating meals into an 8–10 hour window can improve glucose control, blood pressure, and metabolic health. Wilkinson highlights why earlier eating windows may work best, what makes studies succeed or fail, and how these findings point to practical strategies for preventing cardiometabolic disease and supporting healthy aging.
