Intermittent Fasting After 55: What the Science Says — and What It Doesn't

A twelve-week clinical trial found that time-restricted eating produced a three-point-three kilogram reduction in body weight, a four-millimeter-of-mercury drop in blood pressure, and measurable improvements in metabolic markers — without requiring calorie counting. A twelve-week clinical trial published in Cell Metabolism found that adults with metabolic syndrome who adopted a ten-hour eating window — a form of intermittent fasting — without being told to restrict calories lost an average of three point three kilograms, reduced their waist circumference by three percent, and lowered their blood pressure by four millimeters of mercury.
