Time-restricted feeding normalizes hyperinsulinemia to inhibit breast cancer in obese postmenopausal mouse models

Abstract

Obesity and its associated metabolic changes, including hyperinsulinemia and aberrant circadian rhythms, increases the risk for a variety of cancers including postmenopausal breast cancer. Here, the authors show that restricting when mice eat, but not what or how much they eat, delays breast cancer initiation and reduces tumor growth in obese mice in addition to improving insulin sensitivity and restoring circadian rhythms.
