Implementation of weekday time‐restricted eating to improve metabolic health in breast cancer survivors with overweight/obesity
Authors' conclusion
Eight weeks of telephone-delivered weekday TRE is a feasible, acceptable, low-symptom, and low-cost intervention. Future studies may consider a longer intervention length for more consistent metabolic improvements and counseling to enhance protein intake.
