When you eat may matter as much as what you eat.
In a study of more than 2,400 women with early-stage breast cancer, those who fasted fewer than 13 hours overnight had about a 36% higher risk of recurrence than those who fasted longer.
A longer overnight fast gives insulin time to fall and cells time to repair. This is not considered extreme as dinner could end at 7 p.m., and then breakfast at 8 a.m. gets you there.
A helpful hint is to try closing the kitchen three hours before bed this week.
It is important to note that during active treatment, if you're losing weight unintentionally, talk with your care team first. Fasting isn't right for every phase so be sure to contact our team to learn more.
