So if a breast cancer survivor usually eats dinner at 8pm and then had breakfast before 9am, she had a 36 percent greater risk of having a breast cancer “event” than if she finished her last meal of the day at 6pm and didn't eat breakfast until after 7am the following morning, said Catherine Marinac, a PhD candidate at the University of California at San Diego Cancer Center, who presented the data in a poster study titled “Intermittent fasting in breast cancer risk and survivorship: Insight from the women's healthy eating and living study” (Abstract P3-09-01).
“Prolonging the length of the nightly fasting interval may be a simple, non-pharmacologic strategy for reducing the risk of breast cancer recurrence as well as other chronic conditions with etiologic ties to breast cancer such as type 2 diabetes,” she told OT.
She and her colleagues also found that women who fasted less than 13 hours had a greater risk of breast cancer mortality—a 21 percent increase over the women who had intermittent fasting of more than 13 hours, but the difference did not reach statistical significance.
Similarly, there was a 22 percent greater risk of all-cause mortality among women who fasted less than 13 hours, but again that difference did not reach statistical significance.
