Not eating for 13 hours or more between dinner and breakfast might make cancer recurrence less likely in women with early stage breast cancer.
A new study found that fasting less than 13 hours between dinner and breakfast was associated with an increased risk of a breast cancer recurrence in women with an early stage of the disease.
The study, published Thursday in JAMA Oncology, examined data from more than 2,400 women with early-stage cancer who were between ages 27 and 70 at the time of diagnosis.
It found that a nighttime fasting period of less than 13 hours was linked to a 36 percent higher risk for a cancer recurrence, compared with fasting durations of 13 hours or more. The study didn’t find a link between the shorter fasting period and an increased risk of death from breast cancer or other causes.
Given those results, “prolonging the length of the nightly fasting interval may be a simple, non-pharmacologic strategy for reducing the risk of breast cancer recurrence,” said the study authors, who were led by Ruth Patterson of the University of California in San Diego.
