Prolonged Nightly Fasting Could Help Support Metabolic Health

According to a study published online in JAMA Oncology, fasting during sleep for more than 13 hours a night may offer protection against recurrence of illness among women with early stage breast cancer. Women in the study who fasted for less than 13 hours a night had a 36% higher risk for breast cancer recurrence, compared with those who fasted for 13 or more hours. The researchers also theorized that nightly fasting and its positive effect on glycemic control and sleep could help reduce the risk of type 2 diabetes, cardiovascular disease and other cancers.
