Scientists from the University of Toronto found that older breast cancer survivors who restricted food intake to eight hours during the weekday, followed by 16 hours of fasting, lowered their risk of heart disease after a few weeks.
The research is published in JACC: CardioOncology and was conducted by Amy A.Kirkham et al.
People who practice time-restricted eating typically eat during an 8- to 12-hour daytime window and fast during the remaining 12 to 16 hours.
Unlike intermittent fasting, which involves caloric restriction, time-restricted eating permits a person to eat as much as they want during the eating window.
Some studies show that time-restricted eating helps not only to reduce calorie intake but also helps improve cognition and has anti-inflammatory effects.
In the current study, the team examined 22 overweight breast cancer survivors with an average age of 66 years.
For eight weeks, these were allowed to eat freely between 12-8 p.m. on weekdays and at any time on the weekends.
Outside of those hours, participants were asked to consume only water, black coffee or black tea.
The team found that their heart disease risk decreased from 10.9% to 8.6% at the end of the study.
The finding suggests that time restricted eating could benefit heart health in breast cancer survivors.
Researchers look forward to seeing future work using practical lifestyle interventions continue to improve the lives of our patients and survivors.
