Time-restricted eating reduce cardiac risk in breast cancer survivors

According to a new study by The American College of Cardiology, older breast cancer survivors with ‘cardio metabolic’ risk factors who restricted food consumption to eight hours during the workday, followed by 16 hours of fasting, had a decreased risk of cardiovascular disease after a few weeks.

The findings of the research were published in the journal 'JACC CardioOncology'. The study is a part of the upcoming mini-focus issue – ‘Physical Activity and Lifestyle Interventions in Cancer’.

The authors looked at 22 individuals with a body mass index who were classified as overweight or obese (>25kg/m2), had completed cardiotoxic treatment (anthracyclines, a commonly used chemotherapy drugs) within the past one to six years, and were an average age of 66 years.

For eight weeks participants were allowed to eat freely between 12.00pm to 8.00pm 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.

Using the Canadian Cardiovascular Society scoring system to calculate the 10-year Framingham Risk Score, the authors found that CVD risk decreased from 10.9 per cent to 8.6 per cent at the end of the trial period.

"This rigorously designed, well-executed single-arm feasibility study generates important hypotheses and questions about the role of time-restricted eating relevant to cancer survivors," said Bonnie Ky, editor-in-chief of JACC: CardioOncology.

"For example, what is the basis of the inter-individual variation of the response to time-restricted eating in the Framingham Risk Score, and will this help identify patients who are most likely to benefit from this strategy?"

"How does diet quality affect these findings? We look forward to seeing research using practical lifestyle interventions continue to evolve and advance to improve the lives of our patients and survivors."
