According to a new study from the American College of Cardiology, older breast cancer survivors with cardiometabolic risk factors that limited their food intake to eight hours during the workday, followed by 16 hours of fasting, were at higher risk. low cardiovascular disease (CVD) after a few weeks. .

The research results have been published in the journal “JACC CardioOncology”.

The study is part of the upcoming mini-focus issue, “Physical Activity and Lifestyle Interventions in Cancer.”

The authors looked at 22 people with a body mass index who were classified as overweight or obese, had completed cardiotoxic therapy (anthracyclines, a commonly used chemotherapy drug) within the previous one to six years, and had an average age of 66 years old.

For eight weeks, participants were allowed to eat freely between noon and 8 p.m. on weekdays and anytime on weekends. Outside these 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 increased from 10.9% to 8.6% at the end of the trial period.

“This rigorously designed and well-executed single-arm feasibility study generates important hypotheses and questions about the role of time-restricted eating in cancer survivors,” said Bonnie Ky, MD, MSCE, Senior Editor. Head of JACC: CardioOncology.

“For example, what is the basis for inter-individual variation in response to time-restricted feeding in the Framingham risk score, and will this help identify patients most likely to benefit from this strategy? “

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