TUESDAY, March 19, 2024 (HealthDay News) — Intermittent fasting may be bad for your heart, new research warns.
Results showed that people who restricted their meals to within eight hours had almost twice the risk of heart-related death compared to those who ate freely.
The researchers noted that this contradicts previous research showing that intermittent fasting improved several indicators related to heart health, including blood pressure, blood sugar, and cholesterol levels.
“We were surprised to learn that people who followed an eight-hour time-restricted eating schedule were more likely to die from cardiovascular disease,” said Victor Wenze Zhong, senior researcher at the Department of Epidemiology and Biostatistics, Graduate School of Shanghai Jiao Tong University. ” he said. Shanghai medicine.
“While this type of diet was popular due to its potential short-term benefits, our study found that compared to the typical eating window of 12 to 16 hours per day, “Our results clearly show that less time is not associated with longer life,” Zhong added in an American Heart Association (AHA) news release.
For the study, Zhong and colleagues analyzed data from more than 20,000 U.S. adults who participated in the federal annual survey on health and nutrition from 2003 to 2018. The study tracked participants’ eating patterns.
Researchers found that most people who follow a time-restricted fast tend to eat all their food within eight hours and then fast for the rest of the day.
Researchers compared dietary data with national death records and found that people who tended to eat their entire meal within eight hours each day had a 91% higher risk of dying from heart disease.
This increased risk also applies to people who have already been diagnosed with heart disease.
Researchers found that for people with heart disease, restricting food intake to within 10 hours increases the risk of death from heart disease or stroke by 66%.
“It is critical for patients, especially those with pre-existing heart disease or cancer, to be aware of the association between the eight-hour meal window and increased risk of cardiovascular death,” Zhong said. “Our findings encourage a more measured and personalized approach to dietary recommendations, ensuring they are consistent with individual health conditions and the latest scientific evidence.”
Overall, time-restricted eating did not reduce the risk of death from any cause.
However, Zhong pointed out that the study was not designed to prove a causal link between intermittent fasting and heart-related deaths.
More research is needed to better understand why time-restricted eating negatively impacts heart health, Zhong said.
Christopher Gardner, a professor of medicine at Stanford University, said it will be important to track differences in people who practice intermittent fasting.
“For example, were the groups with the shortest eating times unique in terms of weight, stress, and traditional cardiometabolic factors compared to people following other eating schedules? [heart] What risk factors or other factors are associated with adverse cardiovascular outcomes? ” said Gardner, who was not involved in the study.
The new study was presented Monday at the American Heart Association’s Epidemiology and Prevention Science Session in Chicago. Research results presented at medical conferences are considered preliminary until published in a peer-reviewed journal.
