Intermittent fasting may fundamentally increase your risk of dying from cardiovascular disease, according to a new study.

A study by researchers at China’s Shanghai Jiao Tong University School of Medicine found that intermittent fasting, a common eating pattern that restricts daily meals to specific times, ranging from four to 12 hours out of a 24-hour period, We investigated a wide range of things. time.

Previous studies have suggested that such eating patterns can help with weight loss and lower blood pressure, but this study found that people who followed a pattern of eating all their food for less than 8 hours a day had lower cardiovascular They were found to have a 91% higher risk of dying from the disease compared to people who ate over 12 to 16 hours over an eight-year period.

The analysis, presented Monday at the American Heart Association (AHA) Scientific Sessions in Chicago, has not yet been peer-reviewed or published in a scientific journal, but is based on data from the Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey. ing. It was collected between 2003 and 2018.

Researchers analyzed responses from nearly 20,000 adults who recorded what they ate for at least two days, and looked at who died from cardiovascular disease after an eight-year follow-up period.

The analysis also found that people with heart disease and cancer have a higher risk of cardiovascular death, and that people with pre-existing cardiovascular disease eat between 8 and 8 hours per day. They also found that 10 hours was associated with a 66% higher risk of cardiovascular death. Death from heart disease or stroke.

The researchers found that their analysis showed that time-restricted eating “did not reduce the overall risk of death from any cause” and that eating for more than 16 hours per day It added that the findings suggest that the study is associated with a lower risk of cancer death in cancer patients.

The study’s lead author, Victor Wenze Zhong, said the results were “surprising” and said: “The long-term introduction of an 8-hour time-restricted diet significantly increases the risk of cardiovascular and all-cause mortality. “We expected it to be related to a decline,” he added. death.

“We were surprised to discover that people who followed an eight-hour time-restricted eating schedule were more likely to die from cardiovascular disease. This type of diet is popular because it offers short-term benefits. However, our study clearly showed that shorter meal times were not associated with longer lives compared to the typical 12-16 hour daily meal time range. is showing.

“It is critical for patients, especially those with pre-existing heart disease or cancer, to be aware of the association between eight-hour mealtimes and increased risk of cardiovascular death.

“Our findings encourage a more measured and personal approach to dietary recommendations, ensuring they are consistent with individual health conditions and the latest scientific evidence.”

Research leaders agree more research is needed

The researchers acknowledged that the study had limitations, including its reliance on self-reported dietary information, which “could be influenced by participants’ memories and recollections, and could reflect typical dietary patterns.” It may not be possible to make an accurate assessment.”

“Other than daily meal times and cause of death, factors that may influence health were not included in the analysis,” the researchers added.

Dr. Zhong added that it is too early to make specific recommendations for intermittent fasting based solely on his research, but that people should be “very cautious” about long-term fasting patterns.

He said it was unclear why his study found an association between time-restricted eating and risk of death from cardiovascular disease.

He theorized that people who restricted their eating to less than eight hours a day may have less lean muscle mass than those who ate for 12 to 16 hours. Low lean muscle mass has been shown to increase the risk of cardiovascular death.

Dr. Pam Taub, a cardiologist at the University of California, San Diego Health, told Sky News’ US partner NBC News: Habit. ”

She added that her patients have seen “incredible benefits” from fasting therapy, adding, “I want to continue doing it. For people who do intermittent fasting, individual results are That speaks for itself,” he concluded.

“Most people who engage in intermittent fasting continue to do it because they see weight loss, lower blood pressure, and improvements in LDL cholesterol.”
