What is time-restricted eating?

There are several types of intermittent fasting, but they all follow the same concept of alternating fasting and eating.

The Department of Epidemiology and Biostatistics, School of Medicine, Shanghai Jiao Tong University, Shanghai, China, said in a statement.

“But in the long run, Health effects The risks of time-restricted eating, including the risk of death from any cause or cardiovascular disease, are unknown. ”

What are the details of the study?

Researchers from Shanghai Jiao Tong University School of Medicine in Shanghai, China, analyzed information from the annual National Health and Nutrition Examination Survey (NHANES) from 2003 to 2018.

They compared that to deaths recorded by the Centers for Disease Control and Prevention (CDC) between 2003 and December 2019.

A new study published by the American Heart Association (AHA) shows that a group of 20,000 adults who followed an 8-hour time-restricted eating schedule had a 91% higher risk of dying from heart disease than the time-restricted group. It has been found. Meals take 12 to 16 hours. (St. Petersburg)

Those who ate all of their daily meals within eight hours had the highest risk of cardiovascular death (91%), followed by those who ate within 8 to 10 hours (66% risk).

An increased risk of heart-related death was also found in people with pre-existing heart disease. or cancerstated in the release.

“While this type of diet has been popular due to its potential short-term benefits, our study shows that compared to the typical eating window range of 12 to 16 hours per day, “This clearly shows that short time spans are not associated with longevity,” Zhong said in the release.

The researchers followed the participants for an average of eight years, and some for as long as 17 years.

The average age of participants was 49 years.

What are the limitations of the study?

Dr. Lou Badramani, a cardiologist and founder of Vital Solutions, an Ohio company that provides cardiovascular and anesthesiology services to hospitals across the country, was not involved in the study but has some insight into the results. provided insight.

“As with all research, the devil is in the details,” he says. “This study provides food for discussion and encourages further research, but it is far from conclusive.”

Fasting habits were based on just two days of records eating habitsVadlamani pointed out – and it all depended on the recollections of the participants.

“There was no documentation of what the participants ate while they were not fasting or what their activity levels were.” There was also no documentation of the timing of the fast, whether it occurred during the day or at night. It was not clear whether he had been injured. (St. Petersburg)

“It would be a stretch to say conclusively and with certainty that fasting has a direct effect on the incidence of heart attacks,” the cardiologist said.

“Since intermittent fasting has become so common, this certainly raises many questions and supports the need for more comprehensive research.”

Lauren Harris Pincus, R.D., author of The Everything Easy Pre-Diabetes Cookbook, said the study has not yet been fully published or peer-reviewed, meaning a full analysis of the study’s results has not yet been completed. He warned that it was “premature” to do so.

“There appears to be an important variation between the short-term benefits and long-term risks of time-restricted diets.”

She was also not involved in the study.

“While this may suggest a correlation between intermittent fasting and death from cardiovascular disease, it does not prove causation,” a New Jersey-based expert told FOX News Digital. Ta.

“There appears to be an important distinction between the short-term benefits and long-term risks of time-restricted diets.”

She added: “This conclusion negates the positive benefits of time-restricted eating in a series of previous studies, and furthermore, the data were based on self-reported food records at several points in time.” added.
