The study results were presented at the American Heart Association (AHA) conference in Chicago from March 18-21, and the paper will be published soon in a peer-reviewed journal, according to a March 19 statement from the AHA. It is said that

“However, the long-term health effects of time-restricted eating, including the risk of death from any cause or cardiovascular disease, are unclear,” he added.
This is a dietary plan that research has examined, based primarily on information obtained from the U.S. National Health and Nutrition Examination Survey (NHANES) database between 2003 and 2018, and its potential long-term health effects. was analyzed.
Nearly 20,000 adult participants were asked to complete two dietary questionnaires within one year of enrollment, and during a median follow-up of 8 years (up to 17 years), 2,797 deaths were recorded, including 840 were due to cardiovascular disease.

“Overall, this study suggests that while time-restricted eating may have short-term benefits, it may have long-term negative effects,” the study said. Christopher Gardner, a professor of medicine at Stanford University who was not involved, said in a statement from the AHA.
But both nutrition and heart disease experts say more comprehensive research is needed before a clear link between time-restricted eating and cardiovascular disease risk can be established. The research results are being questioned.
Dr. Kenneth Mukamal, a primary care physician at Beth Israel Deaconess Medical Center and a professor at Harvard Medical School who was not involved in the study, said on March 18 that many factors remain unknown. told AHA News.
Rather than focusing on when people eat, it’s important to focus on what they eat
He noted that this was an observational study rather than a randomized trial, adding that it was important to understand why people choose these diets. For example, a cancer patient may suffer from loss of appetite.
“At least for now, it’s less important to focus on when people eat and more important to focus on what they eat,” Mukamal says.
Zhang Peng, a physician at Capital Medical University’s Beijing Friendship Hospital, said the study’s conclusions would not change his hospital’s clinical operations.
“Many studies in nutrition often reach controversial conclusions under a variety of conditions. There is also no particularly clear answer for intermittent fasting, but overall the benefits outweigh the drawbacks.” There is much more evidence that,” he said.
He said the study presented at the conference was “not surprising at all” and that more detailed information about the participants, such as whether they had underlying health conditions such as type 2 diabetes or cardiovascular disease, could be used. He said this was because it was not provided.
Zhang, a doctor of bariatric medicine and metabolic surgery, said patients will be treated precisely based on category. For people who are simply obese, we recommend reducing meal times on a calorie-controlled diet, such as the 16:8 plan.
However, this time-restricted diet does not apply to people with nutritional disorders associated with diabetes, gastrointestinal disease, cardiovascular disease, or other malignancies.
He said nutrition management and weight loss were “serious” issues and urged people to consult a medical professional rather than just making their own decisions based on research.

Mukamal also said it’s premature to conclude that people should avoid time-restricted eating if it helps them achieve their weight loss goals.
“At this point, if people want to eat in a shorter period of time and it’s easier to maintain their weight that way, I wouldn’t use that as a reason not to do it,” he says.
The study authors themselves cautioned about the limitations of their findings, noting that they did not take into account factors other than daily mealtimes that may have influenced the cause of death.
They called for further research in the future, including investigating the biological mechanisms underlying the association between time-restricted eating and adverse cardiovascular outcomes.
There is growing scientific evidence that intermittent fasting may lead to short-term benefits…but almost certainly has a negative impact on longevity.
However, despite questions about the study’s greed, the researchers welcomed the results, saying people are focusing on the short-term benefits of time-restricted eating plans without fully knowing the long-term effects. Some people did.

Instead of intermittent fasting, calorie restriction is actually recommended by academia, Tian said.
“Large studies have shown that calorie restriction can lead to many beneficial changes in health indicators, including longevity,” he said.
This is not the first time that intermittent fasting has been linked to death from cardiovascular disease.
In a large prospective study of more than 24,000 adults aged 40 and older published in the Journal of the Academy of Nutrition and Dietetics in 2022, scientists found that skipping even one meal was associated with a lower risk of all-cause mortality and heart disease. They found that it was associated with an increased risk of death from vascular disease. .
