Time-restricted eating linked to 91 per cent higher risk of cardiovascular death

According to a study conducted by the Shanghai Jiao Tong University School of Medicine, time-restricted eating, or intermittent fasting, could be linked to a higher risk of dying from heart disease.
The analysis, presented at the American Heart Association's scientific sessions in Chicago on Monday, is based on data collected by the Centres for Disease Control and Prevention between 2003 and 2018.
It's too early to reject intermittent fasting — which promotes better sleep and metabolic function because it's better aligned with circadian rhythms — based on one study alone. Moreover, scientists haven't explained exactly why time-restricted eating could heighten the risk of cardiovascular death. Just because it could reduce muscle mass over time doesn't imply that intermittent fasting may kill its followers. This research must be peer-reviewed before it can rock the scientific consensus on healthy diets.
The "16:8" diet has become an increasingly popular way to lose weight. However, intermittent fasting can increase cravings, which may lead to unhealthy food choices. While it could be beneficial in the short term, intermittent fasting's long-term effects must be investigated, particularly with people who are already predisposed to cardiovascular death. This research doesn't suggest any recommendation against the fad; it simply recommends caution for those who have been doing time-restricted eating for years.
There's a 50% chance that at least 7.1% of US adults will self-report to follow a vegetarian diet in 2028, according to the Metaculus prediction community.
