The Impact of 8-Hour Time-Restricted Eating on Cardiovascular Health
Time-restricted eating (TRE) has gained popularity for weight loss and improved heart health, but recent research suggests that an 8-hour time-restricted eating schedule may be associated with a higher risk of cardiovascular death. The study analyzed data from over 20,000 U.S. adults and found that those who followed an eating schedule of less than 8 hours per day had a 91% higher risk of death from cardiovascular disease compared to those who ate across 12–16 hours per day. This increased risk was also observed in individuals with pre-existing heart disease or cancer. Contrary to expectations, limiting eating to less than 8 hours per day did not lead to a longer lifespan compared to a 12–16 hour eating window. Additionally, an eating duration of more than 16 hours per day was associated with a lower risk of cancer mortality among individuals with cancer. These findings suggest that while time-restricted eating may offer short-term benefits, there may be long-term risks, particul...
