Important points:
- Restricting meal times was associated with an increased risk of death from heart disease.
- This was less than 8 hours, compared to the US average of 12 to 16 hours.
Time-restricted eating windows of less than 8 hours were associated with an increased risk of cardiovascular death, according to study results presented at the Scientific Sessions on Epidemiology, Prevention, Lifestyle, and Cardiometabolism.
“Restricting your daily diet to a short period of time, such as eight hours a day, has become popular in recent years as a way to lose weight and improve heart health.” Dr. Victor Wenze Zhong, Professor and Head of the Department of Epidemiology and Biostatistics, School of Medicine, Shanghai Jiao Tong University, said in a press release. “However, the long-term health effects of time-restricted eating, including the risk of death from any cause or cardiovascular disease, are unknown.”
The study included 20,078 participants aged 20 years and older from the National Health and Nutrition Examination Survey from 2003 to 2018 who completed two 24-hour valid dietary recalls and reported normal dietary intake. self-reported (mean age 49 years, 50% male). ; 73% white). Participants were stratified based on average eating window: less than 8 hours, 8–10 hours, 10–12 hours, 12–16 hours, or 16 hours or more.
Meals within 12 to 16 hours were identified as the average meal time in the United States and were used as the reference group.
Median follow-up was 8 years.
Compared to the reference group, meal times <8 hours were associated with increased risk of cardiovascular disease mortality (HR = 1.91; 95% CI, 1.2-3.03), also observed in the subgroup of adults with CVD. (HR = 2.07; 95% CI, 1.2-3.03). 95% CI, 1.14-3.78) and cancer (HR = 3.04; 95% CI, 1.44-6.41).
According to the publication, no mealtime was associated with CV mortality (HR = 1.66), except for hours 8 to 10 and hours 12 to 16 (HR = 1.66, 95% CI, 1.03 to 2.67) among adults with CVD. , 95% CI, 1.03-2.67).
Furthermore, Zhong et al. reported that there was no significant association between Adult cancer patients (HR = 0.47; 95% CI, 0.23-0.95).
“It is critical for patients, especially those with pre-existing heart disease or cancer, to be aware of the association between the 8-hour meal window and increased risk of cardiovascular death. “We encourage a more careful and individualized approach to dietary recommendations, ensuring they are consistent with individual health conditions and the latest scientific evidence,” Zhong said in the release. Stated. “Although this study confirmed an association between an 8-hour eating window and cardiovascular death, this does not mean that time-restricted eating caused cardiovascular death.”
