Preliminary research indicates that individuals practicing intermittent fasting with an 8-hour eating window may face a 91% increased risk of dying from cardiovascular diseases. Analyzing data from 20,000 U.S. adults, the study found a significant association between a restricted eating schedule and elevated cardiovascular mortality compared to those eating across a more conventional 12-16 hours span.
Despite intermittent fasting’s popularity for its simplicity and potential weight loss benefits, critics argue its advantages may not significantly surpass traditional calorie counting. Recent findings presented at the American Heart Association’s scientific sessions highlight the potential dangers of the popular 16:8 fasting method.
Senior study author Victor Wenze Zhong, Ph.D., expressed surprise at the findings, emphasizing the lack of longevity benefits associated with shorter eating durations. Yet, experts caution against drawing premature conclusions, pointing out the study’s limitations, including the lack of detailed dietary content analysis and the reliance on two days of dietary intake data for categorization.
Christopher D. Gardner, Ph.D., highlighted the need to consider nutrient quality and dietary patterns, suggesting that these factors might explain the observed health risks. The study’s findings align poorly with diets recommended by the American Heart Association, which favor Mediterranean and DASH-style diets known for their heart-health benefits.
Penny Kris-Etherton, a member of the American Heart Association nutrition committee, suggests a cautious approach towards intermittent fasting, advocating for further research to clarify the study’s implications. As the health community awaits more comprehensive results, individuals practicing intermittent fasting are advised to consider the potential risks associated with their dietary choices.
