Intermittent Fasting Raises Concerns About Heart Disease Risk: Study

A recent study presented at a medical meeting in Chicago has raised concerns about the safety of intermittent fasting, a popular weight loss strategy. The study found that limiting mealtimes to just eight hours a day was associated with a significant increase in the risk of death from heart disease by 91%.

Study Findings and Speculations

The research, published by the American Heart Association (AHA), analyzed data from approximately 20,000 adults included in the US Centers for Disease Control and Prevention’s National Health and Nutrition Examination Survey. However, the study’s abstract provided limited details, leaving scientists to speculate about the specific protocols used.

Scrutiny and Expert Opinions & Need for Long-term Studies

The study’s findings have prompted scrutiny from experts, particularly concerning potential biases in the comparison between fasting patients and those with different mealtime patterns. Some experts suggested that underlying health differences between the groups could have influenced the results.

Keith Frayn, emeritus professor of human metabolism at the University of Oxford, emphasized the importance of long-term studies to understand the effects of intermittent fasting accurately. He noted that while the study underscores the need for further research, many questions remain unanswered.

Data Analysis and Participant Profile & Key Takeaways

Led by Victor Zhong of the Shanghai Jiao Tong University School of Medicine, the study analyzed questionnaire responses and death data from 2003 through 2019. The participants, primarily men with a mean age of 48, were assessed for various health factors, including hypertension, diabetes, and cardiovascular disease.

Despite efforts to control for variables such as age and BMI, the study found a significant association between 8-hour time-restricted eating and cardiovascular mortality. However, questions remain regarding the duration of intermittent fasting and its long-term effects on health outcomes.

As intermittent fasting gains popularity as a weight loss strategy, further research is needed to elucidate its potential risks and benefits, emphasizing the importance of evidence-based dietary recommendations for overall health and well-being.
