Does Intermittent Fasting Cause Heart Disease?
Hi there, fellow fasters,
Intermittent fasting has been a hot topic lately, especially after recent research presented at the American Heart Association’s scientific sessions suggested a 91 percent increased risk of death from cardiovascular disease associated with intermittent fasting. However, before jumping to conclusions, let’s dive deeper into the data and consider different perspectives on this controversial topic.
American Heart Association Session: Preliminary Findings and Potential Limitations on Intermittent Fasting Data
The preliminary research presented at the scientific sessions utilized data from the National Health and Nutrition Examination Survey, involving approximately 20,000 participants tracked over an average of 8 years. The session found that participants reporting a shorter eating window of 8 hours or less had a significantly increased risk of death from cardiovascular disease.
While these findings may sound alarming at first, it’s important to approach them with caution. The research has not yet undergone peer review or been published, which is common for studies presented at scientific sessions. Additionally, the session relied on self-reported dietary data from a survey, with only two days of eating recorded as participants’ usual food intake patterns.
Potential Confusing Factors and Alternative Interpretations
There are several factors to consider when interpreting the results of this session. Firstly, the session did not account for potential confounding variables such as smoking, stimulant drug use, or socioeconomic status, which may influence both meal-skipping behavior and cardiovascular risk.
Moreover, previous randomized controlled studies and meta-analyses have demonstrated benefits for cardiovascular health with intermittent fasting. For example, a long-term session involving heart patients who underwent cardiac catheterization showed that intermittent fasting was protective against heart failure and contributed to increased longevity.
I also want to point out this scientific session the AHA put out regarding regular fasting as a benefit.
Critique of the American Heart Association’s Position
On the other hand, critics have raised concerns about the American Heart Association’s stance on intermittent fasting. Given the organization’s history of promoting dietary guidelines that have faced criticism, such as low-fat diets and high-carb recommendations like Cheerios, some question the credibility of their opposition to intermittent fasting.
Furthermore, the lack of clarity regarding the participants’ actual fasting practices raises skepticism about the validity of the session’s findings. It’s possible that the observed increased risk of cardiovascular disease was not directly attributable to intermittent fasting but rather to other dietary or lifestyle factors.
Practical Recommendations and Takeaways
Despite the conflicting evidence and controversy surrounding intermittent fasting, it’s essential for individuals considering this dietary approach to approach it cautiously and responsibly. Over-fasting or inappropriate fasting practices, especially among women, may have adverse effects on metabolic health.
Instead of dismissing intermittent fasting outright based on preliminary findings, individuals should focus on adopting balanced and sustainable dietary habits that prioritize overall health and well-being. Consulting with healthcare professionals and registered dietitians can help individuals develop personalized nutrition plans that align with their specific needs and goals.
So, while the recent session on intermittent fasting and cardiovascular risk has sparked debate and raised questions, further research is needed to validate these findings and provide more conclusive evidence. In the meantime, it’s crucial for individuals to approach dietary choices with critical thinking and consider a holistic approach to health and wellness.
