Health expert Dr. Michael Mosley recently addressed concerns regarding intermittent fasting, a widely adopted weight loss strategy, amidst claims that it could pose risks to heart health.
Intermittent fasting, a dietary regimen where meals are consumed only within specific time windows, forms the core of various popular diets, including Dr. Mosley's renowned 5:2 and Fast 800 plans. The 16:8 diet, notably followed by celebrities like Jennifer Aniston and Heidi Klum, involves consuming all food within an eight-hour period and fasting for the remaining 16 hours.
However, a recent study involving 20,000 American adults, predominantly adhering to the 16:8 schedule, revealed concerning findings regarding its long-term health implications. The study, published in the American Heart Association Journal, suggested a potential increase in heart disease mortality among those practicing intermittent fasting, particularly within an eight-hour eating window. Dr. Mosley expressed surprise at these results, noting various complexities in interpreting the study's findings.
Contrary to these findings, Dr. Mosley referenced comprehensive research published in the New England Journal of Medicine in 2019, highlighting the broad-spectrum benefits of intermittent fasting for conditions such as obesity, type 2 diabetes, cardiovascular diseases, cancers, and neurologic disorders. He emphasized the need for cautious interpretation of recent studies, citing uncertainties regarding participant demographics, health status, and dietary habits.
Dr. Mosley raised concerns about the possibility of confounding factors influencing the study's outcomes, such as the inclusion of shift workers with inherently higher heart disease risks and the lack of dietary information during the specified eating window. Despite these concerns, Dr. Mosley maintained his confidence in intermittent fasting, indicating that his faith in its efficacy remains unshaken.
He cited additional research published in Nature Communications, which suggested that consuming breakfast before 8 am and abstaining from food for 12-13 hours afterward led to significant reductions in heart disease risks. Conversely, eating after 9 pm was associated with an increased risk of heart disease. Dr. Mosley reiterated the importance of considering meal timing for optimizing health outcomes.
Notably, the authors of the recent study also expressed surprise at their findings. Lead author Dr. Victor Wenze Zhong emphasized the lack of conclusive evidence linking time-restricted eating to cardiovascular disease mortality, urging caution in interpreting the study's results. Dr. Christopher Gardner of Stanford University highlighted the limitations of relying on self-reported dietary data, which may be subject to memory bias and inaccuracies.
In conclusion, while recent studies raise questions about the long-term implications of intermittent fasting on heart health, Dr. Mosley maintains his stance on its potential benefits, advocating for further research to elucidate its effects comprehensively. He emphasizes the importance of considering various factors such as meal timing and dietary composition in crafting optimal dietary strategies for health and well-being.
