Cochrane Review Questions Intermittent Fasting Efficacy

A new Cochrane review, led by Luis Garegnani and Eva Madrid, analyzed 22 clinical trials involving nearly 2,000 adults and found that intermittent fasting does not lead to significantly greater weight loss than traditional dietary advice or no intervention. The review challenges the widespread belief in the effectiveness of intermittent fasting, which has gained popularity through social media. Experts like Jörg Meerpohl and Stefan Kabisch noted the uncertainty of the evidence due to varied methods and short-term studies. The World Health Organization's data highlights the global obesity crisis, underscoring the importance of effective weight management strategies. The authors caution against extrapolating results to the entire population and recommend a case-by-case approach for doctors.
