A recent systematic review published in the Cochrane Library provides a significant insight into popular dietary trends, particularly regarding intermittent fasting (IF). Despite its rising popularity as a weight-loss strategy touted extensively on social media, the review indicates that IF does not provide superior results compared to traditional calorie-restricted diets. This finding is particularly relevant for the adult population in Spain, where obesity is a pressing concern affecting over half of adults.

The researchers, led by Luis Garegnani from the University Institute of Dietetics, assessed a wealth of studies comparing IF with standard caloric restriction regimes. The review establishes that while IF can indeed result in weight loss, it does not outperform conventional diets that focus on reducing caloric intake. This contradicts the widespread perception that intermittent fasting could be a revolutionary approach for weight management, suggesting that more traditional methods may still hold significant weight.

Considering the public enthusiasm surrounding intermittent fasting, this review aims to offer a grounded perspective on dietary choices. It emphasizes the importance of evaluating weight-loss strategies critically, particularly when combating issues like obesity that are prevalent in Spain and many other regions. The findings encourage individuals to consider conventional dieting as an equally viable or potentially more effective means of weight management, rather than being swayed solely by the latest dietary trends.
