Durante anos, o jejum intermitente foi apresentado como uma revolução metabólica — uma forma de enganar o corpo e perder peso com mais eficiência do que qualquer dieta convencional. Um novo estudo do Centro Cochrane, que analisou quase dois mil participantes em ensaios clínicos, vem agora relativizar essa promessa: o jejum intermitente funciona, mas não melhor do que outras abordagens alimentares. A ciência, mais uma vez, convida à humildade diante das modas e reconduz a atenção ao que resiste ao tempo — movimento regular e nutrição consciente.

Consumers may reduce spending on intermittent fasting-specific programs, apps, and supplements, redirecting discretionary health spending toward traditional diet approaches. Reduced demand for premium fasting-focused wellness services and products.

May prompt stricter advertising standards for weight-loss products and dietary interventions. Health authorities may revise nutritional guidance to reflect evidence-based findings rather than trend-driven recommendations.
