Abstract

This paper delves into the evolving landscape of modern nutritional trends, with a primary focus on intermittent fasting (IF) and its various adaptations. Intermittent fasting has gained substantial popularity due to its potential benefits for weight management, metabolic health, and longevity. This review examines the scientific evidence behind different IF protocols, including time-restricted feeding, alternate-day fasting, and the 5:2 diet, highlighting their physiological and psychological impacts. Furthermore, the paper explores other contemporary dietary trends such as ketogenic diets, plant-based eating, and personalized nutrition. By analyzing the efficacy, safety, and long-term sustainability of these dietary patterns, the paper aims to provide a comprehensive understanding of how modern nutritional trends can contribute to improved health outcomes. The discussion includes potential risks, benefits, and practical considerations, offering insights for healthcare professionals, dietitians, and individuals seeking to optimize their dietary habits in a scientifically informed manner.
