Abstract

The interplay between lifestyle behaviors and psychological traits has become an increasingly significant area of inquiry, particularly among emerging adults navigating academic, social, and physiological transitions. This study examines the multidimensional relationship between stress levels, dietary habits, exercise patterns, and underlying psychological constructs, including the Dark Triad personality traits and the concept of relative energy deficiency in sport (RED-S). Drawing upon a synthesis of contemporary literature, this research integrates perspectives from sports medicine, behavioral psychology, and public health to provide a comprehensive understanding of how lifestyle imbalances contribute to both physical and mental health outcomes. Evidence suggests that inadequate energy intake relative to expenditure, as conceptualized in RED-S, is associated with physiological dysfunctions and psychological disturbances. Concurrently, stress and maladaptive coping strategies are linked to unhealthy dietary patterns and reduced physical activity. The presence of Dark Triad traits further complicates these relationships by influencing behavioral tendencies, emotional regulation, and social interactions. The study critically evaluates theoretical frameworks, empirical findings, and methodological challenges, highlighting inconsistencies and gaps in current research. The findings underscore the need for integrative models that account for biological, psychological, and social determinants of health. This research contributes to the growing discourse on holistic well-being and emphasizes the importance of interdisciplinary approaches in addressing complex health challenges among young adults.
