Men's health has often been overlooked in health care, with traditional gender norms and societal expectations significantly shaping men's health behaviors and attitudes. The MANifest Health Theory (MHT) offers a comprehensive framework to address cis-gender men's unique health needs by considering the complex interplay of biological, psychological, and social factors. Rooted in four interconnected core concepts-Biopsychosocial Model, Health Optimization, Health Synchronicity, and Ethnocultural Expression-MHT provides a holistic understanding of men's health. This article explores how MHT integrates inductive and deductive reasoning, describing, explaining, predicting, and controlling aspects of men's health. Key components such as Gender-Sensitive Care, Health Empowerment, Supportive Environments, and Interdisciplinary Collaboration are discussed in relation to practical strategies for health care delivery. The limitations of MHT, including its developmental status, cultural applicability, and inclusivity of diverse gender identities, are acknowledged. Future steps for validating and refining the theory through empirical research, cultural adaptation, and inclusion of diverse gender experiences are outlined. By applying MHT, health care professionals can deliver more holistic and culturally competent care, promoting healthier lifestyles and reducing health care disparities among men.
