Nursing is a health discipline built on philosophy, theory, application, and research. The use of models in nursing allows nurses to focus on the role of nursing and its applications rather than on medical practice. In addition, the use of models allows patient care to be systematic, purposeful, controlled, and effective. The Roy Adaptation Model is a model commonly used in nursing to create a structure under which the needs of individual humans, families, and groups can be determined; the model focuses on an adaptive system of human and environmental alterations. It includes four areas of adaptation: physiological, the self-esteem concept, role function, and dependance on mutual areas. In this model, “human” is portrayed as a biopsychosocial creation of an interactive and affective environment. Nurses not only take care of the health needs of obese individuals but are also the responsible health professionals to ensure that such individuals adapting to the difficulties they face. This study aims to create awareness about the Roy Adaptation Model’s use in nursing practice, emphasizing that it provides guidance for obesity care and helps to enlighten discipline-specific studies.
