The research area of nonobese patients focuses on studying individuals who do not fall into the category of obesity, typically defined as having a body mass index (BMI) of 30 or higher. Researchers in this area may investigate various aspects of health and wellness in nonobese individuals, such as metabolic health, cardiovascular risk factors, dietary habits, and physical activity levels. By studying nonobese patients, researchers aim to better understand the factors that contribute to overall health and potentially identify strategies for preventing and managing chronic diseases in this population.
