It has been demonstrated that not only the components of food are important, but quantity and quality are also crucial elements of a healthy eating pattern. Chrononutrition is an emerging tool that could help improve dietary interventions beyond those derived from consuming an adequate amount of each nutrient. Diabetes is a complex endocrine pathology characterized by sustained hyperglycemia. Dietary changes are a key component in obtaining adequate control and preventing long-term complications. Recent studies emphasize the use of chrononutrition and its components as a novel dietary intervention that could improve metabolic control. The use of chrononutrition as a dietary intervention is faced with challenges such as the presence of gaps in the literature that limit its implementation.

Adipose tissue (AT), primarily composed of adipocytes, stores substantial amounts of energy and plays a crucial role in maintaining whole-body glucose and lipid metabolism. This helps prevent excessive body fat accumulation and lipotoxicity in peripheral tissues. In addition, AT contains endothelial cells and a substantial population of immune cells (constituting 60-70% of non-adipocyte cells), including macrophages, T and B lymphocytes, and natural killer cells. These resident immune cells engage in crosstalk with adipocytes, contributing to the maintenance of metabolic and immune homeostasis in AT. An exacerbated inflammatory response or inadequate immune resolution can lead to chronic systemic low-grade inflammation, triggering the development of metabolic alterations and the onset of chronic diseases. This review aims to elucidate the regulatory mechanisms through which immune cells influence AT function and energy homeostasis. We also focus on the interactions and functional dynamics of immune cell populations, highlighting their role in maintaining the delicate balance between metabolic health and obesity-related inflammation. Finally, understanding immunometabolism is crucial for unraveling the pathogenesis of metabolic diseases and developing targeted immunotherapeutic strategies. These strategies may offer innovative avenues in the rapidly evolving field of immunometabolism.
