Natural Compounds Exert Anti-Obesity Effects by Regulating Cytokines

Obesity, along with its associated health risks such as hypertension, hyperlipidemia, Type 2 diabetes, stroke, metabolic syndrome, asthma, and cancer, constitutes a significant global health burden, contributing substantially to morbidity and mortality. Cytokines, a group of secreted signaling proteins, are crucial in initiating, maintaining, and resolving immune and metabolic responses. Although cytokines have unique advantages in regulating immune and metabolic functions, their therapeutic application for obesity remains limited in clinical practice. Natural compounds, known for their structural diversity and low toxicity, have become a valuable resource for drug development. Many natural compounds have shown anti-obesity effects. This review comprehensively examines the mechanisms underlying obesity, with a specific focus on the roles of cytokines, such as inflammatory cytokines, adipokines, and growth factors. Additionally, it highlights the regulatory interactions between gut microbiota and cytokines in obesity. The review critically analyzes current anti-obesity pharmacological interventions and summarizes advanced methodologies for identifying potential natural compounds. Finally, it identifies promising natural compounds that modulate cytokine activity to prevent or treat obesity and assesses their potential as complementary or alternative therapies.
