Metabolic diseases, like obesity, type 2 diabetes, and cardiovascular issues, are a global epidemic, bearing substantial health and economic burdens. Regular exercise is emerging as a key preventive and management tool for these conditions. It enhances insulin sensitivity, reducing the risk of insulin resistance and type 2 diabetes, promotes weight loss and maintenance, and provides cardio protective effects by improving lipid profiles, blood pressure, and reducing inflammation. Recent research has uncovered the molecular mechanisms behind these benefits, involving various signaling pathways and myokines. Tailored exercise prescriptions, combining aerobic and resistance training, can significantly improve metabolic parameters, when integrated with pharmacological and dietary approaches for a multidisciplinary approach.
