A groundbreaking international study spearheaded by researchers at the University of Granada has unveiled a promising therapeutic avenue for addressing muscle deterioration caused by obesity and type 2 diabetes, collectively known as "diabesity". The research demonstrates that melatonin, traditionally recognized for its role in regulating sleep patterns, can significantly enhance muscle health. By altering the composition of muscle fibers, melatonin improves mitochondrial function, reduces cellular stress, and prevents programmed cell death. These findings suggest a novel approach to managing metabolic diseases.

Professor Ahmad Agil, leading the pharmacology department at the University of Granada, highlights how melatonin administration over 12 weeks transformed glycolytic (fast) muscle fibers into oxidative (slow) ones in obese and diabetic rodents. This transformation boosts energy efficiency and shields muscles from the adverse effects of diabesity. Muscles with higher proportions of oxidative fibers are better equipped to burn fat and produce energy efficiently. Moreover, melatonin mimics the benefits of prolonged aerobic exercise by enhancing mitochondrial function and maintaining calcium balance within cells, thereby reducing cellular stress and preventing cell damage.

The potential implications of this research are vast. With nearly 900 million people affected by obesity and 800 million by type 2 diabetes globally, the development of an accessible and effective therapy based on melatonin could revolutionize treatment strategies. The study's results, published in reputable scientific journals, provide a strong foundation for further clinical trials in humans. If successful, this innovative treatment could not only improve muscle health but also enhance the overall quality of life for millions suffering from these conditions. Emphasizing the importance of a balanced lifestyle, including regular physical activity and proper rest, remains crucial in maintaining muscle health and preventing metabolic disorders.
