Melatonin plays an essential role in the management of obesity, partly because of its ability to increase the body's thermogenic capacity. We tell you how supplementation with this hormone can help the weight loss process. Obesity can be defined as a generalised excess of body fat that responds to a positive energy balance whose origin is located in a multifactorial and complex network related to the physical, psychological and social sphere of the human being. Do you know what the role of melatonin is in the management of obesity? Most of those who suffer from obesity suffer from what is known as chronodisruption, an internal imbalance whose maximum representative is sleep disorders and which does nothing more than help them to continue accumulating body fat. Thus, it seems that improving the quality of sleep is fundamental and melatonin plays an essential role in this. - Sleep and obesity Sleep is an essential process for restoring cellular energy stores and restoring homeostasis of the central nervous system and other body tissues. Both tasks are fundamental to ensure the correct functioning of the organism and, therefore, to maintain an adequate body composition. In this sense, it is known that most people suffering from obesity go to bed late and do not achieve a good night's sleep. This makes them tired during the day and, as a consequence of their lack of energy, they eat more - to get energy - and move less - to save energy. The body needs energy to carry out its vital functions. When it has not obtained enough through sleep, it leads us to eat more and move less.
