abstract
The incidence of obesity worldwide has become a serious, constantly growing public health issue that reaches alarming proportions in some countries. To date none of the strategies developed to combat obesity have proved to be decisive, and hence there is an urgent need to address the problem with new approaches. Today, studies in the field of chronobiology have shown that our physiology continually adapts itself to the cyclical changes in the environment, regardless of whether they are daily or seasonal. This is possible thanks to the existence of a biological clock in our hypothalamus which regulates the expression and/or activity of enzymes and hormones involved in regulating our metabolism, as well as all the homeostatic functions. It has been observed that this clock can be upset as a result of today%27s modern lifestyle, which involves a drop in physical activity during the day and the abundant ingestion of food during the night, among other factors, which together promote metabolic syndrome and obesity. Hence, the aim of this review is to summarise the recent findings that show the effect that altering the circadian rhythms has on the metabolism and how this can play a part in the development of metabolic diseases.
