Is obesity the next step in evolution through brain changes?

Obesity is a disease of complex and multifactorial nature characterized by the interplay of genetic and environmental factors. The prevailing consensus suggests that obesity arises from an imbalance in energy homeostasis, largely driven by excessive consumption of a high-caloric diet and insufficient physical activity. Over time, therapeutic interventions have traditionally focused on addressing this energy imbalance, as well as the medicalization of all types of obesity. However, there is an alarming increase in the prevalence of obesity, reaching pandemic proportions, with significant consequences for the health of a substantial part of the global population, undoubtedly necessitating a change in strategy.
