The Evolutionary Roots of Obesity
Human bodies are evolutionarily conditioned to gain weight, which can be traced back to survival mechanisms established during the hunter-gatherer era. The thrifty gene hypothesis explains that our ancestors stored calories to survive uncertain food environments, and while this was crucial for survival, it poses challenges in today's food-abundant society. Modern lifestyles, marked by easy access to large portions of calorie-rich and nutrient-poor foods, contribute to a phenomenon referred to as an obesogenic environment. As a result, many individuals find it increasingly difficult to manage their weight due to the outdated biological responses that urge them to store calories rather than expend energy.
