Resolution of this issue is epidemic affecting not only North America, important to prevention and treatment. Can obesity be but also many other developed and avoided by the rigorous daily activity and limited availability of food found in many hunter-gatherer developing nations (GBD 2013 Obesity groups, or is the accumulation of body fat an inevitable Collaboration, 2014; World Health consequence of the human genome?

Perhaps as a narrative review has gathered available information on eating habits, habitual daily physical activity and body fat consequence of this attention, we tend to accumulation over various historical eras, ranging from regard an excessive accumulation of body the earliest Paleolithic and Neolithic communities to fat as a modern problem, brought about by Victorian society. Results: The success of Paleolithic and Neolithic communities generally depended upon high a combination of over-eating in response levels of daily energy expenditure, and despite the to the wiles of giant commercial food discovery of some obese "Mother Goddess" figurines, distributors, intent to increase our studies of small communities that have maintained a Neolithic lifestyle still show very low levels of body fat. consumption of their products, by With the development of settled societies based upon an industrial automation with ever more agricultural economy, an economic surplus and social sedentary work, and by a progressive stratification allowed the emergence of a growing upper echelon of society that could over-eat and engaged in too reduction of daily energy expenditures in little physical activity. However, the widespread our leisure time. prevalence of obesity across developed societies is a late In exploring the lifestyle of successive 20th century phenomenon, associated with ever- decreasing needs for energy expenditure in daily life, cultures from the Paleolithic world reduced opportunities for deliberate leisure activity in through to Victorian times, this historical mega-cities, the promotion of over-eating and unhealthy review in general supports the thesis that diets by commercial interests, and possibly a greater public acceptance of obesity. Conclusions: Obesity is obesity was the exception rather than the typically an expression of over-eating and inadequate rule during most of antiquity. habitual physical activity.
