Gourmand savants and environmental determinants of obesity.
Obesity is an embodiment of a multifactorial problem with several intermediates in its casual pathway. Virtually all who have written on obesity have responded to four inter-related factors: genetic, perinatal, environmental, and consumption-expenditure energy imbalance. The message to take home is that while a molecular description of each participant of the obesity machinery seems achievable in principle, a complex model describing all of them is currently beyond our grasp. That is why the eradication of the obesity epidemic is seen in a more precise neuropsychological description of what is wrong with each subset of patients. This review proposes that the neuropsychiatric experience might be the most fundamental for it could help to refocus the view of obesity from 'traditional' environmental factors and lifestyle changes to those dominated by a more 'individual-centred' perspective in which different modes of causal attribution are appropriate. This review advocates the idea of environmental dependency as a determinant of obesity, which has been an important idea in neurosciences for more than 30 years with roots in three important areas: psychological, neuropsychiatric, and experimental. The neuropsychology of obesity is yet to become part of today's agenda of obesity research.
