Despite the ubiquitous ‘obesogenic’ food environment, not everyone is overweight. Genetic susceptibility to the environment is thought to explain some of the individual differences in weight, with differential appetitive responses to food, being implicated as the mediating mechanism, so-called ‘Behavioural Susceptibility Theory’ (BST). BST hypothesises that individuals who inherit a more avid appetite, and lower sensitivity to satiety, are more likely to overeat in response to the modern food environment and to gain excessive weight – i.e. ‘obesity genes’ influence adiposity partly through appetitive mechanisms. This talk summarises the role of differential susceptibility to the environment in the obesity epidemic.
