We live in an 'obesogenic environment' where we are constantly bombarded with choices that encourage us to move less and eat more. Many factors influence our dietary choices, including the expert marketers who advise manufacturers on ways to encourage the population to buy more, especially profitable, palatable 'ultra-processed' foods. Supermarkets themselves have become skilled in manipulating buying behaviour, using their layout and specific product placement as well as advertising to maximise purchases of particular foods. Increasingly, supermarkets push their own 'house' brands. Those marketing fast foods also use persuasive tactics to attract customers, especially children who they entice with non-food items such as promotional or collectable toys. There is no mystery to the increase in obesity: our energy intake from foods and drinks has increased over the same period that energy output has decreased. Obesity has a range of relevant factors, but there is little doubt that marketing from supermarkets and fast food retailers has played a role.
