Abstract
Traditional treatment strategies and public health interventions aimed at reducing the incidence of obesity are proving inadequate at controlling the global epidemic of this condition. The main focus of any intervention should be on preventing small excesses of weight, which lead to large weight gain over time, as once a large amount of excess weight is gained, it is very difficult to lose. The only effective approach is for governments to implement radical policy change, to regulate food consumption and control the food industry in a similar way to that of the tobacco industry, by banning the advertising of selected produce, taxing certain foods, and rationing the purchase of others.
