Although it is a multifactorial disease, there is strong evidence of the influence of advertising and the obesogenic environment in changing dietary habits. Industry/commerce food techniques can generate excessive consumption by developing flavors, images and techniques of persuasion, and by the production of foods high in sugar, salt and fat which are rewarding nutrients.

It also discusses the transtheoretical model as a tool for intervention in the treatment of obesity.
