Obesity has reached epidemic proportions globally, with more than 1 billion adults overweight - at least 300 million of them clinically obese - and is a major contributor to the global burden of chronic disease and disability. The obesity epidemic is not restricted to industrialized societies; this increase is often faster in developing countries than in the developed world. In order to participate to slow down and stop the progression of this disease, Riga Diabetes & Obesity 2015 will discuss the latest therapeutic innovations, the new pathways which will allow the development of new pharmaceutical treatments but also discuss how to prevent diabetes and obesity by using natural ingredients. Riga Diabetes & Obesity 2015 aims also to launch the discussion between the different actors involved in the fight against obesity. It still remains that diabetes and obesity are multi-factorial problems, involving genetic, neurological, behavioral and cultural components, and as such, a long term solution to the problem is unachievable through single sector approach. Instead an integrated strategy is required, with input and close collaboration from all of the many different stakeholders involved - the food industry, governments and regulators, researchers, health professionals, the media, and of course consumers themselves.
