The August 26, 2011 issue of The Lancet is dedicated to the global obesity epidemic. The issue was timed to coincide with the upcoming United Nations high-level meeting concerning non-communicable diseases. The first high profile global meeting dedicated to obesity was sponsored by the World Economic Forum in 2004. Seven years later, the obesity epidemic is spreading to urban areas in developing countries.
Below is The Lancet's overview of its obesity issue
This four-part Series critically examines what we know about the global obesity pandemic: its drivers, its economic and health burden, the physiology behind weight control and maintenance, and what science tells us about the kind of actions that are needed to change our obesogenic environment and reverse the current tsunami of risk factors for chronic diseases in future generations.
The first paper looks at the global drivers of the epidemic; the second paper analyses obesity trends in the USA and UK, and their impact on prevalence of diseases and healthcare spending. The third paper introduces a new web-based bodyweight simulation model, that incorporates metabolic adaptations that occur with decreasing bodyweight; and the final paper assesses the interventions needed to halt and reverse the epidemic. Its authors conclude that the changes needed are likely to require many sustained interventions at several levels, but that national governments should take the lead.
