Global Energy Balance Network

The Global Energy Balance Network (GEBN) was a US-based nonprofit organization claiming to fund research into causes of obesity, but was primarily known for promoting the idea that lack of physical exercise, not bad diet, was primarily responsible for the obesity epidemic. It has been characterised as an astroturfing organisation. It received substantial funding from Coca-Cola. It has been criticised by nutrition experts for downplaying the role of junk food in obesity. Critics have also accused the American College of Sports Medicine (ACSM) of supporting GEBN. The ACSM claims it had no affiliation with GEBN.

GEBN's view of weight and metabolic health promoted the idea that weight loss can be achieved by taking more exercise while maintaining the same level of consumption - this view "crosses a line by advancing a view that falls outside the scientific consensus", and presents an overly simplistic view of the energy balance equation, with experts noting that "evidence for eating less as a weight-loss strategy is much, much stronger than the evidence for moving more".
