Obesity is a chronic disease that affects over 764 million adults worldwide.1 It has a substantial health impact with 200+ possible complications affecting many organs and systems.2,3 As a result, healthcare professionals (HCPs) see patients with obesity throughout their clinical practice and widely recognise it as a serious, chronic disease that often relapses.4 Yet, the number of people living with obesity continues to rise, highlighting the need to provide medical professionals with evidence-based tools to tackle the growing global obesity epidemic effectively.

The science to obesity

By understanding the scientific principles that underlie the development of obesity and identifying challenges in an evidence-based manner, barriers to effective obesity management can be overcome. Rethink Obesity® aims to provide this science based information, in an easily accessible manner, to healthcare professionals so they are able to enhance their clinical practice and achieve sustainable results for their patients living with obesity.
