Obesity can seem straightforward to explain. If a person consumes more calories than they need, they gain weight. But the real explanation is not that simple. And it is about more than weight.
Obesity is a complex chronic disease, and losing weight is not just a question of eating less and moving more. In fact, obesity can be influenced by genetics, physiology, environment, job and education, and what is going on in the brain.
Understanding these factors is critical, because obesity is associated with other diseases, including type 2 diabetes, heart disease and certain types of cancer. Not to mention the stigma and bias millions suffer every day.
But with the right care, people with obesity can achieve sustained weight loss that really makes a difference to their health.
Today we know that obesity is a serious chronic disease, not simply a matter of effort.
Together with our partners, we are committed to driving change in how the world sees, prevents and treats obesity. As leaders within the science of obesity, we are working to make obesity a healthcare priority, defeat stigma and support better access to evidence-based care.
