Rates of obesity continue to increase in every country worldwide, and over 40% of adults and 19% of children in the U.S. now have obesity. This is a global crisis not only because obesity causes premature death and serious health problems, including diabetes, cardiovascular disease, and stroke, but also because obesity is an underlying driver of an even broader set of societal problems, including high rates of disability, inefficiency and absenteeism in the workforce, rising health care costs, stigmatization, and bullying.

Why Tufts?

Tufts has over 40 faculty members at the university and medical center, along with graduate students, who are conducting obesity research from basic science to societal solutions. In particular, our strengths in intervention research, biomedical sciences, active citizenship, and global connections are components that Tufts uniquely offers and are critical to building an innovative obesity collaborative. Together, Tufts University and Tufts Medical Center, with their strengths in obstetrics, pediatrics, and obesity treatment, play a central role in preventing and reversing obesity to create a healthier, more productive population with important benefits for local communities, global economies, and planetary health. 


TIGOR conducts cutting-edge research to inform and scale effective interventions to reduce obesity in the US and worldwide. Out work will advance health equity for all and provide outstanding training for the next generation of researchers.


TIGOR envisions a world where high impact discoveries in obesity research drive new solutions to improve health outcomes and health equity across the lifespan in the US and across the globe. 


TIGOR places utmost importance on diversity and inclusion. TIGOR promotes avoidance of weight bias and stigmatization, including through use of appropriate, sensitive, and respectful language and images.
