Summary: The aim of this Chair program was to document environmental influences on energy balance. The program aimed to identify and describe the impact of non-traditional environmental factors on the balance between energy intake and expenditure. It therefore had great potential for scientific innovation and public benefit.

Main spin-offs: The contribution of Professor Tremblay’s Chair has been noted in many spheres of public and scientific life. It has highlighted the fact that a positive energy balance can be induced by factors traditionally little considered. The scientific program took shape in the form of publications and conferences at national and international level. In addition to scientific dissemination, the Chair has led to a commitment to student training, closer links with industry and government agencies, and dissemination to the general public. It has contributed positively to the reputation of Université Laval, and has left a significant legacy for young researchers, healthcare professionals and the general public.
