Obesity is arguably the most important public health issue of the 21st century. Irrespective of the environmental, genetic or dietary driver, an inability to match energy and nutrient intake to energy expenditure and nutrient needs is the primary cause of weight gain.

In particular, the role of combinations of food ingredients will be the focus of this project.
