Main areas of interest include the physiology and pathophysiology of energy and substrate metabolism, with special emphasis on the etiology and treatment of obesity.
Major current research is focused on the role of dietary macronutrients and glycemic index for body weight regulation, and the hormonal mediation of hunger and satiety by gastrointestinal peptides such as GLP-1, PYY, CCK etc.. In addition, I head the OPUS Centre, 'Optimal well-being, development and health for Danish children through a healthy New Nordic Diet’, which runs from 2009 until 2013. The main objective is to develop a healthy and palatable new food and eating concept, and to examine how such a diet can affect mental and physical health in a Nordic population.
