Today's podcast includes the conclusion of Dr Angelo Tremblay's recent lecture on ways to prevent obesity in 2011 and beyond. In this section he focuses on the role of "preventive" pharmacology, most notably Ritalin, as well as taking a number of fascinating questions from the researchers and health professionals in the audience.
