Prof. Alexandra Johnstone is recognized as a leading innovative UK researcher within the field of human appetite control and specifically, the role of dietary protein. She is a Professor at The Rowett Institute at the University of Aberdeen in Scotland.

In This Episode We Discuss

  • Common foods in our food system = not ideal for controlling appetite.
  • Thinking about overall diets vs. single nutrients
  • Bottom-up & Top-down interventions for impacting satiety & caloric intake
  • Is it possible to make population-wide changes to alter average caloric intake?
  • The use of ‘nudging’ to make population shifts in diet choices
