To understand the obesity epidemic we need to understand when it started and what happened at that time. After a few million years of evolution, did we wake up one morning and decide to eat too much and do too little? Public health authorities imply that we did; but we didn't. Something did happen, however, and it involved those same public health advisors. In this presentation, Zoë takes us through what changed, why it made a difference and what we need to do to stop the relentless rise in obesity and related illness. There is a solution, but those who should be leading the way aren't doing so. Why not? And what can we do as participants in the bottom-up revolution?
