This episode explores the psychological and behavioral factors that impact healthy eating and why willpower alone is insufficient for lasting change.

In today’s episode of Bite Back with Abbey Sharp, we unpack why knowing how to eat “healthy” doesn’t always translate into actually doing it. We explore the science of behaviour change, why willpower and motivation alone aren’t enough, and the many biological, psychological, social, and environmental factors shaping our food choices.
