What really happens when you stop dieting and start eating healthy? In this episode, we hear from two real people who spent years trying to “do the right thing” with food and still felt stuck. 
Today, we’re joined by Becky and Mark, two ZOE members sharing their personal journeys. Each of them has spent the past two years consistently applying ZOE nutrition principles. Instead of relying on rules or restrictions, they embarked on a science-led journey with ZOE, focused on understanding their bodies. The results? Truly remarkable - ZOE became such an important part of their lives that, alongside 18,000 other members of our community, they became ZOE owners through our crowdfunding. So what changed, and did it last?
Alongside Professors Tim Spector and Sarah Berry, we explore how Becky and Mark stay motivated and on track, the lessons they have learned, and the strategies they have used to feel more in control and more confident in their everyday choices. As well as some unexpected shifts along the way.
It’s a conversation about long-term change, not quick fixes, and you’ll leave it with real-life examples of how to make healthy eating a part of your everyday life.
If healthy eating wasn’t about willpower or perfection, what small change would you start with? And what would help you take that first step this week?
