Why do so many of us eat a "healthy" breakfast like cereal or muesli, only to feel hungry, tired, and foggy by 11 AM? And why is it so hard to break this routine, even when we know it’s not working?

In this episode, Jonathan Wolf speaks to Professor Ben Gardner, a leading expert in habit psychology, and Professor Tim Spector, a world-leading scientist in nutrition and gut health. 

They explore the science behind why our breakfast routines are broken, how they set us up for a daily blood sugar rollercoaster, and what to do to fix things. 

Tim breaks down the latest science on common breakfast foods, explaining why most cereals, muesli, fruit juices, and "high-protein" options are failing us, leading to energy dips and mood changes.

Ben explains the psychology of why we're stuck. He reveals why bad habits run on autopilot, why our environment is more powerful than our willpower, and busts the persistent "21-day" myth, explaining how long it really takes to form a new habit.
