Why do some people feel fine eating lots of carbs when others feel energy slumps? Is blood sugar to blame?

In this episode, we learn why blood sugar varies so much between people, and the tools to manage these levels.

Tim Spector and Jessie Inchauspé (aka the Glucose Goddess) will discuss the latest science around glucose control, what the cool new device on the block – the CGM – can tell us and why blood sugar levels are only one part of the picture of our health.

Jessie is a bestselling author and science communicator with a community of over 5 million followers. Tim is a professor of epidemiology at King’s College London and ZOE’s scientific co-founder.
