Since 1980, the number of people around the world with type 2 diabetes has quadrupled. Kidney specialist Dr Jason Fung joins Liz for this episode of the podcast to cover the rise in obesity and type 2 diabetes - and what can be done about it.

In this episode, Jason explains how dietary interventions such as intermittent fasting or low-carb eating may be able to reverse the dietary disease, plus why all calories aren't equal.

Liz and Jason discuss how we can avoid spiking our blood sugars, how hormones such as cortisol and insulin can cause weight gain, and why fats shouldn't be considered the enemy when it comes to eating well.
