Keto has been promoted as a magic bullet for weight loss by its supporters and slammed as dangerous by its opponents. It's no surprise - completely removing almost all carbohydrates is not what most people consider ‘a balanced diet’.

With carbs off the table, Keto diets involve a dramatically increased fat intake. At the same time, drastically reducing carbs means starving our gut microbes of the fiber that feeds them.

Nonetheless, doctors prescribe keto diets to treat people with severe diabetes and see dramatic improvements, and many healthy people swear by keto for weight loss. On top of this, removing carbohydrates prevents blood sugar spikes and crashes linked to inflammation and disease.

In today’s episode, Jonathan speaks to a leading nutritional researcher to understand whether or not keto diets are a crazy fad:

Christopher Gardner is a professor at Stanford University and a member of ZOE’s scientific advisory board who’s produced a clinical trial of keto diets, published in the American Journal of Clinical Nutrition.
