If you haven't seen the documentary Fat Fiction, I highly recommend that you watch it. It's a well-made, professionally produced film about how the U.S. dietary guidelines created an atmosphere that undoubtedly contributed to our current crisis of obesity and type 2 diabetes.

But the film also shows us what we can do about it. It provides a message of hope as it follows low-carb doctors and nutritionists, showing how they impact the lives of their patients.

Documentaries about nutrition are challenging to pull off. The director's decisions are critical: How much detail should be included on each topic? How much science should be highlighted? How much time should be spent on inspirational stories? And how should the film's point of view be balanced?

Jen and I discuss these topics and more in this engaging interview.
