Interview With Franziska Spritzler on the 2014 LCC

FranziskaFranziska Spiztler is one of those truly rare individuals who went through the effort and training required to become a registered dietician, and then discovered that what she was taught was mostly wrong. She had the courage and the integrity to challenge the system.

Franziska and her husband, Mark, were among our tablemates for dinner on the 2014 LCC cruise. When I learned that she was a registered dietician who bucked the system and went low-carb, I immediately asked her if she was willing to do a video interview, and she agreed.

Mark turned out to be a techie like me, with a background chock full of video work, and he volunteered to help with the camera. You will probably notice that the video quality is better on this interview than on some of the others, thanks to Mark. And also thanks to the time of day (more natural light).

We had a really nice chat (despite an interruption by our room steward), with occasional off-camera comments by Georgene & Mark.
