Do a search for the nutritional qualities of Fennel for specific dietary concerns or even consult with a physician for any concerns.

Note at the bottom of the article that Fennel is an exception. It doesn't get along with others!
I also might suggest contacting a local grocery store in you area about the nutritional qualities of Fennel that you are wanting more specifics about. I know that many of the local grocery stores in my area employ a qualified nutrition expert that is available for questions and consultations and provide specific calorie and nutrition information.
I myself plant Fennel in my flower garden and keep it out of my herb bed.
