Hi Bill...welcome to the forum.
If you Google "Intermittent Fasting" you will find a ton of articles and studies on the science behind IF.
If you are looking for some ideas on implementing IF, some posters on the CrossFit forum have shared their experiences with IF:

The search function will reveal all.
Art DeVany sometimes touches on IF in his blog:
