I've been through the audio for level I and II several times. There is some food advice in there. However, is it just sprinkled here and there as I suspect it is in the courses.
As for fasting there is lots of information on the web, and in books. Master Lin only just touches on the topic in the level III material. The materials sounds fine, until you serious think about actually using it to fast. Then you start digging into the details. You can search the forum for some information on fasting.
You are perfection.
