CARRIE - I hope you see this thread. To answer your question, a professional fasting coach usually recommends that if you are active you should continue that activity during a fast and if you are not active you should become active.
Before I considered water fasting, I read about it for almost a year. Most of the things I assumed about fasting were entirely wrong. We are bombarded with the belief we need to eat, eat, eat. Yet fasting is what animals naturally do to deal with many if not most of their illnesses.
I did a water fast for 13 days after Thanksgiving and my energy level went up, a good deal more too than when I ate raw. This has nothing to do with the type of food you eat but because you aren't eating. Up to 60% of our energy is used for digestion. The first few days of the fast reminded me of the first few days on a Master Cleanse and it is an adjustment to not eat but it isn't due to hunger but that so much of our socializing is centered around food and drink and we are just accustomed to doing it.
If you want something other than a continuation of fasting myths, go to FastingConnection.com. There is a medical doctor who has supervised over 10,000 fasts at his clinic in Johannesburg who visits the site daily and often answers most medical questions. He has been fasting for over 30 years and is also a high raw vegan (but does eat eggs and cream to assist with switching over to a catabolic state before a fast). People there are also keeping blogs regarding their fasts and you can see their triumphs as well as their struggles. It is a great site for those interested in the topic.
