Basically the title. I am a 29 year old female and I have no health issues. I take iron pills, but no other medication.

The Holy Spirit has placed it on my heart to fast. There are many reasons why I would like to and was thinking of fasting (no food whatsoever) for 7 days. I am brainstorming some ideas for prayer for the fast and came up with some good ideas, I am focusing on the practicals.

I have some questions:

1. Should I start with a 24 hour fast, or should I just go ahead with the 7 days?
2. I am really overweight and have been trying to eat better and work out (has nothing to do with the reasons for this fast). Should I still work out during fasting, even if it is 24 hours of fasting?
3. What do you eat the day before your fast? And what do you eat after? Is it safe to eat after 7 days?
4. I heard some people do a bread and water fast. I think that might work for better for 7 days, but the supermarket bread in my country sucks. Anyone have any bread recipes or suggestions?

Complete newb at this. Any and all help is appreciated. God bless. ^^

Edit: Correction, I have fasted 24 hours before with bread in a Poustinia through the Madonna House.
