I'm a bit biased - I don't believe in fasting that much. Cutting back the splurges and luxuries, sure, but it is not healthy to fast like that. (Sorry - I'm a nurse - Catholic - had to say it)
If you insist on the fasting, I would make sure your meal is consisting of good complex carbs, protein, and some fat. All things that will help support your body and help avoid it from going into starvation mode. Think things like brown rice, beans, starchy veggies, lean meats, olive oil, avocado, nuts, eggs, lowfat dairy. Avoid anything refined and white. Since you're not eating during the day, you want your solid foods to be unrefined, to help keep your blood sugar stable.
When are you doing your workouts? I hope in the evenings, so you can eat right after to help recover your muscles. If you are getting light-headed, shaky, and suddenly nauseated, your blood sugar is probably too low - drink some chocolate milk (sugar for a quick rise, protein to stablize). If this happens frequently, you may need to eat some snacks during the day. I understand the religious side of the fasting, but I don't think God wants us to land in the hospital for passing out.
