The Maker's Diet Revolution by Jordan Rubin sounds interesting. It is primarily a fast to grow closer to God and is only for ten days, but it also takes weight off. He calls it a Daniel Diet and recommends reading about Daniel when he was asked to eat rich fools in the first chapters of Daniel.
Get up early enough to drink 8 glasses of water by 12:30, spacing them by two glasses at a time.
At 12:30 have some fruit and fats. Fats should come from Avocado, coconut, nuts, or seed, preferable soaked first.
At 3:30 have veggies and some fat from the above source. No processed dressing, but it suggests a sort of guacamole made of avocado, onions, lemon juice, tomatoes in a blender.
At 6:30 repeat the raw fruit with healthy fat listed above.
You are to have four more glasses of water between meals in the afternoon.
Just as Daniel did, you are to set aside time devoted just to prayer. I use a prayer shawl to shut out the world around me and just listen to the Lord. Daniel prayed at 9:00 AM, noon, and 3:00. Evening prayer is at 6:00. Studying these times that seem to be actual times that God grows close is in interesting bible study. Even the crucifixion of Jesus follows these times.
