Remember, you will add some back to your colon and take on some water, so ending and stabilizing isn't an effective idea. Get to a holistic doctor or someone who is accepting of fasting and get your body mass index and fat percentages done correctly. After that, set your targets based on those numbers and juice fast off the fast, add high quality nutient dense foods and monitor your percentage of body fat, give yourself an acceptable range (like "I can add 2% body fat before I react) and keep working your diet/exercise regiem until you get a good balance.
Congrats!
