On general advice I think start with raw fruits and vegetables
for one day per three days you have fasted(40 days on juice then 13 days on raw). After that, resume to healthy cooked foods... Do not insist with foods or quantities that upset you. Your body might/should tell you when to break your fast, what foods to eat and how much to eat.
I would continue fasting as long as I am not hungry if I were you...
Good luck.
