You can put a label on the body's problems, but the basic problem is that it is out of balance.
In order to bring it back into balance and health, various cleansings need to be done, but done in a particular order so that you have the least distress and the greatest success.
Thus, the bowel cleansings are first, I believe; if you wish to do liver flushes and the parasite cleanses, then you will need to do a kidney cleanse so that your kidneys can handle all of the toxins being removed from the body.
The oranges allow you to be nourished while doing the fast; it makes it easier than doing a water fast. You really should buy MH's first medical book which explains how the one cure cures all. You need to understand the processes if you wish to do these kinds of cleansings; knowledge is key to your success.
#19236 just finished a very successful 40-day fast; I believe it is on Pages 20 or 21 of the forum -- it is worth your reading.
In the meantime, reread MH's booklet several times; each time, you will discover something that you missed on the first reading!
Once you have 'your ducks in order', then you'll be ready to move forward.
