Don't worry about minor details like fat in your oat bran. Just don't add extra butter to it. Superfood is fine before the flush. When you're super congested these details don't matter anymore because the stones will come out no matter what.
If your colon is clogged then you may not see stones come out at all but you will feel very gassy. That means that the stones are somewhere in the intestines. Take a dose of epsom salt in the morning and do a clear water enema. Follow with coffee enema but only 2 cups, not more!
Don't forget to start a colon cleanse!
