Dr.'s orders, change in plans

As so many of you already know, I was diagnosed with Stage 0 (very early stage) colon cancer several years ago, and after a simple procedure, and some treatments, I have been cleared of cancer ever since.
This past June while in the hospital the Dr discovered my white cell count was extremely low, and felt that after finding out my gallbladder came out she felt that might have an effect on my cell count. Months passed and test after test have been done. Right before Christmas I under went a Plethora of blood tests, all which lead the Dr's to suspect the colon cancer MAY be back. In the meantime my Dr. has asked me to refrain from any homeopathic, herbal, or plant based products as they can sometimes alter any blood testing/screening. I wrote to John Anderson, the Master Formulator for Isagenix, and asked him if this was true, his reply was to follow the Dr's advice! So, as of this morning I had my last shake until I know what is actually going on.
This will not however change my plans for weight loss. I am after all in for the long haul, and entered into a weight loss challenge as one of my major goals, so I have to stick to some sort of plan.
I am choosing to go the high protein, low carb plan, lots of fruits and veggies, no white processed fours, only whole yummy wheat's, and lean meat (once in a while) chicken and fish!
I will continue with my daily journal, filing everyone in on my days, and what is going on as this helps me SO much, I just can not believe!
Have a great rest of the week.
