I thought your idea might not have merit until I started researching coffee online. I'm not sure whether coffee would provide any added benefit. Here is the link to the article. Scroll down to #9, Health and click on the link. It will take you to the section regarding the health benefits/non-benefits of coffee. Coffee does help to move fat through your body. The determining factor however might be how much coffee you drink on a regular basis, not how much you drink in a short period of time.

Hope this helps your research

Life is not a journey to the grave with the intention of arriving safely in a pretty and well-preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming, "WOW - What a Ride!" -- Unknown
lcon109 Reviewed by lcon109 on . Coffeee and Urine testing So heres my idea, I noticed that when you drink coffee if goes through your system faster than other liquids. So based on that would it be beneficial to drink coffee before a test since it travels through your system faster than other liquids which would mean it would collect less waste in your body to be tested? OR would it be useful to maybe make concoction of cranberry juice water and coffee to flush your system out, the coffee making it so that you expel more waste at a faster rate? Rating: 5
