I did some reading about toxins in the body and found out that fat may also be a mix of cellular waste, water, unprocessed hormones and other nasty stuff. I guess if your liver
is metabolizing this fat, kidneys have to work over time to remove this extra waste. Some might end up back in the bloodstream and you would feel icky. Sort of like the drain backing up in your basement. As I understand it, constantly flushing the kidneys is a good thing.
