Hi Karaheddings,
Linda is right, it sounds like it's just oil that is being excreted. The fat that you eat takes 24 to 72 hours to be excreted. Take a look back over your food records 1 to 3 days ago and see if there is anywhere that you may have consumed extra fat. If there is any chance that this is blood you should speak with your doctor. Pay attention to the color and how long this lasts.
Let me know if you have any other questions,
Betty Kovacs, MS, RD
