Yellow Poop

Too much fat in the diet can cause the poop to look yellow. Some possible causes are:

Too much fat in the diet. Limit the amount of fat whenever you eat.
Another possible cause is that foods passes through the intestines faster than normal and it doesn't permit the bile enough time to absorb excess fat while the food is being digested.
Other times it is caused by overconsumption of meats and protein. This is something that is best left to a medical doctor to treat.
Another reason could be bacteria causing internal infections.

Some common ways to treat and stop people from pooping yellow is to change their diet by reducing the consumption of foods they overeat or antibiotics if it is caused by an internal infection.
