If you have or your family does a history of high blood pressure or diabetes your carbs/sodium is one to watch. I think everyone should get enogh fiber but you might need to research your optimal amount. I have seen many people on MFP say they under estimate the needed amount on the fiber/protein .. not sure about the fat-to lose weight it should be low but I don't know where.
Hope you have great results from logging. It is helping me.
