New MFP dietary guidelines

mellllls

This might sound odd but I was playing around with my MFP goals and adjusted the amount of exercise I intended to do. MFP now recommends more protein, fiber, and sugar for the same amount of calories. So then out of curiosity I tried several different goal and fitness combos to see if this would change. Then I changed my goal and exercise amount back to the original amount which I have had since 1/2013. I still have the new sugar, protein, fiber recommendations. Does anyone know what caused the change?
