Watch out for sneaky sugar.

I've lost about 50 pounds and have recently gotten stuck, even though I've kept my calories in check and exercise regularly. I started looking at my numbers more closely and realized I go over my "sugar" every day. The mobile version of MFP automatically lists sugar, but on the web version you have to manually select it to appear unders settings. Anyway, even though my sugar comes from wholesome sources, like fruit I'm thinking it has something to do with my plateau. I'm not going to cut out fruit, obviously, but I'm going to watch that number and eat more snacks that have less sugar, like carrot sticks, etc. What do you guys think?
