if you actually read the ingredients of your yogurt you will notice sugars are added. if it wasn't nobody would buy it cause it wouldn't taste sweet, it would taste bland.
the other problem is where is the dairy sourced? the milk that the yogurt was made from is full of hormones, pasteurized and crap. so my short answer is absolutely not on the yogurt.. i see so many women especially who eat yogurt with granola for breakfast and they stay fat. if i was your diet coach i would tell you to eliminate it. have some fruit instead and if you aren't hungry then guess what? don't eat breakfast
