greek yogurt

hi :) i looked through before-and-after-workout snacks, and i saw that i can eat greek yougurt after the workout, but i have 2 questions. first:is this yogurt good, even if i want to lose weight? i mean, it has 10% fat

the second question: can i eat this yogurt before the workout,even if it says that you can eat it after? does this order affect weight loss?
