I don't know what this particular brand is like as I don't think we have it in the UK, but another good one is Total 0% greek yoghurt. I saw someone mention it the other day on here so I think you get it in the US. This one has 52 cals, 0g fat, 0g sodium and 4g carbs per 100g. The good thing about this one is that it is sooooo thick!
I have it with chopped almonds in it and it's lovely!
