If you don't like greek yogurt, regular one is not that bad either. There are brands that don't add sugars, just the "taste ingredient", or you can buy plain yogurt and add according to your own taste. Of course, there are more fats and less sugars, so it fills a lot more than the generic "low cal" yogurts. My favourite "honest" brand is Sterzing-Vipiteno, you can find it for sure in Italy/Austria/Germany.
