Onken

Onken Fat Free Natural Yogurt comes in 450g tubs and you get to have a 1/3 of the tub (150g) for only 69 calories calculating to 1 Weight Watchers ProPoint.  That's a whole 30g more than in your average single pot of yogurt!

It's great for desserts, breakfast and smoothies, with a fresh creamy taste and is easily available in all supermarkets.

Many supermarkets do there own versions, usually called something along the lines of 'Greek Style Fat Free Yogurt'.  However, most seem to have a slight higher fat/carbs/protein content, thus have a higher calorie value which equals 2 ProPoints; they are of course a little cheaper than Onken.

I guess you have to choose between lower calorie content or lower price...
