I have found out that greek yoghurt is just yoghurt. Its the same as natural yoghurt. Perhaps people are contrasting it with sweetened yoghurt which i almost never eat.
So yeah, greek yoghurt /natural yoghurt is blood good stuff. Eat that. I love with stewed fruit. I'm having a stewed fruit phase. Right now its stewed apples, no added sugar. Just half a cup of reach and 1tsp of mixed seeds. So ******* yummy.
But like everything eat too much of it and you'll blow your calorie budget.
