Hi,
Yes fruit especially berries (strawberry, blueberry, raspberry) and yogurts such as Greek or plain are fine.
Watch the flavoured ones as they are often very high in carbs for the quantity with the low fat ones being often the worst.
I have either Tesco or Fage Total Greek yogurt or Onken Plain yogurt with berries most mornings for breakfast. I often add a few nuts, sugar free jelly and sometimes a sprinkle of muesli to make it even more tasty. Keeps me going until lunch.
Regards
Angie
