Greek yoghurt is a great breakfast option as its relatively low in carbohydrates & high in protein. You can add a variety of foods to it to spice it up.
Here is one of my favourites.
500g of Greek yoghurt , 1 tbsp of natural peanut butter , good for essential fats & high in protein. Half a banana , high in potassium & finally a few cubs of 70% dark chocolate.
