If you prefer a sweet breakfast please, I implore you, stay away from sugar cereals and pastries. Try Berries which are low in fructose so are a good low sugar fruit option and contain many phytonutrients.
Savoury breakfasts are a better option for most people however as they get blood sugar more balanced, which means less cravings and a more even delivery of energy throughout the day.
Scrambled eggs or an omelette are good options, if eggs agree with you. You can add fetta and olives for some healthy fat that keeps you feeling fuller and add in any green vegetables, like spinach and perhaps some peppers to spice it up.
But if you really love sweet, then try making a buckwheat pancake. Buckwheat is a seed and not made from wheat, so there are no issues with gluten, and makes delicious pancakes. Adding some maple syrup, which is a natural sweetener, makes a good topping.
You can work out what naturally suits you by noticing which type of breakfast gives you the best energy levels during the morning.
