Why am I hungry again soon after breakfast?
This often comes down to how satisfying the meal actually was, rather than a lack of willpower.
A breakfast built mainly from refined carbohydrates (sugary cereals, white toast on its own, pastries, sweet drinks) may leave you hungry again relatively quickly if it contains little protein or fibre. Blood sugar can also rise and fall more sharply after this kind of meal, and for some people that dip is felt as hunger, though the picture varies a lot between individuals and it's rarely the whole explanation on its own.
It's not that carbohydrates themselves are the problem: a bowl of oats with yoghurt and nuts behaves very differently from a sugary pastry, because the fibre, protein and fat change how satisfying the whole meal is. The issue is more often fast-digesting carbohydrates eaten with little else alongside them.
Protein can add more to the sense of being satisfied. A first meal built around eggs, for instance, may hold hunger off for longer than one built mainly around refined carbohydrates with little protein or fibre. That's a tendency rather than a rule; portion size and the rest of the meal matter too.
There's a psychological layer on top of the physical one, too. After a few quick-hunger mornings, you might start half-expecting to be hungry again soon, which can make you notice the feeling faster when it happens. Changing the meal itself may help more than trying to ignore the hunger.
If hunger an hour after eating happens consistently regardless of what you eat, or comes with other symptoms, it's worth mentioning to a GP rather than assuming it's simply down to breakfast choice.
