Here’s an interesting fact: if you’re insulin resistant (more than half the population is), then you could have a “healthy” meal like a bowl of oatmeal for breakfast, and the body’s poor insulin response actually forces all the carbs you just ate into your fat cells while denying your body fuel, thus making you hungrier. To overcome this you have to eat enough carb to still have fuel available even after your fat metabolism is satisfied. So the heavier you are the more you have to eat before you have fuel available to your body.

It’s very, very difficult to overcome genetics.
