What is driving

What is driving me? Today, I have a feeling that it is temptation/ low impulse control and high natural appetite. The only short term psychological benefit that I receive from food is removing the craving for food. So what does all that mean? The long term cost is weight gain. or is it? But over the last week, my weight is stable, but it will change 1 kg in a day, my morning weight down 1.5 kg from the night before. Water loss, mainly, I guess. So is the craving a natural hunger form, or just a craving? It does not feel like the gut hunger, 6 to 8 hours after the last meal. So what is it, a craving or energy shortage signal?
