A little hunger between meals isn't the end of the world, at least for a few days. You might find that if you eat less often, you'll get hungry less often--and if you need to, there's a good chance that you'll have an increased appetite at mealtimes. Eating when you have a craving is liable to teach the system to crave.

When they feed rodents snacks, like oreos or potato chips, the animals eat less of their regular chow, save their appetite for the snacks. I know how they feel.
