We tend to keep doing what we are already doing (an inertia of sorts). If we are eating, we keep on eating (even if we are not hungry anymore) until an external factor stops us (e.g. the food is over).
Changing states (starting/stopping) is the hardest part, but if you trick yourself somehow to stop it's easy to just put the food aside. The question that remain is how do you stop yourself from doing what you are currently doing? Some people use an "1,2,3 technique", where you just count to yourself and once you reach three you start doing what's needed. Mindfulness also helps, where you take a breath and think exactly what you are doing and why (I am eating, I am putting my hand in the bag of chips, I am bringing the chip to my mouth even if I am not hungry and don't even enjoy it that much, this would just make me feel fat afterwards).
