““You may have noticed that you sometimes feel more full about twenty minutes after you stop eating than you did while you were still eating. This is because it takes the stretch receptors in your stomach about twenty minutes to tell your brain (via the hormone cholecystokinin) how full you really are. If you eat until you experience yourself to be 100 percent full, you actually go about 20 percent over capacity with every meal. And if you do that regularly, your stomach will stretch a little bit each time to accommodate the extra food. Then you have to eat more next time to get the same feeling of fullness.””
