From 8 Reasons You're Still Fat by Liz Ward, Men's Health:
If you were a rat, you'd chow down for about 15 
minutes, feel full, and stop eating. But you aren't. You probably eat so fast that your stomach hardly has time to alert your brain to tell your mouth to quit chewing before your stomach explodes.
Solution: Try this drill during your next meal. On every bite, chew, swallow, put down your fork, and take a sip of water. See how long it takes you to eat. Now, during subsequent meals, take just as long to eat, only without the drill. Another meal-prolonging trick for men with regular dinner partners: Turn off the TV, put down the Daily Racing Form, and actually have a conversation.
