Watching TV or reading books while eating is a bad habit. It tunes out the brain's messages of satiety so you end up eating more than you should.

You often don't even register the sensation of taste or the act of chewing and swallowing. This also leads to your brain craving for more intense flavors in an attempt to experience the sensation of taste, and you end up eating junk foods like candy, cake or chips. Both the French and Japanese cultures believe that it's rude to do anything when you are eating.
