Here's my secret.....dirty hands (I am very serious). That's the only way food will not go into my mouth. Whenever I feel the urge to stuff my face, I do something dirty like tamper with my car's engine or dusting the house. The key is not washing your hands after so you don't go around the food. That's my method and it works for me. Somehow, I don't think it's a popular method though (scratching the top of my head and wondering why ;-) ;-) )
