Dr. Terry Simpson, Lap-Band Surgeon says the key to the band is not "restriction" but eating a small amount of food.  The band's job is to dim the appetite, not to stop you from eating.  

Dr. Simpson says successful patients embrace a new lifestyle, eat right, exercise and measure,, measure, measure...

It's easy to slip back into eating junk food and old lifestyle habits.  So whether you're a lap-band patients or gastric bypass the key is the same.
