They have learnt alot about how eating with the band can lead to good results. Some of the very first people to go through sort of went into starvation mode (their bodies did), which then lead to weight gain again when they tried to normalise their eating. There is a book written by a dietician on living with a gastric band, and she also does presentations (in Melbourne anyway). I don't know all of it, but one thing was to do with the way you chew your food. By adapting chewing technique, the stomach registers the food earlier and so you feel full earlier. This can reduce any discomfort from overfilling the tummy but also allows the person to eat a wider variety of things which gives the body the nutrients it needs and avoids snacking on unhealthy foods through boredom in the diet.

Can you get a second opinion? Just keep getting as much info on your options so you are really comfortable with the decision that you do make.
