I have participated in 2 very different programs, a twelve step program and a behaviorally oriented program.  These worked initially but not in the long-run.  I experienced hunger between meals and was preoccupied with trying to control it. This caused me to seek out a more sustainable program. The current program I am in, the Rice Diet, is working remarkably well.  It is based on eliminating sugar and salt, which are appetite stimulants and has a very strong medical component.  The Rice Diet is easiest to live with because  it prevents hunger.  The name "Rice Diet" is misleading because the meals consist of much more than rice.  They are well balanced, tasty, and very satisfying.  They eliminate craving for other foods.  It is a plan that is easy to live with for a lifetime.  I no longer experience hunger and am able to get on with my life, which is no longer controlled by appetite.
