In preparation for the Lap Band Procedure, it is important to follow a very low calorie diet (VLCD) using the Lap BandOptifastprogram, in total for two weeks. The reason, to reduce the size of the liver to allow easier placement of the Lap Band during surgery. After educating the Optifast program now for many years I have modified the Lap BandOptifast program ever so slightly to get great compliance and great results in reducing the size of the liver in preparation for the Lap Band Procedure.
