Has anyone ever been told by dr that they have done so well on preopt diet that they won't do the surgery. Or u have done bad on it so they won't.

The only time I've heard of a pre-op diet effecting a surgery is when someone cheats on it and doesn't shrink their liver enough for the surgeon to place the band safely. In that case, the person ends up going home with all the Lap Band scars but no Lap Band. Otherwise no, I've never heard of someone doing "too good" on a pre-op diet.
