I think that may be a factor... my big problem with the potato hack was that my appetite for potato, specifically, just wasn't there, but there was no general appetite suppression. I could probably have done the oatmeal and brown sugar hack, the white rice and soy sauce (or canned fruit like the rice diet) hack, etc. just fine. The banana hack actually did seem to work for me.

Thanks for providing the links. I do think there's something useful to be had in all this.
