Drumroll, it looks like it's you and me against the potato hack.
From the sound of it, maybe we need to go strict primal to ramp up the fat burner hormones, and then it's okay to add in a little starch? However a whole pound is ridiculous at least for someone my size.
I'll stick with PB for the moment, thanks.
