Interesting... I tend not to eat just potatoes (I'm diabetic), but wonder if it would work with my typical "mash" (cauliflower, celeriac, parsnip, potato, butter, cream, salt, pepper) it isn't just potato, but may be able to get a similar effect if I cut the butter, cream, salt and pepper down.

Will definitely look into it.

Yes, there are cautions for people that are diabetic or pre-diabetic. I suspect that you can't do the strict "hack" but there could be useful ideas in there, e.g., related discussions on resistant starch.
