I lived on mostly pork rinds for a week, in all the different forms - and lost weight.
Mexican lad: "How much chicharrónes?"
Me: "3/4 pound."
Mexican lad (noticing I was a white guy): "You know they weigh almost nothing - that's quite a lot".
Me: "Yes I know, I bought that much here two days ago".
Mexican Lad: "Let me get a bigger bag."
