>Not every day

There's the difference.

Once you spend every single day doing hard manual labor for years consuming potatoes for the majority of your calories then tell me 13 pounds is impossible.

Sure, its impossible for you now, but that's totally irrelevant. An equivalent statement would be "it's totally impossible for a human to throw a baseball at 90mph, I tried for a whole week once and I only threw 40mph."
