You're right. Your friend is wrong. As a matter of fact, your friend is
_so_ wrong, I wonder if you two are talking about the same thing... do
both of you mean the same thing when you say "weighed straight after
eating"? To *me*, that seems very clear. Here:
I weigh 135 pounds <well, it's USENET; I can weigh what I want!>
I eat a 3-pound cheesecake, washing it down with 1/2-pound of kool-ade.
Voila! Now I weigh 138.5 pounds - until I piss, sweat, crap, or vomit (I
guess you lose carbon through respiration, too, but that can hardly
amount to much in a half-hour or so...).
I guess that's proably not the sort of "scientific reasoning" you're
looking for. I find it hard to get more "scientific" than that, though,
since it seems so common-sensical to me... How about this: the digestive
tract is basically on the *exterior* of the body (in the sense that we
have a continuous tube going through us, from which we _absorb_
food...). So, right after you've eaten, it's as if you were simply
"carrying around" a few extra ounces of food, right?
Anyway, you are right and your friend is wrong.
