Ask Marilyn: A Pound of Butter in Your Pocket
Roger Stanton of Grand Junction, Colorado, writes:
Marilyn: When the original question about the weight gain from a pound of butter was posed, I thought your answer was brilliant. But a questioner in a recent column makes the subject unnecessarily complicated. (December 16, 2012)
I approached the problem from a physics point of view. If I take a pound of food, it doesn't matter whether I put it in my pocket or put it in my stomach: It is physically impossible for me to weigh more than one additional pound. A nutritionist might claim that when mixed with vitamins, minerals, water, and oxygen, the butter could metabolize into a weight gain of more than a pound. But that would require matter that was already in the body, so the net gain would still be the weight of the butter.
Is my thinking correct on this?
Sounds fine to me, Roger!
