Random idea - could be full of shit. Maybe someone knows. Here’s the question: How many pounds are in an inch of fat when that inch of fat is around a person’s waist?
Would it even be possible to determine this? Since fat has the same density in everyone (and thus would take up the same amount of space per gram), it would seem so. But I really have no idea.
So let’s say a male had a waist of 45 inches. How many less pounds of fat would he have if his waist were 40 inches? (I am not asking how many pounds of fat a man would need to lose in order to lost 5 inches in his waist, as this is an analytically different question: After all, people don’t just lose fat in one place. So a person who loses 5 inches in his waist would have lost x-pounds of fat; but a person may need to lose x + y-pounds in order to lose 5 inches.)
Relatedly: Is it possible to determine what a person’s optimal waist size should be if you had the other measurements of a person? If a person had, say, x-inch wrist, y-inch ankles, etc?
